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 Quickly replace inefficient; outdated and leaky toilet fill valves with this water-saving design.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.
