New Jersey state laws mandate that backflow preventers be tested annually. Custom Landscaping and Lawncare is recognized and certified by the NJDEP as a licensed and certified backflow tester.
Annual testing of your backflow preventer greatly reduces a cross connection or contamination of your drinking water.
What is a cross-connection?
A cross-connection is any temporary or permanent connection between a public water system or consumer’s potable (i.e., drinking) water system and any source or system containing non-potable water or other substances. An example is the piping between a public water system or consumer’s potable water system and an auxiliary water system, cooling system, or irrigation system.
What is a backflow preventer?
A backflow preventer is a means of mechanism to prevent backflow. The basic means of preventing backflow is an air gap, which either eliminates a cross-connection or provides a barrier to backflow. The basic mechanism for preventing backflow is a mechanical backflow preventer, which provides a physical barrier to backflow. The principal types of mechanical backflow preventers are the reduced-pressure principle assembly, the pressure vacuum breaker assembly, and the double check valve assembly. A secondary type of mechanical backflow preventer is the residential dual check valve.
What is a pressure vacuum breaker (PVB) assembly?
A PVB assembly is a mechanical preventer that consists of an independently acting, spring-loaded check valve and an independently acting, spring-loaded, air inlet valve on the discharge side of the check valve. It includes shutoff valves at each end of the assembly and is equipped with test cocks. A PVB may be used to isolate non-health hazards, but is effective against backsiphonage only.
How much will the test cost?
The price of testing the backflow preventer varies according to the size of the backflow preventer. Sizes range anywhere from 3/4″ – 1.5″. Please call our office to inquire about pricing.
