Backflow Device Testing

What is a backflow device?

A backflow device protects your water supply. It keeps untreated water (water with chemicals, or water from uncontrolled sources like lakes and rivers) from contaminating the water in your home. Water is normally under a considerable amount of pressure to allow it to come from the faucet or showerhead with a decent amount of force. Occasionally, pressure can fail, say if a water main bursts, pipes freeze in the winter. When the pressure inside the pipe is suddenly reduced water may flow back into it from other sources, thus contaminating the entire system. This is why you’ll hear about “boil orders” after water main breaks. They want to make sure no one ingests anything that will make them sick.

What Causes Backflow?

Back pressure can even come from less dramatic sources like pumps in the water system, or even power washing equipment. To prevent any instances of backflow, a backflow preventer can be installed. A typical backflow device has several parts (test cocks and shut-off valves) that must be tested each year. In the U.S., the EPA ensures that the water supply companies keep their water safe. Many states require backflow testing annually. There are several cross-connections in residential plumbing that should be checked.

  • Laundry Sinks
  • Outdoor Faucets
  • Lawn Irrigation Systems
