Are most toilet fill valves universal?

The other types of toilet fill valves are the diaphragm fill valve and the ballcock fill valve. These types of fill valves are not as common and may not fit all toilets.

Do all toilets use the same fill valve?

No, all toilets do not use the same fill valve. Each manufacturer has their own design and specs for their toilets. Different toilets require different fill valves depending on the model. You will need to consult your toilet's owners manual to determine which fill valve is required.

Do toilet flapper valves wear out?

Over time, toilet flapper valves will inevitably begin to wear out. The good news is that they are relatively easy and inexpensive to replace. The bad news is that if they are not replaced, they can cause major problems with your toilet, including frequent leaks and costly water damage.


3 PACK Flush Valve Seal For Kohler Toilets, Replacement For K-GP1059291 Models By Essential Values Review:


I bought these because my toilet would occasionally not seal properly and run for a brief period of time several times per hour. The seal was certainly past its prime when it was examined. I reasoned that buying the three pack was a good idea since buying just one of these was almost the same price. Very simple to put on. Release the valve by rotating counterclockwise, remove the old seal, wipe the area with paper towels, replace the seal, and then turn the valve back on. So simple, and having two extras makes me feel secure. Without a doubt worth the pickup! Toilet no longer running!



Kohler Genuine Part Gp1083167 Silent Fill Valve Kit For All Kohler Class Five Toilets Review:


...a few installation-related cautions. The instructions are not particularly excellent, as others have noted. The height of the replacement valve must match the height of the valve you are removing from your tank. According to the instructions, you should grip the valve's shank with one hand and twist the lower portion of the valve with the other to adjust the height of the valve. The fact that you must first push up the gray, protruding lock collar you can see in the valve's photo in order to free it in order to adjust the valve in this way is omitted. After adjusting the valve height, slide the lock collar back into position. That's strange that they left it out. The fact that this valve does not come with a new fill tube caused me a minor amount of torque. According to the instructions, you should attach the new valve with the old one still attached to your existing valve. Although this is a straightforward procedure, I would have preferred a brand-new fill tube given the price of the fill valve and the claim that it is a "Genuine Kohler."



Kohler Genuine Part 1083980 3" Toilet Canister Flush Valve Kit Review:


The flush valve unit arrives fully assembled, despite the fact that the product diagram for this listing displays the parts as being all detached from one another. I was afraid I might get a box with disconnected pieces, but it was already put together. This is NOT the proper replacement canister valve if your toilet is a Kohler Cimarron 1.6 gal per flush model. This one only offers a maximum of 1.28 gal per flush. I made the error of utilizing the diagram and component numbers listed on the underside of the toilet lid to hunt up the part number for the canister valve. Big error! There, a typical part number is printed. Despite fitting, it only gave me 1.28 gal per flush as opposed to the 1.6 gal per flush we were accustomed to. Significantly different flushing abilities! To get the right part number, which was #1189001 for me, I called Kohler. We now have our earlier, more potent flushing power back thanks to that replacement's flawless performance. I made a mistake when I bought this one, thus I now owe the money. To ensure you get the correct part, I would suggest phoning Kohler before placing your order (and making sure they are aware of how much your flush volume should be). Calling them now will save you headache later on and only takes 5 minutes. Very simple to change; no plumber needed! If you're unsure how to replace something, there are several how-to videos on YouTube. It only takes ten minutes. I wish you luck!



Fluidmaster 400A Anti-Siphon Universal Toilet Tank Fill Valve Review:


When the toilet in our new home began making a spaceship-like flushing noise, I felt free to replace my first toilet part.It was not quite as challenging as I'd anticipate, and the part fit perfectly. It took me around 30 minutes to install this for the first time. I would estimate that it would take me around 15 minutes to complete if I had to do it again.What to expect if your toilet has one of those floaty balls in it is the only thing I wish they had mentioned in the instructions. Mine did, but I didn't know how to attach it to this component. It took several viewings of the images for me to grasp that the ball does not go back in:) If that had been mentioned, it might have saved me some time, but it's my mistake for not realizing that this has that floating thing built in.



American Standard 3174.105-0070A Champion Universal Replacement Flush Valve Review:


It flushes the way I would anticipate it to! There are none. I was unable to replace myself because of the toilet's design. I've changed a lot of toilet valves previously, so what ought to have been a simple project required two days off work plus the services of a plumber. The kit is missing a ring (which needs to be replaced when you take the tank off the seat portion of the toilet.) The plumber assumed I had the entire assembly because I told him I had purchased the replacement valve, and I did too! After the plumber departed, my toilet started to leak an hour later, so I hurried to the nearby hardware store to get a new ring made specifically for my make and type of toilet. When I called the plumber again, he confirmed that it was probably the ring, turned off the toilet, and then hung up. He quickly rectified the leak when he returned the next day with the proper American Standard manufactured ring. When I placed my order, I wish the requirement for the ring had been made clear in the product description. (I would have placed my order simultaneously.) I will thus deduct one star from the product for my difficulty.



Fluidmaster 400AH PerforMAX Universal High Performance Toilet Fill Valve Review:


The amount of rust-looking silt in the bottom of a tank of "clean" water removes any doubt as to why they don't last a lifetime (and explains why I drink filtered/bottled water). UPDATE 10 JULY: Well, I just bought another one to replace one I had for several years in my guest bathroom. As usual, the installation went smoothly and was simple. Wearing work gloves and tightening the huge plastic nut at the connection next to the tank results in less issues, as you can do so without overtightening it as you can with a wrench. This is something I've learnt over the years (which can actually cause a leak). Again, don't overdo it. The part that is hooked to the water supply definitely needs a wrench.Basically, you either use Fluidmaster or you live to regret it. These items aren't made to last for a few years; instead, chemicals, mineral buildup, and other factors can extend their lifespan to as many as seven years, depending on the quality of your water. They are also easy to replace and modify. Over the years, I've tried a few different brands, but I keep going back to these because of how easy they are to install and how well they are made.When they begin to malfunction, you may sometimes fix them by flushing them out (instructions are included in the package), but since they are so cheap and simple to install, it is typically just as simple to replace it.I've pretty much tried every brand, so this is what I always buy. I keep one in my closet for emergencies and change it when I need it. Nowadays, always keep one on hand.NOTE/WARNING: Almost all of the issues I've read about in other reviews can be boiled down to 3 things since, after 26 years, 2 houses, and 6 toilets, these things DON'T fail in less than 3-5 years (time varies depending on water and other random factors):When you put the cover on, be SURE your float arm or the arm connected to your handle is not binding on anything.It's likely that some debris was sent down the pipe while they were working on the water lines in your region, and that debris could have slowed or stopped this valve (the flushing procedure is in the box that may help this)Avoid using "drop in" type cleaners because doing so will reduce the lifespan of this flush valve and all others.People have questioned why this model rather than the 400A; I've included a chart to illustrate what you get for your money.NOTE: If you want to lessen the likelihood of a leak, switch off the water for the entire house rather than just the supply line to the toilet. If you turn off the water supply outdoors, you will prevent this potential issue. These valves have typically been lying there for years, and when you turn the water off and then back on frequently, they WILL leak for at least a few hours or more. This can be disregarded if the toilet water supply valve has recently been operated without incident.



TOTO TSU99A.X Adjustable Replacement Fill Valve Assembly for Toilet Tanks Review:


This was recently placed on a single-piece Toto Ultramax, and it worked well! I called Toto technical support since I was worried because the description said it was for a two-piece toilet, and they confirmed that this is the universal replacement for all models. If you're interested in learning more, Simply search for "How to Replace TOTO Universal Fill Valve" on YouTube to find a video from Toto that demonstrates how to install this. It was really helpful and very clear in demonstrating each step. The paper instructions provide a grid that outlines exactly how to alter the fit for each model in a very simple manner. Running hot water over the plastic overflow tube's end can warm it and make it much simpler to slip onto the connections, which is another good advice.



Korky 528MP QuietFILL Platinum Fill Valve-Fits Most Toilets-Easy to Install-Made in USA, Universal 99%, Black Review:


How shall I put it? I giggled quietly and nearly 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 house maintenance activity. I ALWAYS used fill valves made by Fluidmaster. Fluidmaster fill valves and Korky flaps. I did tell myself that.I decided to test the Korky after having a Fluidmaster fill valve fail after six months of use. What have I got to lose, I reasoned, considering how well-functioning and high-quality their other parts have always been. Nothing at all, it turns out.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 area than the Fluidmaster's, which is situated on the exterior. Because of where the overflow tube and flush lever are located, positioning the valve in the toilet can occasionally be challenging.The adjustment comes next. The float and toilet bowl fill on the Fluidmaster need to be adjusted for proper operation. Two incredibly clumsy instruments must be adjusted in order to do this. A plastic screw on the float constantly gives me the impression that if I move too quickly, it would break. Additionally, the fill level adjustment for the bowl is a shoddy, erratic thumb wheel that is coupled to the fill tubing. The float does not need to be adjusted while using the Korky, however. Just align the overflow tube with the silver housing and tighten. A straightforward and accurate quarter-turn valve attached to the fill valve itself is used to regulate the toilet bowl fill. Much more preciseThe performance follows. I fell in love as soon as I flushed the Korky. A brief gush of water was released by the valve, which then began to fill very quietly. There's no hissing as loud as the Fluidmaster. I also think the Korky fills the tank more quickly, though I didn't time the two valves.It seems impossible that something so simple could provide such happiness. But occasionally, the little pleasures in life are all that matter. And the Korky offers just that.
