About Grizzly Backflow & Plumbing

Backflow Testing Company in Delaware Near Me

Delaware utilities in Delaware track backflow devices and send yearly notices under the state's drinking water rules from the Division of Public Health.

The coastal plain is flat and sandy, and many homes and farms rely on irrigation through summer. Winters bring enough freezing nights to crack an exposed PVB. Salt air near the beaches also wears on brass and fasteners. Grizzly Backflow & Plumbing connects Delaware owners with certified testers for annual backflow testing, PVB testing and backflow preventer replacement when a body is past repair. Call (833) 990-5874.

  • Certified backflow testers working in and around Delaware
  • RPZ, double check, PVB and fire line assemblies
  • Test reports filed with your water utility

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Delaware.

Talk to a person
How often does a backflow preventer need testing in Delaware?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
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.
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.
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.
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.
