According to Washington law, backflow assemblies are required to be tested at the time of installation and annually after installation.
WAC 246-292-050(3) Owners shall ensure that a backflow assembly tester (BAT) is responsible for inspecting, testing, and monitoring backflow prevention assemblies in accordance with WAC 246-290-490.
I Inspect, Test, and Monitor Backflow prevention assemblies in accordance with the requirements of WAC 246-290-490(7)
In the event that a backflow assembly needs to be repaired my Contractors License REDWOB*933PU allows me to provide that service.
I am certified to test backflow assemblies in the State of Washington. Annually I provide updated information to each water district which allows me to remain on their list of approved backflow testers.
If you would like to make the annual re-certification of your backflow assembly more of an automatic process, I would be pleased to add you to the Redwood Backflow annual maintenance program.
