Every backflow preventer on a water service has to be tested by a certified tester, usually once a year, and the water district wants the report filed. The test itself is simple to describe: gauges get hooked to the test cocks, the assembly is isolated, and the tester reads whether the check valves and the relief valve still hold at the required pressure differential. Assemblies fail for boring reasons, mostly grit under a check seat or a tired rubber. A failed test is not a replacement, most units get rebuilt with a kit the same visit. The Otter Squad tests, repairs and replaces backflow assemblies for homes, irrigation systems and businesses around Livermore and the Tri-Valley. https://ottersquad.com/backflow-testing-livermore Book your annual test on (925) 397-2271. #backflowtesting #livermore #trivalley #watersafety #plumbing
