Backflow Testing & Cross-connection Q&A

What is a backflow prevention device?

A backflow prevention device is a mechanical valve installed on water service lines (or at plumbing fixtures) to prevent backflow of contaminants into drinking water. Both residential and commercial property owners will have these valves. A property can have multiple valves.

What is my responsibility?

Washington State requires that backflow valves must be tested by a Certified Backflow Assembly Tester every year to make sure they work properly. Failure to do so can result in fines and penalties.

What do I do next?

Call Coffey Refrigeration. We are a Department of Health(DOH)-certified backflow testing company.

What can I expect from Coffey Refrigeration?

Our Certified Backflow Assembly Tester will come out and test your backflow prevention valves. If a valve fails the test, we will repair and retest it. We then file all the paperwork required by the state of Washington.

We can place you on our worry-free automatic testing schedule at your request.
