Fluidmaster LEAK SENTRY 400LS Fill Valve, 9 to 14 in, Plastic
Fluidmaster? recommends using the 400LS fill valve in toilets that date prior to 1994 with flush volumes between 7 gal per flush and 3.5 gal per flush. The 400LS LEAK SENTRY? universal water-saving toilet fill valve has all the same benefits of the 400A fill valve, plus it comes with leak prevention technology and a water-saving roller clamp. Leak prevention technology stops the automatic refill of the toilet tank due to a worn or faulty flapper. The included roller clamp allows you to regulate the amount of water refilling the toilet bowl for maximum efficiency. Quickly replace inefficient, outdated and leaky toilet fill valves with this water-saving design. The 400LS 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.
