Cross-Connection Survey in Centennial, CO

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 Centennial, CO 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 Centennial, CO.

Talk to a person
How often does a backflow preventer need testing in Centennial, CO?
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.
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.
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.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
