Annual Backflow Testing in Waxhaw, NC

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 Waxhaw, NC 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 Waxhaw, NC.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Annual Backflow Testing in Waxhaw, NC.

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.
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.
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.
How much does backflow testing cost in Waxhaw, NC?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Waxhaw, NC.
