TOTO THP3450 – Frequently Asked Questions
1) What is the TOTO THP3450 part used for?
The THP3450 is a TOTO solenoid valve unit that serves as the flow regulator inside a faucet. It is a faucet component, not a standalone fixture, so it goes into an existing TOTO faucet body rather than replacing the faucet.
2) I manage a building with TOTO sensor faucets that have stopped running. Is the THP3450 the part I need?
If the failure is in the valve that opens and closes the water path, the THP3450 solenoid valve unit is the replacement part for that function on a TOTO faucet. It won't address a dead sensor eye, a power supply fault, or a clogged aerator. Confirm the THP3450 is the solenoid called out for your specific TOTO faucet model before ordering, since TOTO uses different solenoid units across its faucet lines.
3) Will the THP3450 change the flow rate of my faucet?
The THP3450 is the solenoid valve unit that regulates flow in a TOTO faucet, so replacing it with the same part restores the faucet's original flow behavior rather than altering it. If you are trying to change a faucet's flow rate, that is normally done at the aerator or spray outlet, not by swapping the solenoid.
4) Does the TOTO THP3450 solenoid valve come in different finishes or sizes?
No. The THP3450 is sold as a single configuration with one part number. It's an internal faucet component, so finish is not a factor and there is nothing to select when ordering.
