Yahoo Autos How to Repair Pinhole Leaks in Copper Pipe Without Soldering
Water leaks are a homeowner's nightmare, but there's a good chance you can repair it yourself without calling in an expensive plumber.
Pinhole leaks are commonplace and the only way to properly fix them is by removing the leaking section of pipe and replacing it, with either copper, PEX, or PVC pipe. Copper and PEX piping are the preferred alternatives and can be used in place of the leaking pipe by using sharkbite couplings.
Start by turning off the main water line to your home and bleeding the system of water so you don't get drenched when opening up the pipe. Then use a pipe cutter to remove the leaking section. The round AutoCut pipe cutters work great as they can be used in tight spaces and cut the pipe as you turn it clockwise.
