The BRASSCRAFT ps2159 is a time-rated vinyl toilet flapper designed to replace worn or leaking flappers in residential toilet tanks. It includes replaceable baffles that allow the installer to adjust water consumption per flush cycle, helping to reduce water waste without a full fixture replacement. The vinyl construction resists chlorine degradation common in treated municipal water supplies. This flapper ships carded and ready for installation, making it a practical service-call item for plumbers handling residential toilet repairs.
The ps2159 is suited for residential plumbing applications where a standard flapper has failed or is causing a running toilet. The adjustable baffle system allows water volume per flush to be dialed in after installation, which is useful in retrofits where the toilet valve and bowl are already balanced for a specific flush volume. The universal fit design broadens its range of use across common residential toilet tanks.
Designed as a universal-fit replacement flapper for standard residential toilet tanks. No specific model or brand compatibility data was provided by the manufacturer for this SKU.
A licensed plumber or experienced DIYer can install this flapper. Before service, shut off the supply stop valve behind or below the toilet and flush to drain the tank. Disconnect and remove the old flapper from the overflow tube ears and lift chain, then seat the ps2159 onto the flush valve and attach the chain with appropriate slack. Select the correct baffle insert for the desired flush volume before completing the installation.
