Apollo Valves CON-40004A4 Backflow Preventer Repair Kit

Product Description

The APOLLO VALVES CON-40004A4 is a repair kit designed for backflow preventers used in plumbing and water distribution systems. The kit restores proper function to a worn or failed backflow preventer by supplying the critical internal components most likely to degrade over time. Contents include O-rings, a seat, a diaphragm relief valve, a seat disc, and an instruction sheet. Licensed plumbers and water system technicians install this kit during scheduled maintenance or in response to a failed backflow test. It is a direct-from-manufacturer kit, ensuring components meet the original design specifications of the host assembly.

This repair kit is intended for use with the APOLLO VALVES 40204T2 backflow preventer. It is also compatible with assemblies referenced by supplier designations 2ZXX9 and 2ZXY1. Typical applications include potable water supply lines, irrigation backflow assemblies, and commercial plumbing systems where backflow prevention is required by code. The kit is suited for both residential and light commercial service calls where component-level repair is preferred over full assembly replacement.
