What's actually causing this
Pipes leak at joints when thread sealant dries out, at elbows where water pressure concentrates, or anywhere corrosion has weakened the pipe wall. PVC joints also crack from freezing temperatures or physical impact.

Step-by-step fix
-
1
Shut off the water supply
Turn off the main water shutoff valve. Open a faucet downstream to drain remaining pressure from the pipe.
-
2
Dry the pipe completely
Use a towel and fan to dry the area around the leak. No repair compound bonds to a wet surface.
-
3
Apply a pipe repair clamp (temporary)
Center the rubber gasket over the leak and tighten the clamp screws evenly. This buys time for a permanent repair.
-
4
Cut out and replace the damaged section (permanent)
Cut 2 inches on either side of the damaged area using a pipe cutter. Install push-to-connect (SharkBite) couplings on each side for a no-solder permanent fix.
-
5
Test under pressure
Slowly turn the water back on. Watch the repair area for 10 minutes. Check all connections for moisture.

- The leak is inside a wall or ceiling — accessing it requires opening drywall.
- The pipe is corroded or crumbling — a section repair won't solve systemic corrosion.
- You can hear running water but can't locate the source.
- The pipe is part of a gas line — never attempt gas line repairs yourself.
