Backflow prevention devices protect your home's drinking water from contamination if pressure in the municipal supply drops, and most Oregon water providers require annual certified testing to keep them compliant. We test the assembly, file the certified report directly with your provider, and repair or replace the device on the spot if it fails. In St. Johns (97203), winter cold snaps regularly catch exposed supply lines in crawlspaces and garages in this area off guard, leading to a spike in frozen-pipe calls.
