Tapco 51226-RP Ballcock Plunger

Product Description

The TAPCO 51226-RP is a ballcock plunger used in toilet fill valve assemblies to control water flow into the tank. The plunger seats inside the ballcock body and opens or closes the water inlet based on float position. When the float drops as the tank empties, the plunger lifts to allow water in. When the tank reaches the set level, the float rises and forces the plunger closed, stopping flow. This part is typically installed by plumbers during ballcock repair or rebuild service on residential toilets.

The 51226-RP is suited for ballcock fill valve repair applications in residential toilet tanks. It is used when the existing plunger has worn, cracked, or lost its seal, causing continuous running or improper fill cycles. Installation requires shutting off the water supply, draining the tank, and disassembling the ballcock body to access and replace the plunger. Confirm the plunger dimensions and body type before installation to ensure proper fit within the existing valve assembly.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply at the stop valve and flush the toilet to drain the tank before disassembly.

Follow applicable local plumbing codes and IPC guidelines for residential fixture repair.
