A hidden leak in Carrboro usually turns up as an OWASA bill that won't come back down, a meter that moves with the water off, or moisture with no obvious source. A plumber can test the supply lines and find the leak with minimal damage. Call the number on this page to be connected with a local plumber in Carrboro.
The Carrboro picture
Carrboro's homes are a mix: the historic mill houses near downtown, a large wave of 1980s construction and plenty of 1990s and 2000s neighborhoods. The median home was built in 1988, and about 29% went up before 1980. Older mill houses can have galvanized or patched supply lines and crawl spaces with tight access, while newer houses more often leak at plastic fittings, fixture supplies and appliance connections.
Water and sewer come from OWASA, which treats water at its Jones Ferry Road plant. OWASA calls the pipe from its system to your home your private service line, so that run is the owner's responsibility, though the exact split point isn't stated. A wet patch right at the meter box is worth reporting to OWASA first. OWASA's inventory found no lead service lines in its area.
Testing methods compared
| Method | What it shows | Best for |
|---|---|---|
| Meter test | Whether any water is leaving with fixtures off | First step for every OWASA home |
| Isolation and pressure test | Which part of the system is losing pressure | Narrowing the search to one branch |
| Acoustic listening | The sound of water escaping a pressurized pipe | Leaks under floors or in the yard |
| Thermal imaging | Temperature differences behind surfaces | Hot water lines in walls or slabs |
| Visual crawl space check | Drips, stains and wet insulation | Older raised-floor homes |
Signs it's time to call
- The OWASA bill jumps and stays high
- You hear water moving in a wall when everything is off
- Paint blistering near a shower or along a baseboard
- The irrigation zone near the street stays muddy
- A toilet refills by itself every so often
Timing notes
Irrigation season is a common time for leaks to surface in Carrboro, because a cracked lateral or valve can run for weeks. OWASA requires homes with irrigation or a pool to have a backflow device tested every year by an OWASA-certified tester, and that visit is a good moment to have the system checked for leaks too. Winter freezes are the other peak, especially in older houses with exposed crawl space piping. If the repair needs a permit, it goes through the Town of Carrboro's PIPER portal, and some nearby addresses actually fall under Orange County or Chapel Hill, so check the property's jurisdiction first.
