Cross-Connection Survey in Dickson, TN

A cross-connection survey is a walk through your property looking for places where potable water piping meets something it should not: a hose left in a mop sink, a boiler fill line, a chemical feeder, a pond fill, a irrigation zone with fertilizer injection.

Each point gets classified by hazard. High hazard, meaning anything that could make someone sick, typically calls for an RPZ or an air gap. Low hazard, meaning pollutants that affect taste or color, can usually take a double check.

Water utilities order surveys for new commercial accounts, change of use and some renewals. Owners also ask for them before a purchase or a remodel, so they know what devices they will be required to install.

The result is a written list of each cross-connection, its hazard level and the device or fix it needs.

Grizzly Backflow & Plumbing connects Dickson, TN property owners with surveyors who know local backflow prevention rules and can follow up with installation and backflow testing. Call (833) 990-5874.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Cross-Connection Survey in Dickson, TN.

Talk to a person
What is the difference between an RPZ and a double check valve?
Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.
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.
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.
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.
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.
