PROTECTING RPZS

When it comes to protecting your backflow assembly, there’s a right way and a wrong way. Choosing the right way means offering the most complete protection you can provide your water supply and your employees. Installing your backflow prevention assembly improperly exposes it to unnecessary flooding risks. Here’s why:

PROTECT WHAT PROTECTS: THE IMPORTANCE OF SECURING YOUR RPZ

Any commercial or industrial facility can use any amount of water, but once used water passes through a meter and backflow preventer, it cannot go back into the water supply.

A reduced pressure zone (RPZ) valve assembly provides exceptional safeguards because it has a relief valve built into the assembly. When under threat of a backflow event, the relief opens up, dumping water that would have otherwise recirculated into the water supply.

RPZ VALVE ASSEMBLY

RPZ valve assemblies provide the highest level of protection for your water supply.

There is one critical difference between an RPZ and a double-check (DC) valve: RPZs are designed to dump water to protect the water system.

An RPZ uses two independently operating check valves, just like the DC valve assembly. But the RPZ is also equipped with a hydraulic differential relief valve located below the first check valve.

This hydraulic valve (and its strategic placement) makes the RPZ virtually fail-safe: when the pressure zone is compromised, the relief valve is triggered and opens, expelling water. Since it is impossible for contaminants to backflow through an RPZ, they are trusted for maximum protection of the water supply.

RPZ ENCLOSURES PROTECT YOUR INVESTMENT

RPZ valve covers provide the best barrier between backflow and your water supply. As such, they deserve the highest possible level of protection. When working properly, a RPZ will flood the surrounding area, so an RPZ is better off in a dedicated enclosure outside a building in order that excess water can flow away from your property and critical equipment.

In fact, RPZs offer such peace of mind that many jurisdictions now require their installation on all domestic and fire service lines. And when it comes to installing an RPZ, you have two options: inside in a mechanical room, which exposes you to unnecessary flooding risks, or in an RPZ enclosure.

If you are an architect or design engineer, you want your projects to benefit from prudent and practical decision making. So don’t take the risk of installing an RPZ inside a building, where it can damage property and put people’s lives and livelihood at risk. Moving the RPZ outside and protecting it with an above-ground RPZ enclosure is the best option.
