TOTO TSU812.07-A – Frequently Asked Questions
1) What is the TOTO TSU812.07-A?
It's a TOTO toilet fill valve assembly, ordered under manufacturer part number TSU812.07-A. The fill valve is the tank component that refills the tank and bowl after a flush and shuts off at the set water level. It's a replacement part, not a complete toilet or tank kit.
2) Do I need to know my TOTO toilet model before ordering the TSU812.07-A fill valve?
Yes. TOTO fill valves are matched to specific tank models by part number, so the reliable way to buy is to pull the model number off the tank (usually inside the lid or stamped on the tank wall) and confirm TSU812.07-A is the valve TOTO lists for it. The part is sold as a single assembly under that one number, so there are no size or length options to pick.
3) Does the TSU812.07-A fill valve come with a flush valve or flapper?
No. TSU812.07-A is the fill valve assembly only. If the toilet is also running between flushes or leaking into the bowl, that's the flush valve or seal side of the tank and needs its own TOTO part. Plan on reusing your existing supply line and shutoff unless they're corroded.
4) My TOTO toilet takes forever to refill or won't shut off. Is the fill valve the part to replace?
Usually, yes. A slow refill, a valve that keeps hissing after the tank is full, or water spilling into the overflow tube all point at the fill valve rather than the flush side. Water running into the bowl with no flush points at the flapper or flush valve seal instead. For a TOTO tank that takes the TSU812.07-A, that assembly is the fill-side replacement.
5) Can I use a universal fill valve instead of the TOTO TSU812.07-A?
On many TOTO tanks a generic valve won't seat or set the correct water level, because TOTO sets refill volume and valve height to match its own flush engineering. If you're keeping the toilet's original flush performance, use the TOTO assembly specified for that tank. Universal valves are a stopgap, and on low-consumption TOTO models they often leave the bowl underfilled.
6) Is the TSU812.07-A a good part to stock for a property with multiple TOTO toilets?
It makes sense as a stocked spare only if your tanks all take this same valve. Fill valves are the most common tank failure in high-traffic restrooms, so keeping the correct TOTO assembly on the shelf turns a service call into a 15-minute swap. Verify the tank model on each fixture first, since a building fitted out over several years often has more than one TOTO tank generation.
