New Jersey water systems run cross-connection programs under NJDEP rules, and utilities in New Jersey track devices on commercial, industrial and residential services.

Dense development means many buildings with fire lines, boiler feeds and process water, often in older properties. Winters freeze reliably, so outdoor devices need protection. Grizzly Backflow & Plumbing connects New Jersey property owners with certified testers for fire sprinkler backflow testing, commercial backflow testing and cross-connection surveys.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in New Jersey.

Talk to a person

What happens if I miss the backflow test deadline?

Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.

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.

Does my lawn sprinkler system in New Jersey 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.

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.

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.
