Backflow testing FAQs

Questions about backflow testing

Questions Marydel, DE property owners ask about backflow testing and backflow prevention.

Talk to a person
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.
Does my lawn sprinkler system in Marydel, DE 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.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
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.
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.
