The Team You Know, The Quality You Trust


With over 15 years experience and thousands of customers statewide, Backflows Northwest has established itself as the largest backflow testing company in Washington. While we are headquartered on the Eastside of Puget Sound, we maintain regional coverage statewide by hiring local technicians. The technician assigned to test your property most likely doesn’t just work in your area, they live there too. Our technicians are familiar with your area as well as with the statewide water districts. We can be your representative and point of contact to handle logistics and communications with water purveyors. Electronically filing all the paperwork with your purveyor is part of our excellent service.
