You may think that the water that comes out of your faucet only runs in one direction. But, the fact is, it is possible for water to run backwards in the pipes if the water pressure drops for some reason. The most common reasons for a drop in pressure is frozen pipes, broken water mains or high, unexpected demands for water. Because of this, many municipalities require backflow prevention devices to protect potable water from pollution or contamination.
Because mechanical backflow devices are made up of check valves and relief valves, they are prone to failure. Performing an annual test on the device makes sure that the valves are operating in the correct manner and pressure.
Our Michigan Backflow Testing plumbers have the necessary training, license and testing equipment to test and repair backflow devices as well as submit paperwork to your municipality for you.
