TOTO THP4664 – Frequently Asked Questions
1) Is TOTO THP4664 the right repair part for a dripping TOTO faucet?
If the drip traces to the stem or spindle inside the faucet handle, THP4664 is the TOTO stem/spindle service part for that repair. If the leak is at the spout base or under the deck, it is a seal or supply issue, not the stem, and this part will not fix it.
2) How do I order the correct TOTO faucet stem by part number?
Order it by the TOTO manufacturer part number THP4664. That is the only configuration this stem is built in, so there is no handing, size, or finish choice to specify with it.
3) Does the TOTO THP4664 stem work on showers or tub valves too?
No. The THP4664 stem is cataloged for faucet use only. For a shower or tub/shower valve, you need the cartridge or stem specified for that TOTO valve body, not this part.
4) Is THP4664 a whole faucet cartridge or just the spindle?
It is the stem and spindle component, not a complete faucet or a full trim kit. If your repair also needs seats, springs, or an aerator, those are separate TOTO service parts and have to be ordered alongside it.
