400A – Universal Fill Valve
Fluidmaster’s 400A universal toilet fill valve is the #1 best selling fill valve in the world! This is an anti-siphon design with an adjustable height from 9″ to 14″.
The 400A will work in most toilets including some 1 Piece toilet models. To see if the fill valve will fit in your toilet measure the flush valve drain (overflow pipe) from bottom of the tank to its open ended top. If the flush valve drain is 6 inches or taller the 400A valve should fit. Some toilet models not supported would be Flapperless, Low Boy 1 Piece Toilets and Side Entry Valves.
For best performance of your toilet, consider replacing the flapper along with the fill valve. To choose the right flapper, please view them at Fluidmaster Toilet Flappers.
