Fluidmaster Leak Sentry Universal Toilet Fill Valve - 400LS

Fluidmaster Leak Sentry Universal Toilet Fill Valve - 400LS

Refills the toilet tank after flushing. A worn valve may cause slow refill, continuous running, or water that does not shut off. Confirm this is the correct valve design for your tank before replacing it.

Fitment: Universal adjustable tank fill valve with Leak Sentry water-saving feature. Confirm tank configuration and follow the supplied instructions.

Service and installation: Shut off the toilet water supply before service. Flush the toilet and remove remaining tank water when working inside the tank. Follow the product instructions, avoid overtightening plastic fittings, and check for leaks and proper flushing after installation. Use a qualified plumber for uncertain fitment or installation.

How to find your model number: Check inside or under the toilet tank lid, on the tank's inside wall, or on the bowl or inside the tank area; label locations vary by manufacturer. Record every letter and number, then match it to the original part number or manufacturer parts diagram.
