13 best fill valve for totos

A fill valve for Toto toilets is an essential component in the toilet's flushing system. It falls under the category of Toilet Flush Valves and is a crucial part of Rough Plumbing in Tools Home Improvement.Here's what you need to know about fill valves for Toto toilets:

  1. Function: The fill valve, also known as the ballcock or inlet valve, is responsible for refilling the toilet tank with water after a flush. It controls the water flow into the tank and maintains the water level at the appropriate height.

  2. Water Supply Connection: Fill valves are connected to the water supply line coming into the toilet tank. They typically have a threaded connection that attaches to the fill valve shank.

  3. Water Level Adjustment: Most Toto fill valves allow for adjustment of the water level in the toilet tank. This adjustment ensures that the tank holds the correct amount of water for proper flushing.

  4. Quiet Fill Technology: Some modern Toto fill valves are designed with quiet fill technology, reducing the noise generated during the tank refilling process. This is especially beneficial for bathrooms located near bedrooms or living areas.

  5. Compatibility: It's essential to ensure that the fill valve you choose is compatible with your Toto toilet model. Toto offers a range of toilets, and while many use standard fill valve sizes, it's best to check the specifications or consult the manufacturer or a plumbing professional for guidance.

  6. Easy Installation: Installing a Toto fill valve is usually a straightforward process and can be done as part of regular toilet maintenance. It involves shutting off the water supply, removing the old fill valve, and installing the new one according to the manufacturer's instructions.

  7. Maintenance: Like all plumbing components, fill valves may require occasional maintenance or replacement. If your toilet is experiencing issues such as slow filling, constant running, or water leakage, it could be a sign that the fill valve needs attention.

  8. Warranty: Some Toto fill valves come with warranties, so it's a good idea to keep the warranty information in case you encounter any problems with the valve.

  9. DIY or Professional Installation: Depending on your plumbing skills and comfort level, you can either replace the fill valve yourself or hire a professional plumber to do the job. DIY installation can save money, but it's important to follow the instructions carefully to avoid any issues.

In summary, a fill valve for Toto toilets is a critical component that controls the water supply and water level in the toilet tank. It plays a key role in ensuring proper flushing and efficient water use. When replacing a fill valve, make sure to choose one that is compatible with your Toto toilet model and follow the installation instructions for a trouble-free installation and optimal performance.

User questions & answers

Question: What is the red rubber piece for? Are you supposed to put it at the bottom of the fill value
Answer: No, the included flapper and flush valve are designed to work on toilets with 2" flush systems. Your American Standard Champion 4 requires a 3" flush valve and flapper. We recommend the 5030BP Korky 3" Flush Valve and Flapper Kit, and the 528MP Universal fill valve. If you have additional questions or need further assistance with your installation, please call us at 1-800-528-3553.
Question: We have a one piece Toto toilet. The Amazon description has this fitting a two piece. Has anyone used this part in a one piece
Answer: Yes our Complete Kit will fix no/slow refilling, running, and noisy toilets. If you have any other questions please give us a call by dialing 1-800-528-3553. We are available Monday through Friday, 7:30 AM to 5:00 PM CST.
Question: is this the same as the THU
Answer: According to Korky's website: "It has a universal design to fit all brands and features a wide range of adjustability to fit most 2-piece and 1-piece toilets. Designed to fit more toilets, the QuietFill toilet fill valve adjusts from 7-3/4 inch to 13-1/2 inch."
Question: does this fit the st743s toilet
Answer: if this is a generic 2-piece toilet with a two inch flush valve, yes, this will fit. I have used it on everything from a 1955 American Standard to a recent Kohler, and it works great.

User questions & answers

Question: Will this fit my Toto st413M toilet, with dualmax 528 fill valve
Answer: Hello, you need to order a brushed nickel deck mount tub faucet. if you don't need hand shower, I suggest you order S2091NW(3 holes installation) , its extremely high flow can fill up your tub in minutes. If you need hand shower, I suggest you order S2126NW, it is 5 holes installation. Thank you!
Question: Will this fit tsu33a fill valve? my tiolet model is cst743e. thanks
Answer: You can mount it either on the tub if your tub has holes spaced in this configuration or it can be wall-mounted. Mine is mounted directly to the tub.
Question: Why is this needed instead of the less expensive Korky R528 Replacement Cap Assembly
Answer: it hook up like a regular tub faucet pipe on each side
Question: Will this fit the tsu99a.x fill valve assembly
Answer: No it does not. The threads are not tapered, they are streight (like for a garden hose). This means they will not fit a standard supply stub-out, only supply lines (like for your toilet or sink). This means we need to find an adapter so that we can hide the whole thing in the wall. (Eg: do not try and bury a supply hose in the wall!). Sadly, I'm still trying to find what adapter will work. However, I am considering just re-threading the faucet so it fits standard stubouts.

User questions & answers

Question: does it matter what toto universal fill value for my toto toilet
Answer: The hose is actually stainless but the piece connecting it to the faucet is plastic with a stainless look.
Question: Can this be used on the ms863113 #03 supreme round one piece toilet
Answer: I'm not sure it even has one! I reduce the Flow by the faucet itself. It really pours out the water! It does have an on-off on the handheld unit but I would suggest not using that because the Plumbing between the faucet and the shower head can be faulty, and if you plug the water up at the handheld set it can cause leakage in the wall!

User questions & answers

Question: can this thu 302 valve cap be good for my toto toilet model number cst412mf
Answer: I spoke with the Toto technical support person before purchase and he stated that using a generic part would result in a repeat of my initial problem (intermittent water release from tank). He also referred me to a detailed video detailing the steps to replace it. I haven't had a problem since my replacement. Perhaps questioning someone who purchased the Korky part would be helpful.Good luck.
Question: Old one had no hole for the hose (no hose needed), new one has a hole. Should I just plug it or let it shoot into the tank? Works fine
Answer: Hello, Unfortunately, there is not a recommended replacement cap for the TSU99A.X fill valve. Please reach out to us directly. Our Technical Support team is standing by to take your call. They can be reached at 1-888-295-8134 between 8am - 8pm Mon - Fri EST and press 4 when prompted. We also have live chat on the TOTO USA website. I hope this helps and thank you for choosing TOTO.
Question: does this THU 302 valve cap have the diaphram included
Answer: Oh I hate plumbing too!! I thought ( it's been awhile since I installed it ) that an adapter to go 5/8 to 3/4 was supplied. Can't swear to that one. however you should be able to find the appropriate adapter . Good luck and dont over tighten the plastic.
Question: i have a model ST744E toilet, will this work with it
Answer: It's about six feet long. Also, if you install this unit, be sure to use the included teflon tape on the threads and don't over-tighten the fitting. It'll work just great!

User questions & answers

Question: does it include a fill tube? the images do not show a fill tube for the flapper to clip onto
Answer: In the picture from left to right: The valve, black locking nut, under which is the piece that holds tube (not shown but is supplied) to overflow tube, red washer with corresponding black locking nut*, and finally is the optional white locking tab to prevent unwanted accidental adjustments. *The red washer and corresponding nut are not used unless this is a new install. If replacing an existing valve, you will connect the existing supply hose or tube to valve. Even with new installs, you would most likely use a new flexible braided hose that comes with the proper nuts attached on both ends therefore the red washer and nut is not needed.
Question: it wil fit on 99-827 brand gerber
Answer: In the specifications for this valve, it is stated that the valve replaces s TSU18A Toto fill valve. A TSU18A is designed for a TOTO one piece toilet, either a GMAX or a Power Gravity. I used this valve for a 743S Toto toilet without a problem and it was an one piece toilet.
Question: I can not flush my toilet no matter how hard i push i can not flush. i have to manually take the cover off and operate the flush. what is wrong
Answer: No. THU9021 is a junction valve. This is a fill valve (universal) for inside of the tank. The TSU99A.X was a perfect replacement for the OEM TSU18A fill valve that started leaking after 26 months.
Question: How do I know if my toilet uses a 2 inch or 3 inch flush valve
Answer: Original part number should be TSU08A.6 http://foundmypart.com/index.php?categoryID=568&category_slug=toto-st743sSearch in totostore.us.com, TSU08A.6 replaced by TSU16A. TSU16A discontinuous and replaced by TSU99A.XTSU99A.X show Fits tank models: ST743S(R)(B) in the product description on Amazon also.http://www.amazon.com/TOTO-TSU99A-X-Universal-Fill-Valve/dp/B0097CVGWII will say it's a safe bet. Just note that you MUST adjust the value based on the instruction. I saw many review seems the users just hope for plug and play.This is UNIVERSAL fit means it will need adjustment to fit different models.Good Luck!

User questions & answers

Question: All fill valves are quiet if they fill the tank very slow, how fast does this fill the tank
Answer: Looks like a universal flush valve. Look under the tank cap and find out flush valve is compatible with your toilet or go on line Toto toilets and you should be able the same info.
Question: Is the fitting on the bottom brass or plastic
Answer: Go to Toto replacement parts and they will tell which part fits which toilet.
Question: What is the size of waterline connection
Answer: No. This is for single piece toilets.
Question: What does the description mean by small
Answer: your fill valve shouldn't be making a hissing noise. if it is, it usually means that it is leaking and not shutting off completely. i have owned a few of these and unfortunately they do not last the five years they are warranted for. i would contact korky for a replacement if you still have proof of purchase or buy another.
