Backflow testing in Connecticut runs through your water utility's cross-connection program under Connecticut Department of Public Health rules. Commercial buildings and fire lines make up a large share of the testable devices here.

Connecticut winters bring frost well below grade, so most assemblies sit inside basements and riser rooms. Older industrial buildings often have cross-connections nobody has mapped. Grizzly Backflow & Plumbing connects Connecticut property owners with certified testers for commercial backflow testing, fire sprinkler backflow testing and cross-connection surveys. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Connecticut.

Talk to a person

Why is water dripping from my RPZ relief valve?

A steady drip usually means debris is holding the first check open or the relief valve diaphragm is worn. A cleaning or a rebuild kit fixes most cases.

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.

Will my water be off during the test?

Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.

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.

Is fire sprinkler backflow testing different?

Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
