What is a backflow preventer?

A domestic backflow preventer is a device that prevents the water from your building backflowing into the public water supply. The City of Philadelphia requires all commercial businesses to have a backflow preventer installed and to have the device tested and certified annually.  In addition to a domestic backflow, some buildings also have a fire/sprinkler backflow preventer. We are not certifed to test fire/sprinkler backflow devices, but we can point you in the right direction if needed.
