The Team You Know, The Quality You Trust


With over 15 years experience and thousands of customers statewide, Backflows Northwest has established itself as one of the largest backflow testing companies in Washington. While we are headquartered in 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, but he or she live there too. Our technicians are familiar with your area as well as with the statewide water districts. All the paperwork is electronically filed with your water purveyor. We can be your representative and point of contact to help with all the logistics and communications dealing with water purveyors. Our new customer portal allows registered customers to check into their accounts, make payments, schedule work, and communicate with our friendly staff with the ease of a single login.
