Backflow Testing in Memphis

Backflow Testing by a Certified Professional for Memphis Irrigation Systems

Irrigation backflow testing checks the assembly that separates landscape water from the potable water supply. If water reverses direction, soil, fertilizer, pesticides, and other substances from the irrigation system could enter a drinking water line. We provide testing performed by a certified professional for residential and commercial irrigation customers in Memphis.

Testing measures how the prevention assembly responds under specific pressure conditions and determines whether its internal components are operating as intended. A properly functioning device helps keep irrigation water where it belongs.

Request irrigation backflow testing by calling (901) 657-3614. Have the property address and any notice from your water provider available when you contact us.

What an Irrigation Backflow Test Checks

Backflow occurs when water moves through a plumbing system in the opposite direction from its intended flow. It can result from backpressure, when downstream pressure exceeds supply pressure, or backsiphonage, when a drop in supply pressure creates a vacuum-like effect.

A backflow prevention assembly contains valves and other components designed to stop this reverse movement. A standard test generally includes a visual inspection, calibrated test equipment, pressure measurements, and documentation of the results.

Testing can identify conditions such as:

• Visible damage or deterioration affecting the assembly
• Leaks around valves, fittings, or test connections
• Pressure readings outside accepted test criteria
• Internal components that don’t open, close, or hold pressure as intended

If an assembly doesn’t pass, it generally requires correction and retesting before it can be considered compliant. The appropriate next steps depend on the device, its condition, and the property’s water provider.

Testing for Residential & Commercial Irrigation Systems

Backflow testing is part of our broader irrigation services for Greater Memphis properties. Our capabilities include system design and installation, spring turn-on and preparation, repairs and component upgrades, winterization, and backflow testing. We also offer water-conservation options such as rain sensors and Wi-Fi-enabled controllers.

Residential systems may serve lawns, planting beds, and other landscaped areas. Commercial systems can involve larger zones, multiple controllers, and more complex layouts. In either setting, the test evaluates the performance of the installed prevention assembly.

Preparing for the Test

Before requesting service, gather the property address, any testing notice from the water provider, and previous test documentation, if available. These details can help identify the assembly and clarify whether the provider requires specific forms or procedures.

Understanding the Results

Test documentation records information about the assembly and its measured performance. Accepted testers, required forms, submission procedures, and follow-up steps vary by water provider. Confirm the current requirements for your account directly with the provider.

MLGW Cross-Connection Control Requirements

Memphis Light, Gas and Water maintains a Cross Connection Control Program for residential, commercial, and industrial customers whose systems may present a hazard to the potable water supply. A cross-connection is a physical connection through which non-potable water or other substances could enter the drinking water system.

MLGW states that affected customers must provide adequate protection and comply with applicable testing requirements. Noncompliance can result in interruption of water service. Procedures may differ by account and system type, so follow the instructions on your MLGW notice and confirm current requirements directly with the utility.

The Tennessee Cross-Connection Control Manual states that backflow prevention assemblies should be tested at least every 12 months. Local deadlines, accepted testers, documentation, and submission procedures are determined by the applicable water provider. If you received a provider notice, use the date listed there to guide scheduling.
