It is ideal for use in toilets that flush 1.6 to 3.5 gallons of water per flush, and the universally designed 400A toilet fill valve can be adjusted easily from 9 to 14 inches in length. It is also compatible with most toilets with a flush valve that measures 2 inches in diameter. Because it contains replacement parts for faulty fill and flush valves in addition to flappers, a toilet repair kit can resolve the most typical fill issues that may arise.

This material can withstand exposure to chlorine and water with high mineral content. Restores the flushing action of your toilet to how it was when it was first installed. Installation takes less than ten minutes and is simple and quick.

Using a Fluidmaster Fill Valve and Flapper Kit, you can resolve the two most common causes of a constantly running toilet. This kit features the ubiquitous 400A fill valve, which is widely regarded as the best toilet fill valve available anywhere in the world.

Restore the original flushing ability of your toilet. The kit comes with a flapper that has a solid frame and is designed to always align with the tank drain to provide a powerful and consistent flush. The complete kit can be installed in your toilet in under ten minutes and will restore its ability to flush like it was brand new. A damaged fill valve and a leaking flapper are both remedied by the use of this product.

Test Result:

“To replace the fill valve that came with my toilet, I bought this Fluidmaster Toilet Fill Valve Kit (14 years old). Although I had previously replaced the flapper a few times, the fill valve as a whole was damaged (Noisy, leaking & running). This new fill valve will pay for itself in less than two months because my water bill was $5 higher than usual.

The installation process only took a few minutes. There are simple-to-follow instructions included, and no special tools are required unless the locknut that is already there under the toilet is a little seized. Turn off the water pressure at the toilet and flush your toilet to remove as much water as you can from the tank before putting any parts in or taking any out. A sponge can be used to soak up and remove any remaining water. Once I remove the nut holding the valve stem, I get a small bowl or place an old towel under the toilet to catch any additional small amounts of water. The flush arm and fill pipe were easily connected to the new valve kit and flapper. This is a simple, cheap, and do-it-yourself project.”

“What a huge relief it is to have fixed all the leaky toilets in the house finally. Installation took around 20 minutes, considering removing the old valve system. The most important thing to remember is to have Teflon tape on hand to seal the water line and to check that the float mechanism has enough room to move up and down smoothly. Before you put everything back together, I would advise just testing the system.”

“I replaced one bathroom valve with a similar Fluidmaster model years ago, and it’s still going strong. We chose to use this model to replace our other toilet this time because it started to leak near the rubber valve.

My son reported that the installation was simple and that the setup took about 30 minutes. I used always kept a big bottle of water in the back to conserve water, but with this setup, you can adjust the water level and conserve water automatically without doing so.

These seem to last long because the one in my other bathroom, which has been there for years, has never given me any trouble. I wouldn’t think twice about advising to anyone looking to upgrade or replace their current setup.

I’ve included a video comparing the Fluidmaster to the old ball type and the water level and flushing efficiency. I did not speed it up to give you a precise time limit of how long it will take for it to flush at the water level I have set it at. Even though it sounds a little loud, the toilet is not that loud when the lid is on the back of the toilet.”

Test Result:

“Excellent performance on an older model with a larger bowl we use in our second bathroom. It has a dial that allows you to independently set the water delivery rate to the tank and the bowl in two different ways. This was a wonderful feature, and it worked flawlessly in the American Standard toilet that was installed in the 1970s. Installing it was simple, and it didn’t take more than a few attempts to get the adjustment right. It was very simple to set up, even for someone like me who is just an average home improvement guy and doesn’t claim to have any special skills. Recommended.”

“Ok, my toilet started running loudly. After determining what the issue was, I watched a few videos. I concluded that I could fix it myself, thereby avoiding the need to pay a plumber several hundred dollars. The package arrived quickly and much earlier than was anticipated – a bonus!! Therefore, I immediately began installing this, and it was a breeze. I am a ” young ” woman despite being in her 50s, and I figured this out on my own. It couldn’t be simpler! The toilet is now silent and performs wonderfully!!!”

“I have been fixing the old toilet valve because I am afraid I will make a mess that is beyond repair. The thought of dealing with water terrifies me, but I did not want to pay a plumber to do something I was confident I could do myself. In any case, I could not tolerate the sound of the foghorn for a moment longer. Consequently, I purchased this valve from I read every review, and while some of them made me nervous, in the end, I decided to purchase the product. So far, so good. Simple to put in place. No more audible noises. No leaks. I will keep an eye on it, but everything has worked out wonderfully for me.”

Test Result:

“I finally decided to use Fluidmaster parts in my master bathroom toilet after years of battling with other major brand parts that were constantly failing, mostly because my wife insisted on using that dorp in toilet tank tablets. Years later, no issues at all. We are currently remodeling the main bathroom, and since I could not locate the fluidmaster locally, I had to order a new flush valve. This and the Fluidmaster fill valve I used together made my 1984 toilet operate like a brand-new one. And I have every reason to believe it will provide me with years of dependable service.”

“This is the only brand I’ll buy because I had to replace the entire interior of 3 toilets (all within 6 months—yay for home ownership!) I tried some others and had to replace them right away. This is here, exactly. Everything functions as it should and detailed instructions are provided. Despite having no prior experience, I finished the repair in under an hour. You must also take the tank out to access this specific component. So. If you’re debating between two brands, go with Fluidmaster!”

“Over the years, I’ve installed quite a few flush kits. Over that time, Fluid Master has produced some high-quality goods. Except for a flush valve that was a part of one kit and wasn’t water amount-adjustable despite its claim to be. They typically have a long lifespan. A better bowl to flush valve gasket was added to the most recent kit, eliminating the need to tighten it with a wrench, which ran the risk of weakening the rubber and resulting in leaks. Pleasantly priced Compared to the long-used ball cock system—I know, that’s the real name—seems simpler and more reliable.”

The 528MP is simple to install and comes with the following components: one 528MP Fill Valve, one Refill Tube, one Metal Refill Tube Clip, one Mounting Nut, and one Cone Washer, one Coupling Nut, one Tamper Proof Key, one Refill Adjuster, and one set of instructions.

How shall I put it? I giggled quietly and almost inaudibly as soon as I flushed the toilet after installing the Korky 528MP fill valve. I’ve been changing toilet flush valves for years. Not a major undertaking; merely a regular home maintenance task. I ALWAYS used fill valves made by Fluidmaster. Fluidmaster fill valves and Korky flaps.

The Korky valve performs better and is simpler to install and adjust than the Fluidmaster. the installation first. Korky’s float is internal and occupies much less space than the Fluidmaster’s, which is housed on the exterior. Because of where the overflow tube and flush lever are located, positioning the valve in the toilet can occasionally be challenging.

Test Result:

“I’ve had a long relationship with this brand from my time managing rental properties, and I consistently buy the platinum fill valves because they’re the best I’ve found. It’s the best I’ve found so far and will last a lot longer than the original Korky fill valve.”

“The product was well-packaged, complete, and as advertised when it was delivered the following day. It also cost less than what was charged locally at home improvement stores. Installation in a Crane toilet was simple thanks to the clear and detailed instructions that are provided. I have installed two different toilet models with this Korky 528MP fill-valve, and I am pleased with the quality, dependability, and durability of the product.”

“I bought 3 of these and 1 other brand fill valve for toilets, and they are all simple to install. Installing is only difficult if your toilet has a CT416 tank from Toto. To access the water supply line connector, the tank must be taken apart. The sleek design of these Toto toilets, which lack any obvious intestine-like bumps on the sides, makes maintenance difficult. Unknown why, but two of the Korky are quieter than a third one, and they all function properly. I hand-tightened all 4 of my replacement fill valves, and there have never been any leaks. I am aware that some videos advise tightening connectors 1/4 turn, but I find that wearing gloves gives me a good tight grip and turning strength.

A suggestion to ensure the ideal installation of height. Before installing the replacement, check the height of the new one against the old fill valve. The rubber hose measurement is the same. Before using the toilet, it is simple to cut the hose to the right length.”

Twisting and ghost flushing are both prevented by the solid frame.

It eliminates the most common cause of a toilet that is constantly running.

Test Result:

“Works flawlessly for my 1.6-gallon toilet, which had a worn-out blue flapper when we first moved in. Since this is a water-saving flapper, removing the small piece inside the bottom of the flapper is important if this is happening to you. I had some problems with it not staying up after a flush. The flapper will be filled with water if you can get rid of that little piece, allowing it to stay up when you flush. The dial will then function exactly as stated!”

“This works fantastically after I just installed it. It resembles the one I had in every way. It is simple to install and clips into place. I simply needed to unclip the old one’s clips and clip this one down in its place. My previous one lasted ten years. So far, I like how simple Fluidmaster parts are to maintain. The 2-inch drain pipe is the specified measurement. Since I’m not a plumber, I almost bought the 3-inch one, thinking it was the size of the drain rather than the stopper. I’m glad I read another review about it because otherwise, I might have chosen the incorrect size. I considered including that information for other DIYers.”

“Perfect substitution. I assume you know what it is if you are viewing this. The old one didn’t create a strong seal because it had grown harder over time. As a result, the toilet bowl constantly had water leaking from the cistern. This consequently required refueling every 10 to 15 minutes, which annoyed me and was a waste of water. It was easily replaced in under 30 seconds and is now working perfectly. How long will this one last? Let’s see. If it is less than two years, I will return and deduct a star.”

“Despite having little to no experience with toilets—aside from, you know, using them—I could install this without too much difficulty. I noticed that it didn’t flush properly on some toilets. The flush lever would not move “up” when I would pull it. To get the water to flow, I had to press down on the lever.

Trial and error revealed that I hadn’t installed it properly, though. You will experience an improper flush if the chain is either too long or not long enough. To correct this, remove the chain from the clip and place it in a position that will allow it to be fully pulled down and up when the lever is pulled.”

Test Result:

“Despite changing the flapper valve and adjusting the water level, among other things, the older two-piece toilet I have in our basement bathroom was not flushing properly. So decided to use this kit to replace the old mechanism.

Very simple to complete with basic tools and fairly clear instructions. The only useful tool is a large adjustable channel lock or pipe wrench to remove the old plastic nut from the bottom side of the tank, below the flapper valve assembly, which is not mentioned in the instructions. A scraper is also useful for removing the old seals. Took around 40 minutes, cleaning up included. Now the toilet flushes like new.”

“A constant internal leak plagued my toilet. I probably just needed to replace a gasket, but I’ve never been happy with the quality. I’ve completed Fluidmaster kits in the past, but it’s been a while. I wasn’t expecting much, but the instructions were fantastic, incredibly easy to follow, and beautifully illustrated!! I was very taken aback! Ordinarily, these instructions are terrible, especially from a plumbing company selling inexpensive toilet kits. Very good material. Well done, marketing group or whoever. I had to purchase an extra-thick gasket ring for my Gerber that was not included in the kit, but it was also a good Fluidmaster component.”

“Water began to leak from the flush lever opening when the old fill valve stopped working. I discovered the overflow pipe hadn’t been trimmed at that point by the previous installer. I decided to buy this kit, a few tools, and replace every component. Watching a YouTube video took an hour of your time. Installation takes one hour with a careful reading of the directions. Works flawlessly. FWIW, the fill valve that malfunctioned was also a Fluidmaster; however, I don’t mean any offense; I know that things like this don’t last forever. Controlling the fill tube rate is one feature I value. For me, being slower is preferable. The water flow is still sufficient to fill the bowl as the tank fills more quickly. Clever.”

7. Kohler Genuine Part 1083980 3″ Toilet Canister Flush Valve Kit, 2.50 x 1.50 x 9.00 inches

The engineers at Kohler developed this flush valve to preserve the original product’s performance while also increasing its lifespan. Install a brand-new OEM Kohler flush valve in place of your worn-out or leaking one. Make use of a soft cloth or sponge that has been dampened. When cleaning surfaces, you should never use an abrasive material such as a brush or scouring pad.

If you are interested in purchasing this, it is highly likely that you are doing so because the rubber seal on the tube that raises up and flushes the toilet has become worn. It will come off if you just give it a little bit of a twist. You will only need to replace this component with the new tube and not the entire assembly if you follow these instructions. The original flange that is currently located inside the tank ought to be perfect in every way.

  • The original component was made by Kohler.
  • Canister flush valve kit for toilets manufactured by Kohler Cimarron.
  • Canister measuring 3 inches in height, with an outlet measuring 3 inches.
  • Just the Kohler Cimarron 1.6gpf tank with the model number K 4634 is compatible with this part.
  • It is possible to find the model number of the tank by looking inside the back wall of the toilet. Material: Plastic. After immediately applying the cleaner, wipe down surfaces and thoroughly rinse with water to remove any residue. Any overspray that lands on nearby surfaces should be rinsed off and dried.
  • Full assembly, including the gasket connecting the tank to the bowl. Inlet diameter: 0.5 inches.
  • This is not a product that can be worn by anyone.

Test Result:

“With this kit, fixing my Kohler toilet was incredibly simple for me. Since I am not the least bit mechanically inclined, I did nothing but wait in the vain hope that my toilet would somehow self-correct when I started to notice signs that it was not sounding right. I was, indeed, seriously in denial. Then it simply stopped working. I used the dysfunctional signs to search online. Voila! There were numerous self-help tips and demonstrations available. I decided to purchase the canister valve assembly kit as a result. It was simple to take out and replace the old canister. I spent seven minutes on it. I’ve been widowed for seven decades. A plumber was not something that could be hired. Before deciding to handle the issue myself, I sought advice from two handymen. I required a new toilet, one said (and he just happened to have one for sale). The other claimed he could resolve the issue but that it would take several hours and that he would need to be compensated accordingly. Hence, my choice of online self-help. I placed the order for the Kohler parts, followed the instructions, gave myself a pat on the back, did a little happy dance, and flushed my toilet one more time just for fun. The Kohler canister valve assembly kit receives a rating of 5 stars.”

“The top tank and bowl of a Kohler toilet started to leak. Three seals cover the flush valve. Replace this seal if the toilet runs continuously. The second seal is under the flush valve (mine is red in color) and seals the interior of the tank to the flush valve. One seal (mine was yellow in color) is used within the flush valve to prevent water in the tank from leaking into the bowl. Water would leak between the top tank and bowl if this seal were to break. The third seal, which fits under the tank and rests on top of the bowl opening in my case, is gray. This was the actual seal that failed on mine. In the end, I had to remove the entire flush valve, which required a lot more time and money than simply changing the gray seal. The flush valve is not necessary to replace the gray seal because it is so simple to do so.”

“After 20 years of dependable service, I completely overhauled my Kohler K4634. the new water fill valve, the upgrade to the Kohler canister, the steel plate, and the seals. The original flapper setup wasn’t as simple to replace as the rest of the equipment. The large plastic nut on the tank’s bottom wouldn’t budge, so I used a screwdriver/chisel and hammer to disassemble it on the workbench. Try not to do it in the restroom. I was back in business with a more refined and quiet toilet after adjusting the fill valve and performing a test flush. Inconsistent flushes were the issue. Solids are very disappointing, fluids are poor to ok flush. a low water pressure and a lot of bubbling. Occasionally, two flushes were necessary. Consider fluid dynamics; the solution is simple.

An air lock results from turning a full gallon jug upside down to empty it. In the tank, the same thing is occurring. The solution is to cut a length of 3 inches of duct tape in half. Apply two layers of tape to the top of the left or right tank side, just beneath the cover. No more air lock and constant power flushing.”

8. Kohler Genuine Part Gp1083167 Silent Fill Valve Kit For All Kohler Class Five Toilets,12.5″ x 3.5″ x 3″

The engineers at Kohler developed this fill valve to preserve the original product’s performance while also increasing its lifespan. Put in a brand new fill valve from Kohler to replace the leaking old one. A gracious experience is provided by silent fill because it fills the tank in a quiet manner.

Multiple fill rate inserts are provided to ensure that performance is maximized while water usage is minimized. It can be adjusted to fit people of varying heights. When cleaning surfaces, you should never use an abrasive material such as a brush or scouring pad. Determine the correct part by checking the color of the shank; if it is black, use this part; if it is gray, use GP1138930.
There is no set cap color.

When the original fill valve on our toilet failed, it became impossible for water to enter the tank unless the user tapped the top of the fill valve. This happened quite early in the toilet’s lifespan. At first, we attempted to replace it with something equivalent to a Universal Fluidmaster 400. It was functional but a lot noisier than the original version. As a result, we decided to purchase this unit, and we immediately noticed a difference. They are extremely comparable, except that this apparatus has a restriction at the point where the tube is attached.

It’s also possible that things change closer to the bottom. When using the old valve, it filled up quickly, but the bowl held significantly less water than it does now. Compared to the universal unit, this new one fills up at a slightly slower pace, operates at a significantly lower noise level, and provides a more pleasurable experience. Therefore, we now comprehend the logic behind why it is preferable. We have high hopes that it will outlast the factory-issued valve (which we tried cleaning and lubricating to no avail).

Test Result:

“Due in large part to the fact that I was replacing the same component that had stopped properly filling the tank after 12 years of use, this repair took less than ten minutes.

If you find yourself in a similar situation, take note that you can simply slide the lock ring toward the top of the valve assembly, pull the assembly off the base, and then replace it with the same part from the package as long as the base that connects to the water supply is in good shape (likely). You don’t need to worry about leaks, drain the tank, or turn off the water supply. If necessary, how-to videos on YouTube are available.”

“On the same land, I built the homes for my mother, wife, and myself. I have seven Kohler toilets total, all of which I adore. However, these items (the plastic components) require replacement every three to four years. If you didn’t know, you can remove the gray band, remove the entire valve assembly, and replace it without changing the component attached to the tank. Replacing almost the entire thing takes just ten minutes. The parts that go through the tank are only infrequently in need of replacement. Every three or four years may seem like a lot to you, but not me. Other restrooms, it happens annually.”

“My Kohler toilet began to hiss during refill moderately, so after removing the fill valve unit’s top gasket to clean and rinse it, along with a flush without the top, the hissing persisted. I located this replacement kit by comparing the toilet model number stamped inside the tank. The quick delivery from Amazon saved me from driving to Home Depot, where I would have likely spent more money on unnecessary items.

I was initially a little intimidated by the kit because it comes with extra parts that aren’t necessary. After watching Kohler’s installation video, it only took a little over 10 minutes to replace the fill unit. Once again, it is quiet during refill.”

9. Korky 427BP Flush Valve Seal For Mansfield 210 and 211 Toilet Repairs , Red

The Mansfield 210 and 211 valve seal is made to fit both 2-inch Mansfield flush valves models 210 and 211. The 427 comes with one valve seal and is simple to install.

I shared the same fate as some unfortunate homeowners in having the low-quality Mansfield 210 toilet installed by the builder. And because I was duped by false advertising into putting the cursed bleach tablets into the tank, the rubber valve was inevitably damaged, resulting in a stuck flush. Like most homeowners, I continued to put off dealing with the problem even when flushing the toilet required a lot of force. The stars were in the wrong alignment one fine day, and my futile attempts to operate the broken flush lever broke the stopper mechanism.

At this point, I realized that my problems with a stuck valve could have been resolved in less than a minute by simply replacing this valve seal; if you have a Mansfield toilet, you probably already know that fixing the broken stopping mechanism required removing the entire tank. OMG. After an unnecessary hour of replacing the entire stopping mechanism, I immediately ordered three valve seals to fix my other toilets, which were also having issues. They were all replaced in under two minutes, sparing me a lot of trouble in the future.

So, to save yourself future hassle and money, stop using bleach tablets and replace the flush valve seals on the cheap if you have a habit of doing so and your flush handle requires a lot of effort to operate. Do not wait until the stopping mechanism is broken.

Test Result:

“People in my neighborhood began griping about how difficult it was to flush the toilets a few years ago. In other words, it was getting harder to depress the flush lever. Then mine started acting the same way. The plumber was called by some neighbors, who paid $75 for the repair. One of the neighbors chose to replace the toilet completely! I looked it up online and learned that the issue was that this tiny rubber gasket needed to be replaced because it wore out so quickly. It couldn’t have been THAT simple. I purchased one.

It only required turning off the water valve, flushing the tank to drain it, removing the small water fill tube from the top of the middle-of-the-tank float stack, screwing off the top of the stack, removing the housing, removing the old gasket, replacing it with the new one, and then reassembling everything. Make sure the gasket is seated in the groove surrounding the stack’s base. Additionally, the lever trip handle may be difficult for some people to maneuver, but I always simply move mine out of the way. To assist with this, there are instructions available online. This took longer to type than it did to change the gasket.”

“It leaked when I installed it, as other reviews have stated. I discovered that you must make adjustments until the leak stops. Imagine putting on a shirt. You insert both arms, but you’re not quite done. Until it is in the proper position everywhere, you must shift it here and smooth it there. That’s how this valve works. It won’t leak once you’ve smoothed it and placed it properly.”

“These gaskets are a great value and perfectly fit Mansfield toilets. HD sells for about two dollars each, while OEM seals cost more than four dollars. In all relevant ways, these are the same. Simple to install; just make sure the seal is completely positioned in the top groove by rotating it in the slot. Normally, I just gently bend out of the way to release the flush handle without removing it. It only takes ten minutes from beginning to end to change a seal! Regards, Amazon!”

Test Result:

“It took a long time for my tank to fill before my old fill valve totally failed. I ignored it because I couldn’t tell what the problem was. I continued reading reviews and other material after it completely stopped working before choosing which one to order. I had to use a pitcher and the bathtub faucet to fill the tank during that time. Although it’s not a big deal, it was so satisfying to finally install the new one! Lol. Installation went smoothly. It’s been a few months, and so far, it’s still functioning flawlessly. Woo-hoo!”

“As a useless Millennial, I take pride in attempting to complete small DIY projects around the house. The instructions are included, and it was fairly simple to figure out. The fact that my toilet tank is hidden beneath a countertop makes replacing it more difficult than it should be, but the fluidmaster is not to blame for that. Anyway, the point is that if you’re like me and will ruin a wall trying to remove a baseboard, just know that you can do this. If you install it successfully, take pleasure in your irrational sense of accomplishment.”

“It’s partly my fault because I didn’t understand how to adjust the water level in the tank before I installed the appliance. Before installing the unit, you should adjust the water floater’s height. After installation, you must rotate the water height 360 degrees in order for it to function. It is difficult when the tank bumps into the rotating part after you have correctly positioned the filler tube and other components, which I had to take out in order to rotate. I was mistaken when I assumed it was a slider retainer height! Hope this aids in installing this unit for someone else.”

“One of my toilets needed a replacement for an old fill valve, and Fluidmaster is the way to go. Although installation was fairly simple, the instruction manual that came with it was not very helpful. It only took a little over 30 minutes to remove the old one and replace it after watching a few online videos. The fact that the device is entirely plastic gives me pause, but other than that, it seems sturdy and functions as it should.”

Types of Toilet Flush Valves

Standard, 3-inch, 4-inch, tower-style (also known as canister-style), and dual flush valves are the different types of toilet flush valves.

Standard Valve

Most low-flow toilets and older toilet models are compatible with the 2 inch standard flush valve. It is the least expensive and most frequently purchased toilet flush valve and is most frequently found in residential buildings.

This particular style of toilet flush valve consists of a hinged flapper that fastens to the overflow tube’s base directly and also fastens to the top of the tube with a chain. To prevent water from entering the toilet bowl, the flapper rests in the flush valve seat at the base of the toilet. A large plastic bolt that fastens the flush valve to the tank through the hole in the tank bottom is located on the flush valve seat and must be fastened from the tank’s bottom.

3-Inch Flush Valve

A 3-inch flush valve is made for toilets with a 3-inch opening in the base of the tank and has the same design as a standard flush valve. The larger opening enables more water to enter the tank more quickly, increasing the toilet’s flushing power so that users don’t need to double flush.

4-Inch Flush Valve

The typical 4-inch flush valve has a bump in size that provides a more potent flush as the water flow into the toilet bowl increases and is designed for toilets with a tank-to-bowl opening of approximately 4 inches. Beyond this size difference, the valve’s design and functionality are identical to those of standard and 3-inch flush valves.

Tower (Canister) Flush Valve

Depending on the toilet, a tower- or canister-style flush valve can be found in a variety of sizes. These flush valves use a vertical flapper that is located directly below the overflow tube in place of the standard flush valves’ delicate hinged flapper, which is a frequent point of failure. With this design, you can increase flushing efficiency without expanding the size of the flush valve by creating a 360-degree flow through the base of the toilet tank into the toilet bowl.

Dual Flush Valve

Dual flush valves sit directly on top of the tank-to-bowl hole, similar to the tower- or canister-style flush valves. These valves provide both a low-flow and high-flow option, allowing you to choose the low-flow flush when there is only liquid in the toilet to reduce overall water consumption.

This type of toilet flush valve might have a flush button system with a low-flow button and a high-flow button. As an alternative, it might have a flush lever system that can be depressed for a high-flow flush and raised for a low-flow flush. The flapper is entirely removed from the tank-to-bowl hole for a more powerful flush that eliminates solid waste when a stronger flush is required and you use the lever or button appropriately.

Best Toilet Flush Valve Buying Guide


To ensure a long life without leaks, the material a toilet flush valve is constructed of is crucial. A toilet flush valve should generally last six to seven years, more or less, depending on the strength of the cleaning agents used, how frequently the toilet is used, and the water quality.

Rubber and ABS plastic are sturdy materials that defend against rusting, corrosion, and wear. Both materials are inherently resistant to the harm that water damage can do over time. Although metal runs the risk of rusting and breaking, especially if your home has hard water, stainless steel is a strong alternative that offers a higher level of strength and durability.


Toilet flush valves are made to fit particular models of toilets. Due to this requirement, even if the basic sizing (2-inch, 3-inch, or 4-inch) matches, not all toilet flush valves will function with all toilet models. This is due to the possibility that various toilet manufacturers may not use measurements that are considered industry standard. When this happens, even though your toilet calls for a 3-inch flush valve, you might be stuck with one that doesn’t quite seal.

Look for a flush valve made by the same company that makes your toilet and consult the manufacturer’s instructions for the precise product number listing to make sure you are buying the right one. If you’re unsure, look for a universal replacement kit that can fit many different toilet model types, but be sure to get the right size (2-inch, 3-inch, or 4-inch) for your toilet.

Installation simplicity

For those without prior experience working with toilets or plumbing in general, replacing a toilet flush valve can be difficult as far as do-it-yourself projects go. In order to make the repair, the water supply must be disconnected, the tank must be drained and dried, and the water at the toilet must be turned off. Then, remove the flapper, the (two or three) tank-to-base bolts, lift the tank, remove the rubber gasket, and loosen the flush valve nut in order to remove the flush valve.

Find a toilet flush valve that matches your current setup as closely as you can to make this project easier. This way, you won’t have to worry about changing the height of the overflow tube or the seal at the base of the tank. Look for a product that comes with all the parts you need for the job, along with detailed installation instructions.

Included Elements

Before buying a replacement toilet flush valve, examine your current tank setup, including the rubber gasket, tank-to-bowl hardware (nuts, bolts, and washers), and any additional fasteners. Find a toilet flush valve kit that includes the components you need to replace your current toilet flush valve and the toilet’s fastening hardware if you notice rusting or wear in these areas. If not, you might experience a leak in the near future. To avoid accidentally installing the flush valve incorrectly, look for a product that comes with these components included. This will make it simpler to follow the guided installation instructions.

Watertight Seal

A toilet flush valve’s primary function is to create a tight seal between the tank and the toilet. Therefore, it is not surprising that the majority of flush valve manufacturers assert that their products have a leakproof seal. This claim may be accurate under certain conditions or for some time.

Finding a flush valve that is both size and type compatible with your toilet and has a heavy, durable flapper that fits snugly in the tank-to-bowl hole seat of the toilet flush valve will help to ensure a secure, long-lasting leakproof seal. To stop water from leaking between the gaps in the materials, the gasket between the tank and bowl should also be made of high-grade rubber that can flex to form a strong seal.

Water Conservation

You can reduce your water bill costs by using a toilet flush valve with water-saving features. The less water used when flushing the toilet, you will have to pay for less water.

Low-flow toilets frequently employ standard 2-inch toilet flush valves because of how little water can pass through to the bowl due to their small size. To save water when you only need to flush liquids, you can also purchase a dual-flush valve with a low-flow flush function. A product with an adjustable overflow tube is another choice; this will prevent the tank from filling up with as much water, resulting in fewer flushes per flush and less water being used overall.

Plunger or ballcock

Ballcocks and plungers are old types of fill valves, and their typical components are a brass arm and a float ball. A ballcock valve is affixed to a brass assembly that is sealed off with a rubber washer. Buying a new rubber washer is the only way to “fix” a spoilt rubber washer. As long as everything comes out in one piece, everything is fine.

The diaphragm

However, primarily plastic is used in diaphragm-style valves. However, the diaphragm repair style may be a bit more difficult since the float arm, and the ball appear similar to plungers. However, you can only replace it with a new one. Because they tend to be very affordable, you shouldn’t have any trouble replacing them as necessary.

Floating ballcock

A floatless ballcock, also known as a cupless ballcock, has a diaphragm that can sense the level of water at the bottom of the tank. In fact, it is ideal for tanks with low profiles. In addition, you can easily adjust the floatless ballcock. A simple turn of the top valve screw is all it takes to accomplish this.

Type of cup

Among all the types of fill valves, the container type is the latest and the last type. The chances of seeing a toilet with a cup type are very high when you purchase a new toilet. Besides being adjustable, this type of fill valve can be used in any type of container. You’re already set as long as the size is between seven and thirteen inches.


Choosing a toilet flush valve with a warranty is also a smart move. These products are sometimes beyond our control, so we need to buy models with warranties, in case anything should go wrong.

Frequently Asked Questions

Are all toilet flush valves the same?

It’s not. Standard flush valves, tower- or canister-style valves, and dual flush valves are some of the types of toilet flush valves.

How do I choose a toilet flush valve?

For reference, check the hole in the bottom of the tank for the flush valve drain valve. A 2-inch seal is needed if you’re dealing with an orange or baseball. You need a three inches wide seal if it looks more like a grapefruit or softball.

How much does it cost to replace the toilet fill valve?

Depending on local costs and the worker’s qualifications, a plumber or handyman can charge $50-$150 for replacing certain parts like a fill valve or flapper. Shutoff valves usually cost $25-$50 to replace, and wax rings can cost $50-$200 to replace.

Can I use any flush valve?

It is common to find concealed toilets and older models with flush pipes connecting to the pan. Both types of valves can be used in either case. To determine whether your machine flushes, you need to know what type of machine it is.

Can you clean a toilet fill valve?

In order to dissolve the build-up on the outside of the fill valve, use vinegar and an old toothbrush to break down and remove it. After cleaning the valve, rinse it with fresh water after washing it with warm soapy water.
