Things You'll Need:
- Copper pipe cutter
- Torch kit
- 1/2 inch copper pipe
- Lead-free solder
- Stop and waste valve
- 1/2 inch copper fittings
- Steel wool
- Soldering paste
-
Step 1
Determine the location of the broken pipe you need to replace.
-
Step 2
Find the main valve where the water stems from, turn it off and then turn on the faucet that sits the lowest, to drain off excess water.
-
Step 3
Decide where you need to cut out the broken pipe. Attach the pipe cutter to the pipe, rotate the wrench around the pipe and gradually tighten the wrench with each rotation.
-
Step 4
Rub steel wool onto the end of the cut pipe to clean off any burrs.
-
Step 5
Locate the petcock screw and remove it from the valve. When reconnecting, make sure the arrow on the valve points in the direction the water will flow when turned on.
-
Step 6
Cut a new piece of copper pipe a bit longer then you need for a snug fit. Use steel wool to remove any burrs on the new pipe.
-
Step 7
Apply soldering flux on the outside of the pipe, slide the valve fitting onto the end of the pipe, heat the fitting to the pipe using a propane torch and connect the pipes.
