## Description

Universal, genuine toto Replacement toilet fill valve, for all toto toilets, adjustable refill ratio for optimum performance, easy to install, adjustable height, boxed. The product is manufactured in china. Easy installation and easy handling.

Review: Easy to install, works perfectly - I used this to replace a similar model and it was very easy to do. The instructions are clear and it took me about 15 minutes to replace on my Toto toilet. Note that this is the 528GT model. I bought it because it has an additional valve to control the water flow and I thought that would be good. In fact, it really does nothing and I just took it off to make things more simple. I suppose you would use this (I suppose because I'm not a plumber or a mechanical engineer) if your water flow into the toilet is too strong and you need to cut down the rate of flow. Otherwise, you'll just leave the valve fully open and it serves no purpose other than to be something that could cause a problem. If your water pressure is not too high, save yourself some money and buy the 528T model. This is not the first Korky product that I have bought and they produce good products. I am very satisfied with this unit as I have been with the other products from them. And, btw the unit I replaced was also a Korky but it failed due to human (this human) error. It would probably have remained in place for the next 10 years if I hadn't tried to adjust it incorrectly.
Review: Works well - Quite easy to install. Adjustment of height worked but does require some care. The control for filling the bowl was very convenient and was easy to adjust. It took about 30 minutes to remove the old one and install the new.

## Questions & Answers

**Q: Will this replace the toto tsu99a.x universal fill valve?**
A: Yes, It will.

**Q: Will this replace the tsu16a**
A: I do not know.  There are some variations and we looked carefully at the Korky site to match our toilet to the Toto filler valve.  Suggest you do the same.

**Q: Will korky blue 528gt repair toto aimes #ms626214cefg?**
A: The toilet I used it in is marked CST604CEFG inside the tank. The Korky fill valve has worked fine in that toilet. Under the tank lid there should be a sticker that shows the fill valves used in the various Toto toilets. If you can determine that your toilet and mine use the same fill valve specified by Toto, then I suspect this one would work in your unit. Hope this helps.

**Q: can this be used on a Kohler Ralito toilet?**
A: I do not know.  Suggest you email seller and ask them.

### ⭐⭐⭐⭐⭐ What was old is new again
*by A***) on 6 November 2018*

It's a toilet repair kit. Yeah. But it was easy to install and solved my problem. The quality appears to be good. Install took less than 5 minutes. Do test the instructing as the kit fits multiple models, but adjustment only takes a second.
