Above Ground (RPZ) Backflow Preventers

Hynds Water support quality brands of backflow preventers for both above and below ground applications. They can be supplied on their own, complete with fittings or as part of a manifold or standpipe configuration. Repair kits and Accessories are available.

High hazard applications require RPZ (reduced pressure zone) backflow preventers. In cases where back siphonage (or backpressure) exists, the contaminated water will visibly flush out the bottom of the RPZ, reducing pressure.
