To download our free guide to fix common toilet problems please click here: Fluidmaster Toilet Repair Guide

Read More
Fluidmaster® recommends the PerforMAX® fill valve for toilets manufactured from 1994 to the current time (works on older toilets). If you are replacing the fill valve, we recommend you also replace the flapper with the 502 flapper for the best performance. The 502 flapper works on both old and new 2 inch flush valve toilets.

The most powerful toilet fill valve on the market. The 400AH is also known as the 400ARHR. With efficient and ultra-quite fill the 400AH replaces other inefficient, or outdated fill valve designs. Help prevent excessive or inadequate bowl fill levels. The 400AH is a code approved, anti-siphon design, that 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.
