Cross-Connection Survey in Hanover, MD

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 Hanover, MD 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 Hanover, MD.

Talk to a person
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.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
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.
How much does backflow testing cost in Hanover, MD?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Hanover, MD.
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.
