Want Us To Inspect Your Backflow Preventer ?


Backflow prevention is an engineering discipline specializing in averting the flow of undesirable, often toxic or unsanitary water, in a plumbing system where it can potentially contaminate the drinking water supply. Our Reputation has been built protecting your water, Keeping Drinking Water Safe.


Backflow is the backward flow of water through a pipe. The normal direction of water flow is from the utility water main to homes or businesses. The backflow of water from a home plumbing system into community drinking water happens when water is pulled backward due to a pressure loss in the utility main pipe or pushed back by a pressure source like a well pump.

Backflow Prevention Backflow devices are mechanical plumbing devices installed in a plumbing system to prevent water from flowing backwards and contaminating the public water system. A properly tested and maintained backflow device can prevent the backflow of water of an unknown quality from backflowing into the community water system. NFPA 25, Authority Having Jurisdiction (AHJ) and your municipality’s water works department require that backflow devices be tested once a year.

Backflow Prevention Keeps Our Water Safe

NFPA 25, Authority Having Jurisdiction (AHJ) and your municipality’s water works department require annual inspection and testing of backflow prevention assemblies by a licensed tester to prevent the entrance of toxic or hazardous substances into the water supplies.

They are installed on a variety of water supply lines, including domestic water supply, sprinkler/standpipe systems, HVAC units, boilers and irrigation systems. While preventing contaminated or toxic water from flowing backwards into a municipality’s water distribution network, they may also prevent your sprinkler system from achieving full water flow demand.
