Cross-Connection Survey in Olean, MO

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 Olean, MO 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 Olean, MO.

Talk to a person
How often does a backflow preventer need testing in Olean, MO?
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.
Does my lawn sprinkler system in Olean, MO 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.
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.
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.
