Apollo 40004A4 Backflow Preventer Repair Kit

Repair kit for 40204T2 backflow preventers

This Apollo 40004A4 kit supplies the replacement components needed to service a 40204T2 backflow preventer. It is intended for plumbing professionals and facility maintenance teams who must keep cross-connection control assemblies in compliance. The package contains the specific internal parts designated for that model.

Fits directly into the 40204T2 valve body

Installation requires access to the existing 40204T2 assembly and standard plumbing hand tools. No additional fittings or adapters are included because the components are sized for that exact housing. Using this kit restores the preventer’s sealing surfaces without replacing the entire valve body, saving material cost and system downtime.

Maintains sealing performance over repeated cycles

The supplied elastomers and hardware are manufactured to the same specifications as the original equipment. Under continuous pressure differentials and frequent flow reversals, the replacement seats and discs resist deformation and mineral buildup. Regular inspection intervals remain unchanged after the repair is completed.
