How to Install Fluidmaster's 400LS LEAK SENTRY® Toilet Fill Valve
Fluidmaster® recommends using the 400LS fill valve in toilets that date prior to 1994 with flush volumes between 7 gallons per flush and 3.5 gallons 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.
