TOTO TSU708 – Frequently Asked Questions
1) Will the TOTO TSU708 fill valve fit a Kohler or American Standard toilet tank?
No. The TSU708 is a genuine TOTO OEM fill valve built to TOTO factory specification, and it is a universal fit across a wide range of TOTO toilet tank models, not across other manufacturers' tanks. If the tank in the unit is a TOTO, order it by part number TSU708; if it's another brand, source that brand's own fill valve instead.
2) My TOTO toilet keeps running and the tank won't stop filling. Is the fill valve the part I need?
A tank that runs on or refills poorly is what the TSU708 fill valve assembly addresses. It restores proper tank refill after valve wear, mineral buildup, or float failure, which are the three usual causes of a valve that no longer shuts off cleanly. If water is instead leaking down into the bowl from the flush opening at the bottom of the tank, that's the flush valve seal, not the fill valve, and a different part is needed.
3) Can I replace a TOTO fill valve without pulling the tank off the bowl?
The TSU708 goes in with the tank in place. Shut off the supply, flush the tank empty, disconnect the supply line, pull the old valve out through the tank shank, drop the new one in, then reconnect the supply and turn the water back on. No tank removal and no fixture replacement, which is why it works as a service-call repair rather than a swap-out.
4) Is the TSU708 a good part to stock for a multi-family or hotel portfolio running TOTO fixtures?
That's the case it's built for. Because one TSU708 covers a wide range of TOTO tank models, a maintenance shop can carry a single fill valve SKU instead of matching a valve to each fixture model in the building, and it is quiet-fill, which matters when the repair happens in an occupied unit or a guest room. It's a standard stocking item for property managers, plumbers, and MRO buyers servicing TOTO across multi-family, hospitality, and commercial sites.
