At Backflows Northwest we understand that an annual test does not need to be a complicated event. Once you send us your information we will contact you to confirm the time, price and any special circumstances. Provided no additional repairs are needed, your test results will be sent to the appropriate water purveyor (company/department) and you will receive your invoice. It’s that easy!
