Flush Valve Vacuum Breaker Repair Kit

What is this?

This is a high-quality vacuum breaker repair kit designed for commercial flushometers. It contains the essential internal rubber and plastic components required to rebuild the vacuum breaker assembly, which is the vertical "tube" section located below the main flush valve body.

What does it do?

• Prevents Water Contamination: The vacuum breaker acts as a one-way check valve. It allows air to enter the plumbing line when the flush cycle ends, breaking the vacuum and preventing "back-siphonage" (contaminated water being sucked back into the clean water supply).

• Stops External Leaks: If you notice water leaking from the bottom of the flush valve or spraying out from the vacuum breaker tube during a flush, the internal "duckbill" or sleeve has likely failed. This kit replaces those seals to ensure a watertight operation.

• Reduces Noise: Worn-out vacuum breaker components can cause whistling or vibrating sounds during the flush cycle. Installing this kit restores quiet, smooth performance.

• Ensures Code Compliance: Maintaining a functional vacuum breaker is a critical health code requirement for commercial restrooms to protect the building's potable water.

Will it fit my needs?

This kit is compatible with most standard commercial flush valves used for toilets and urinals. It is the industry-standard "V-551-A" style repair assembly. If your valve is a manual diaphragm type and you are experiencing leaks specifically at the connection between the valve and the fixture, this is the correct repair solution.
