The team at Cascadia Backflow is trained and licensed to install, test, repair and provide documented backflow certification for all types of backflow prevention devices.  We will manage all aspects of the testing for you; our technician will complete the inspection paperwork and submit it directly to your appropriate water authority.


In the event your unit fails the testing, your technician will outline your options to repair or replace the unit so that it complies with the local requirements.


Before you hire a company to test your backflow devices, be sure they are trained to test and repair the backflow units.  Not all companies are trained to test and repair backflow devices!  You can rest assured that the technicians from Cascadia Backflow can test & repair your backflow device.
