I have a TOTO toilet which was installed several years ago. The fill valve began leaking and I replaced it with the TSU99A.X valve. It was easy to install and works perfectly. It also has a replaceable diaphragm so that then next time it leaks I won't have to replace the entire valve.

Easy enough to install, though, instructions a little hazy on where the locking wedge goes. Fills quickly and accurately, the adjustable bowl fill is nice, however again the instructions are hazy on how the included gauge is used. Common sense should prevail and just install it and set it to fill but not overfill the bowel. My only complaint is the whistle when the water runs through it. I have fairly high pressure, (60-80 PSI) and it whistles fairly loud. That certainly doesn't effect performance, but not proof of a fully tested and engineered product. Still I'd buy another.

Relatively easy to install, it works well. The only difficulty is finding which Toto model you have in order to set the right height. Once we did that, installation was easy.

I bought this to replace a 13-year old that went bad. The current version is a big improvement. It is much quieter than the old one. With the new one, it has valve to fine-tune how much water goes to refill the bowl. By adjusting the valve to not waste water in the bowl, increases how fast the tank refills.

much better than the box store stuff. i had leaks with the last one i bought there, but this one went in and worked great. the guide for setting the height with the accompanying table was really useful
