## Description

00A 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.

Review: Excellent Product - I have two bathrooms and both of the flush valves suffered from the same issue. They would not stop running. I received a replacement for one of them under warranty and the replacement was one of this model. It worked perfectly so I decided to order TWO more of the exact same model. One in a spare and the other was installed in my second bath room. Could not be happier with the installation, and performance. I am 78 and the toilets are not easy to get to. But the installation was so simple that even I could do it.

### ⭐⭐⭐⭐⭐ Fixes that ghost toilet
*by B***Y on 26 June 2020*

We have three American Standard toilets and all had issues with water continuously running. I was going to bite the bullet and call a plumber when youtube came to the rescue. Watched a 10-min video, identified our toilets as being American Standard, and ordered these parts. Shipping was fast and install a breeze and success; no more running toilets. Life span is from 2-3 years so I purchased a few as spares.
