Cross-Connection Survey in Houston, TX

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 Houston, TX 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 Houston, TX.

Talk to a person
How often does a backflow preventer need testing in Houston, TX?
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.
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
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.
