Backflow Testing in Chattanooga & North Georgia
Protect Your Water Supply and Stay Compliant
A backflow preventer is a valve assembly that keeps water from flowing backward into the public water supply. Without one, a sudden pressure drop, such as a water main break or heavy firefighting demand, can pull water from irrigation lines, boilers or other connections back into the drinking water system.
Properties with lawn irrigation, fire sprinklers, boilers and many commercial connections are typically required to have a backflow assembly, and many water utilities require it to be tested regularly. Over time, internal checks, springs and seals wear and the device can fail without any visible sign.
Metro tests backflow assemblies, explains the results, repairs or rebuilds devices that fail and installs new assemblies where they're needed.

Signs You Need Backflow Testing
Your Utility Sent a Test Notice
Many utilities mail annual testing notices. Don't let the deadline pass.
You Have an Irrigation System
Sprinkler and irrigation connections typically require a backflow preventer.
Device Is Leaking or Discharging
Water dripping or spraying from the assembly or relief valve means internal parts need attention.
Discolored Water After Pressure Loss
Cloudy, discolored or odd-smelling water after a pressure event should be checked immediately.
No Test in Over a Year
Assemblies that haven't been tested in over a year may have worn checks or seals.

What Affects the Cost of Backflow Testing?
Backflow costs depend on the type and size of the assembly, how many devices are on the property, and whether the device passes its test or needs repair or replacement. Testing alone is a routine visit; rebuilding a failed assembly or installing a new device for an irrigation system, fire line or commercial connection involves more parts and labor.
We explain the results of every test and give you an upfront price for any repairs before we start.
You always get the price before any work begins. Financing is available for qualified customers on larger jobs.
Expert Tip From Metro's Master-Certified Team
Protect It Before a Freeze
Above-ground backflow assemblies on irrigation systems can crack in a hard freeze. Before the first cold snap, shut off and drain your irrigation system and insulate the assembly with a fitted cover. A cracked body is far more expensive than a winter cover.

Frequently Asked Questions

(423) 855-0967What is backflow?
Backflow is when water flows backward from a property into the public drinking water supply, which can happen during a pressure drop. A backflow preventer stops that from happening.
Who needs a backflow preventer?
Common examples include irrigation and sprinkler systems, fire sprinkler lines, boilers and many commercial properties. Your water utility can confirm whether your property requires one.
How often does a backflow device need testing?
Many water utilities require annual testing of backflow assemblies. Check the notice from your utility for your specific deadline and requirements.
What happens if my device fails the test?
We repair or rebuild the assembly with replacement parts, or replace it if it's beyond repair, then retest to confirm it passes.
Can you install a new backflow preventer?
Yes. We install new backflow assemblies for irrigation systems and other connections that require them.
Do you handle reporting to the water utility?
Many utilities require test results to be submitted. Ask us about handling the paperwork when you book.
