TOTO THP5377 – Frequently Asked Questions
1) What exactly is TOTO part THP5377?
THP5377 is TOTO's check valve assembly supplied with its gasket, a service part for TOTO automatic (sensor) faucets. It works with the faucet's solenoid valve on the autofaucet water line, so it is ordered as a replacement component rather than as a complete faucet.
2) Does the TOTO THP5377 check valve come with a gasket, or do I need to order the seal separately?
The gasket ships with it. THP5377 is the check valve assembly with gasket, so a maintenance tech replacing a leaking or stuck check valve on a TOTO autofaucet does not need a separate seal line item.
3) I'm standardizing restroom repair parts across a building of TOTO sensor faucets. Is the THP5377 a single part number for all of them?
THP5377 is sold as one configuration only, with no finish, size or voltage choices to specify, so there is nothing to select when you stock it. That said, it is a TOTO autofaucet solenoid-side service part, and TOTO publishes different repair parts by faucet model. Match the part number against the model numbers of the faucets you run before setting it up as a shelf item.
4) My TOTO automatic faucet keeps dripping or runs on after the sensor shuts off. Is a check valve the part to replace?
A check valve that no longer seats is one common cause of weeping at the spout on a sensor faucet, and THP5377 is the TOTO check valve assembly with gasket for the autofaucet solenoid valve. If the faucet instead fails to turn on at all, or cycles with the sensor but passes no water, the fault is more likely the solenoid or the sensor/control side rather than the check valve.
5) Is the TOTO THP5377 a complete solenoid valve or just the check valve?
Just the check valve assembly and its gasket. It is a component that serves the solenoid valve on a TOTO autofaucet, not the solenoid itself, so if the coil or the valve body has failed you need the solenoid valve assembly for your faucet model instead of this part.
