RPDAs are intended for use in continuous and non- continuous pressure installations, in back-siphonage and backpressure conditions. The RPDA is intended to provide protection in low and high hazard situations.

DCDAs are for use in both continuous and non- continuous pressure applications, in back-siphonage and backpressure conditions. The DCDA is intended to provide protection in low hazard situations only.

RPs are used for continuous and non-continuous pressure applications, in back-siphonage and backpressure conditions. The RP is intended to provide protection in low and high hazard situations.

Dual Checks are designed for use in low hazard applications where a fully approved, testable backflow preventer is not required. Check with the local authority having jurisdiction for acceptance.

A device containing a float-check, a check seat and an air inlet port. For both low and high hazard applications, AVBs are intended for use in a non- continuous pressure application (no more than 12 hours of pressure per 24 hour period), in a back- siphonage condition only.
