Backflow Services in Carrboro, NC

Any Carrboro property that draws OWASA water and also has irrigation, a fire line, or certain commercial fixtures needs a backflow assembly — the device that stops used or contaminated water from siphoning back into the public supply. We handle that assembly’s whole lifecycle: annual testing, repairs when it fails, replacement when it’s past saving, and freeze-protective enclosures. From Lake Hogan Farms to the storefronts near Weaver Street, we keep Carrboro’s drinking water protected and the paperwork filed with OWASA.

Backflow happens when pressure in your line drops or spikes and water reverses direction, pulling whatever is downstream — fertilizer, stagnant irrigation water, chemicals — back toward the clean supply. A backflow preventer is the one-way gate that stops it. Because Carrboro and Chapel Hill share OWASA’s community-owned system, a single failed device on one property is a risk the whole neighborhood inherits.

Whole-property coverage on one visit

We handle the full lifecycle where we can: annual testing, repair when a check valve or relief valve fails, full replacement when an assembly is past saving, and freeze-rated enclosures for the devices sitting out in the open. Our team is local to Chapel Hill, certified, and insured, and we keep the OWASA paperwork off your plate — we report test and repair results to the authority for you.

Carrboro’s water comes from OWASA — the Orange Water and Sewer Authority — the community-owned utility serving both Carrboro and Chapel Hill. OWASA runs the cross-connection control program that protects the shared drinking-water supply, and that program is why backflow testing isn’t optional here.

By default, OWASA requires annual testing of backflow assemblies by a certified tester. There’s one common exception: irrigation systems with no chemical feed and no booster pump may qualify for testing every three years instead. We confirm which schedule applies to your specific setup before we file anything.

After we test or repair an assembly, the certified tester reports those results to OWASA within 10 business days. You don’t have to chase down forms or deadlines — we handle the documentation and make sure your property stays in good standing with the authority.
