Close the main water shutoff right away, then open a low faucet to drain what is left in the lines. Once the water has stopped, a plumber cuts out the split section and joins in new pipe. Call the number on this page to be connected with a local plumber in Durham.

Stop the damage
- Close the main shutoff. Look where the supply pipe comes into the house: the crawl space, a garage wall, a utility room or beside the water heater. Turn it clockwise until it stops.
- Keep clear of wet electrical. Turn off breakers for soaked areas only if the panel is somewhere dry.
- Protect the water heater. If the hot side burst, switch off the heater's breaker or set a gas unit to pilot.
- Empty the pipes. Open the lowest faucet so the remaining water drains out there instead of through the break.
- Take pictures. Photograph the pipe and the damage before cleanup, which helps with an insurance claim.
Why pipes split
Freezing is the classic cause. When water in a pipe turns to ice, it expands and builds pressure in the section between the ice and the nearest closed fixture, and the pipe can rupture there rather than at the ice itself. Many breaks stay sealed by ice and only start leaking during the thaw. In Durham, pipes in crawl spaces, garages, exterior walls and outdoor spigots are most exposed during a hard freeze.
Other bursts have nothing to do with cold: a washing machine or toilet supply hose that fails, a corroded fitting, or a pipe worn through where it rubbed framing.
Is it your pipe or the City's?
A break inside the house is the owner's to repair. Outside, it is less clear-cut. Durham's 2024 water quality report shows the City owning the service line segment on the water main side and the owner owning the building-side plumbing, but the text does not say exactly where that changes over. If water is surfacing in the street or near the meter, report it to the City of Durham Department of Water Management before calling a plumber.
What the repair involves
For a single split, the damaged length is cut out and replaced. After a freeze, a careful plumber brings pressure back gradually and checks the rest of the system, since a second crack often hides behind the obvious one. A pipe that freezes every winter may need insulation, heat cable or a new route through heated space.
What affects the cost
Access is the biggest factor: an exposed pipe in a crawl space is quicker to fix than one behind tile or finished drywall. Pipe material, the number of breaks and after-hours timing also matter. Drying out the house and repairing walls are usually billed separately by other trades.
