About Grizzly Backflow & Plumbing

Backflow Testing Company in Hollister, 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 Hollister, 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. Grizzly Backflow & Plumbing connects Hollister, CA property owners with certified testers for annual backflow testing, RPZ valve testing and test report filing. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

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

Talk to a person
How often does a backflow preventer need testing in Hollister, CA?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
What happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.
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.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
