Plumbers repair a burst copper pipe by shutting off and draining the line, cutting out the split section, and installing a new piece of pipe with proper fittings. The repair is then tested under pressure before walls or ceilings are closed.
Step 1: Shut Off and Drain
The water is turned off at the main valve or a nearby valve. Faucets are opened to drain the line. Copper needs to be dry and empty for most repair methods to work well, so this step can take a few minutes.
Step 2: Remove the Damaged Section
The plumber looks at the pipe on both sides of the break. A pipe that froze may be bulged or thin beyond the visible crack. Cutting back to solid, round pipe gives the new connection a good base. A tubing cutter makes clean cuts without crushing the pipe.
Step 3: Join the New Piece
- Soldered fittings: the traditional method using heat and solder to seal couplings.
- Press fittings: a tool presses fittings with built-in seals onto the pipe, with no open flame.
- Push-fit fittings: fittings that grip the pipe when pushed on, often used where heat is unsafe.
The choice depends on the location, nearby materials, access, and local code. Work near wood framing or insulation needs extra care if heat is used.
Step 4: Test and Check
The water is turned back on slowly while the plumber watches for leaks. Nearby joints are checked too, since a freeze can weaken more than one spot. Once the repair holds, the area can be dried and patched.
If the pipe froze, the plumber may also suggest insulation or rerouting so it does not happen again.
For a split copper line, a proper cut-out repair lasts far longer than tape or clamps. If you have older copper with several weak spots, you can discuss a longer-term fix with our team at (833) 603-1840.
