Does Korky fill valve fit Toto?
The genuine TOTO universal fill valve by Korky is designed to replace all TOTO fill valves including: drake, eco drake, Ultra max, and all other TOTO toilet models. Designed to fix no/slow refilling, running, and noisy toilets, the fill valve is quieter than other fill valves.
Does fluidmaster work on Toto?
Toto does not use the Fluidmaster 400A as original equipment, although Fluidmaster now makes a version of the 400A that has an adjustable refill rate so that it can be installed in Toto toilets as a replacement (but only that version.)
Does fluidmaster work on Kohler?
Fortunately, yes. A commonly known aspect in plumbing is that Fluidmaster actually makes the parts for Kohler toilets. Sometimes they are rebranded and built to the specs for Kohler’s requests, but the innards are the same!
