Cut Out Damaged Pipe

Cut Out Damaged Pipe

Snap a rotary pipe cutter onto the pipe to one side of the damaged area. Rotate it in the direction indicated on the cutter side (it only cuts one way) to cut through the pipe. If you don’t have a rotary pipe cutter, a hacksaw can be used. Repeat this step on the other side of the damaged area to remove and discard the damaged section of pipe.

Step 3

Connect Replacement Pipe

Connect Replacement Pipe

Measure the length of damaged pipe and using a rotary pipe cutter or hacksaw, cut a new piece of copper pipe with the same dimensions. The pipe connectors used are called Instantor fittings. Use the Instantors to connect the ends of the existing and new pipe together.
