TOTO THP3284A#CP – Frequently Asked Questions
1) What is the TOTO THP3284A#CP part, and where does it go on a toilet?
THP3284A#CP is a vacuum breaker for a TOTO concealed-type toilet flush valve application. It is the backflow prevention component on the flush valve, sized 1-1/2 inch by 9 inches. If you are chasing a flush valve repair on a TOTO concealed installation, this is the breaker section, not the whole valve or the trim plate.
2) Is THP3284A#CP chrome, and will it match exposed chrome flush valve trim?
The #CP suffix on the TOTO part number is the polished chrome finish, so it matches chrome flush valve tubing and trim. On a concealed installation most of the breaker sits behind the wall anyway, but if any of it shows, the chrome keeps it consistent with the rest of the exposed trim.
3) I manage a building with TOTO concealed toilet flush valves. Do I order this part by the TOTO number or by the fixture model?
Order by the repair part number, THP3284A#CP. TOTO catalogues flush valve service parts under their own THP numbers rather than under the toilet model, so matching the breaker to your existing valve means confirming it is a 1-1/2 inch by 9 inch breaker on a concealed application. Standardizing the number across the building is what keeps repeat orders simple.
4) Does the THP3284A vacuum breaker come with the flush valve itself?
No. THP3284A#CP is the vacuum breaker assembly only, supplied as a service part. The flush valve body, the handle or sensor, the spud coupling and the wall plate are separate items, so if the whole valve is failing rather than just the breaker, you will need more than this part.
5) Why does a toilet flush valve need a vacuum breaker at all?
The vacuum breaker prevents back-siphonage, meaning it stops water from the bowl being drawn back up into the potable supply if line pressure drops. It is the required backflow protection on a flushometer, and a leaking or split breaker is the usual reason a flush valve sprays or dribbles down the tube. Replacing it with the matching 1-1/2 inch by 9 inch TOTO unit restores that protection.
