Devices we service

Every common backflow preventer, every major brand.

If you have it installed, we can test it, repair it, or replace it. Here's a quick guide to the device types we work with daily across South Florida.

Device types

Backflow assemblies are matched to the hazard level of what's downstream. Here are the five most common types you'll see in Florida.

RPZ

Reduced Pressure Zone Assembly

High-hazard applications: irrigation with chemicals, boilers, processing.

Two independent check valves separated by a relief valve. The highest level of protection — required wherever contamination could harm potable water.

DCDA

Double Check Detector Assembly

Fire suppression lines with meter bypass for leak detection.

Two checks plus a metered bypass that catches small leaks or unauthorized water use on fire systems.

DC

Double Check Valve Assembly

Low-hazard cross connections such as commercial heating loops.

Two spring-loaded check valves in series. Used where the substance is non-toxic but still undesirable in the drinking supply.

PVB

Pressure Vacuum Breaker

Residential and commercial irrigation, low-hazard.

Single check with an air inlet. Must be installed at least 12″ above the highest downstream outlet. Cannot be subjected to back-pressure.

SVB

Spill-Resistant Vacuum Breaker

Indoor low-hazard applications where spillage is unacceptable.

Similar to a PVB but with a spill-resistant design for indoor installations.
