Fluidmaster® 400A

Fluidmaster® recommends using the 400A fill valve in toilets that date prior to 1994 with flush volumes between 3.5 and 7 gallons per flush. Fluidmaster®'s 400A Universal Toilet Fill Valve is the #1 best-selling fill valve in the world! A universal design, with an adjustable height from 9" to 14" to fit most toilets. The 400A offers quick refill rates and replaces ballcocks and other toilet fill valves. A trusted and proven toilet fill valve, the 400A is built to last from corrosion-resistant materials for a long lifespan. This code approved, anti-siphon design, won't contaminate the fresh water supply. Some toilet models not supported: Glacier Bay® or Niagara® Flapperless Toilets, One Piece Toilets. Does not replace Side Entry Valves. Fluidmaster's late Founder invented the fill valve technology in 1958. For best performance of your toilet, consider replacing the flapper along with the fill valve.
