I hope this is helpful and thank you for your interest in TOTO! **Q: My 1 piece toto has one of these in it. same thing. needs to be replaced. is tsu 53a the correct replacement?*** A: Hi Paul, You will need to determine your model number in order to find the correct fill valve. You can also look under your lid for a spare parts list. Please look inside the tank for a number stamped in black ink that begins with "CST". Another option for you is to use the TOTO TSU99A.X fill valve. It is adjustable and will work in all TOTO toilets. It can be found on Amazon here: https://www.amazon.com/TOTO-TSU99A-X-Universal-Fill-Valve/dp/B0097CVGWI I hope this helps and thank you for choosing TOTO! **Q: Looking for fill valve for toilet model ST743E, will this one work?** A: I wouldn't buy it—I tried this as a replacement and it broke almost right away and was poorly made. Replaced it with this unit which is way better and works like a charm. https://www.amazon.com/Korky-528T-Replacement-Toilets-Easy-Install-Made/dp/B000FCINB6/ref=sr_1_4?keywords=toto+fill+valve&qid=1579038215&sr=8-4 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Toto toilet parts. *by F***Q on February 1, 2020* You just don’t go out and buy Toto parts.
