Backflow Preventer Installation in Seattle, WA

A backflow preventer installation starts with one question: what is the hazard? Your water purveyor or local code decides whether you need an RPZ, a double check, a PVB or a spill-resistant vacuum breaker.

Grizzly Backflow & Plumbing connects you with plumbers in Seattle, WA who size the device to the line, set it at the right height and leave clearance for testing. An RPZ needs space under the relief port and a drain that can take a full discharge. A PVB needs 12 inches of rise above the highest outlet. A DCVA needs test cocks you can reach with a gauge.

Most utilities want the device tested within days of installation, and some will not close a permit until that first report is filed. Plan for it.

Permits, unions on both sides and a strainer upstream on dirty water systems are worth asking about. A strainer is cheap compared to rebuilding checks every year.

Call (833) 990-5874 to get a backflow preventer installed correctly in Seattle, WA, with backflow testing done right after.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Backflow Preventer Installation in Seattle, WA.

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.
Does my lawn sprinkler system in Seattle, WA need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
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.
How much does backflow testing cost in Seattle, WA?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Seattle, WA.
