Annual Backflow Testing in Minneapolis, MN

Your water utility mailed a notice. It names a device, a serial number and a due date. That letter is the start of annual backflow testing, and Grizzly Backflow & Plumbing connects you with a local tester in Minneapolis, MN who can handle it.

The tester closes the downstream shutoff, hooks a differential pressure gauge to the test cocks and reads each check valve in turn. On a double check, each check has to hold at least 1.0 psid. On an RPZ, the relief valve has to open at no less than 2.0 psid. The numbers go on the report exactly as read.

Most residential tests take about half an hour, and your water is off for part of it. Commercial assemblies take longer, especially 4 inch and larger devices.

If the device passes, the report gets filed. If it fails, you get the reason in plain words and the options: repair, rebuild or replace.

Backflow prevention only works when the device is checked on schedule. Call Grizzly Backflow & Plumbing at (833) 990-5874 to book your test in Minneapolis, MN.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Annual Backflow Testing in Minneapolis, MN.

Talk to a person
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
Does my lawn sprinkler system in Minneapolis, MN 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.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
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.
