Fluidmaster 5401LA Toilet Flapper Cato

Product Description

The FLUIDMASTER 5401LA is a toilet flapper designed as a direct replacement for Cato toilet models. The flapper is the sealing component inside the tank that controls water flow from the tank into the bowl during each flush cycle. When a flapper wears out or warps, it allows a continuous leak past the flush valve seat, wasting water and causing the fill valve to cycle repeatedly. This part is installed by plumbers and experienced DIYers performing routine toilet repair. At 0.4 pounds, it is a lightweight, easy-to-handle component suited for standard residential toilet service.

This flapper is intended for use in residential toilet tank assemblies compatible with Cato fixtures. It fits into the standard flush valve seat configuration found in these toilets and is sold individually. Typical installation scenarios include routine maintenance calls, leak diagnostics, or water-conservation upgrades where the existing flapper has degraded, hardened, or begun to pass water continuously.

Installation Notes

Installation is performed by a licensed plumber or qualified DIYer following standard toilet repair procedures. Shut off the water supply at the stop valve behind or beneath the toilet and flush to drain the tank before beginning work. Remove the old flapper from the flush valve ears and disconnect the chain from the flush lever before installing the new unit. Verify the chain length allows full flapper lift without binding or preventing a complete seal at rest.
