Annual Backflow Testing in Northfield, VT

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 Northfield, VT 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 Northfield, VT.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Annual Backflow Testing in Northfield, VT.

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.
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 Northfield, VT 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.
Who sends the test report to the water utility?
The tester usually files it, either on the utility's paper form or through its online portal. Ask for a copy for your own records.
