TOTO THP3291A#CP – Frequently Asked Questions
1) What is the TOTO THP3291A#CP vacuum breaker used for?
It is the vacuum breaker assembly for a TOTO toilet flush valve. The vacuum breaker is the backflow prevention piece on the flushometer, sitting between the valve body and the tailpiece so supply water cannot be siphoned back out of the bowl. It is a repair part, ordered by the TOTO part number THP3291A#CP, not a complete flush valve.
2) My TOTO flushometer is spitting or leaking water at the top of the tailpiece. Is the vacuum breaker the part I need?
That is the usual symptom. When the vacuum breaker's internal check element fails, water sprays or weeps from the breaker collar on each flush. The THP3291A#CP is the vacuum breaker assembly sold as a service part for TOTO toilet flush valves, so it is the piece you replace rather than the whole valve. Match the part number to the one on your existing valve before ordering, since TOTO uses different breaker lengths across its flushometer range.
3) Does the THP3291A vacuum breaker come in polished chrome?
Yes. The #CP suffix on a TOTO part number is polished chrome, and THP3291A#CP is the polished chrome version of this flush valve vacuum breaker. If the rest of the flushometer trim in the restroom is chrome, this matches it.
4) Will the THP3291A vacuum breaker work on a urinal flush valve?
It is specified for toilet (water closet) flush valves. Urinal flushometers generally use a smaller tailpiece and a different breaker assembly, so don't carry this one over to a urinal, order the breaker that matches that valve's own part number.
5) Is THP3291A#CP a complete flush valve or just a repair part?
Repair part only. THP3291A#CP is the vacuum breaker section of a TOTO flushometer. It does not include the valve body, the handle, the diaphragm kit, or the spud coupling, so if the valve itself is failing you need those components separately.
