About Grizzly Backflow & Plumbing

Backflow Testing Company in Saint Helena, 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 Saint Helena, 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.

Backflow testing FAQs

Questions about backflow testing

Questions Saint Helena, CA property owners ask about backflow testing and backflow prevention.

Talk to a person
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
What is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
Can a backflow preventer freeze?
Yes. Trapped water expands and can crack the bronze body or blow out the bonnet. Insulated enclosures, heat cable or draining the device for winter prevent it.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
Is fire sprinkler backflow testing different?
Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
