TOTO THP4416 – Frequently Asked Questions
1) What is the TOTO THP4416 part used for?
The THP4416 is TOTO's cold-side ceramic cartridge, a replacement valve unit that goes inside a TOTO faucet or valve body. It's the wearing part, not the whole valve, so it's what you order when the cold side drips, gets stiff, or won't shut off cleanly and the trim itself is fine.
2) Is the TOTO THP4416 the hot or the cold cartridge?
Cold only. THP4416 is the cold-side unit, so on a two-handle TOTO faucet it handles one side of the pair. If both sides are worn you'll need the matching hot cartridge as well, ordered separately.
3) Do I need to replace the whole TOTO faucet if the cold side is dripping?
Usually not. A drip or a gritty feel on the cold handle is the ceramic cartridge, and THP4416 is that cartridge sold on its own as a TOTO replacement part. Swapping it keeps the existing trim, handles, and finish in place, which matters when you're maintaining a run of matching fixtures and can't source the original faucet anymore.
4) How do I make sure I order the right TOTO cartridge for my faucet?
Order by the TOTO part number, not by the faucet name. TOTO cartridges are model-specific and the THP4416 is the cold unit for the faucets that call out that number in their parts breakdown. Pull the number off the old cartridge or your faucet's parts diagram and match it exactly before ordering.
5) Is the TOTO THP4416 a ceramic disc cartridge or a rubber washer stem?
Ceramic. The THP4416 is a ceramic cartridge, so it seals disc against disc rather than compressing a washer onto a seat. That's why it turns a quarter to a half rotation instead of several, and why sediment or debris in the line, rather than a worn washer, is the usual reason one starts weeping.
