TOTO THP3041 – Frequently Asked Questions
1) My TOTO sensor fixture runs constantly or will not shut off. Is THP3041 the part that fixes it?
A fixture that will not stop running or will not respond to the sensor is usually failing at the solenoid and diaphragm, which is the assembly that opens and closes the water path on command. THP3041 is that assembly for TOTO. Replacing it as a unit changes both the solenoid coil and the diaphragm at the same time, which is why TOTO supplies it as one part number rather than separate pieces.
2) Is TOTO THP3041 a universal solenoid that fits any brand of flush valve or faucet?
No. THP3041 is a TOTO service part and should be treated as brand specific. Solenoid and diaphragm assemblies are matched to the valve body they seat in, so a Sloan, Zurn or American Standard valve needs that manufacturer's own repair kit. Match THP3041 to the TOTO model number stamped on your fixture before ordering.
3) What exactly is the TOTO THP3041 repair part?
THP3041 is a TOTO solenoid and diaphragm unit, the electrically operated valve assembly used in TOTO plumbing fixtures. It is a replacement component, not a complete fixture or flush valve, so it goes into an existing TOTO unit rather than standing on its own.
4) How many versions of THP3041 are there, and do I have to pick a finish or option?
There is one version. THP3041 is sold as a single configuration with no finish, size or handing choice to make, which is normal for an internal valve component that never shows once the cover is on. Order the part number as written.
5) Should a facilities team stock the THP3041 solenoid as a spare?
It is a reasonable MRO stock item if your building runs TOTO sensor fixtures. The solenoid and diaphragm is the wear point on an electronic valve, since the diaphragm is a rubber seal in constant contact with water and debris, and having the unit on the shelf turns a running-fixture call into a short swap instead of a shutdown. Stock it against the specific TOTO models you have installed.
