Got a testing notice from your water utility? We test, repair and replace backflow preventers on irrigation, home and commercial water lines.
Available in: Norfolk, Winchester & Wilmington
Backflow preventers stop dirty water flowing back into the clean supply. Many utilities require them to be tested.
A backflow preventer is a valve assembly, often on an irrigation system, fire line or commercial water service. If pressure drops, it stops water that's been in contact with soil, chemicals or equipment from flowing back into the drinking water.
Powell's tests backflow assemblies and repairs or replaces them when they fail. Send us your utility's notice when you book, and your plumber will tell you exactly what's needed.

On most homes it's a brass or bronze valve assembly with two shut-off handles and small test ports, usually above ground near the irrigation system or where the water line enters the building.
