Annual Backflow Testing in Mckeesport, PA
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 Mckeesport, PA 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 Mckeesport, PA.
