About Grizzly Backflow & Plumbing
Backflow Testing Company in Lagunitas, CA Near Me
California's cross-connection rules, long known as Title 17 and now set by the State Water Resources Control Board, require water suppliers in Lagunitas, CA to keep a list of every backflow assembly and collect a passing test each year.
Many utilities accept reports only from testers certified by an approved body such as the AWWA California-Nevada Section. Recycled water lines add another layer: sites with purple pipe often need an RPZ on the potable service.
