A sprinkler system backflow valve usually sits between your home’s main water supply connection and your sprinkler system.  The purpose is to prevent the backwards flow of water which can pollute the potable water supply with contaminants.

Pollutants from the gardening area, or lawn area, can flow back into the city’s water supply if a sprinkler system backflow valve is not used.  Because of the importance of this valve, it is necessary that all sprinkler system backflow valves be inspected once each year and necessary repairs be made to it immediately.

City Backflow Testing is licensed and certified to work on all sprinkler system backflow valves.
