As part of our service, Greenway handles all the necessary paperwork related to your annual inspection, then we will remind you when your next annual backflow test is due so your property remains in good standing with the local water authority.
Understanding the Backflow Preventer
The backflow preventer is the most critical component of an underground sprinkler system. This heavy, brass valve prevents water and any potential contaminants in the irrigation system from flowing backwards into the public water supply or well. Local government agencies responsible for protecting our drinking water manage a process for regularly inspecting, testing and certifying every backflow preventer in their jurisdiction.
Potable (clean) water flows under pressure through municipal water lines to homes and businesses. Backflow occurs when the water pressure in the municipal distribution system falls below the pressure in the residence or irrigation system. This siphoning effect can be caused by the use of fire hydrants, water main breaks, high usage or back pressure from a pump. The backflow preventer is designed with two check valves that only allow water to travel in one direction, thereby eliminating the possibility of backflow.
Backflow testing and certification can only be performed by a Certified Backflow Prevention Assembly Technician using special equipment that must be professionally calibrated each year.
What is the Testing Process?
It’s very simple and quick. We shut off the water supply, examine your backflow device and make sure there is no cross contamination. If there is, we’ve got the tools to fix the issue right there and get you certified.
