Is there waterproof puddy for copper piping? I have a pinhole leak in my wall behind the water heater with the insulation I don't want to start a fire with sodering so is there waterproof puddy that I can seal a clamp with?

JB Weld or FastSteel will do the job. If you would like a link to pipe repair kits click on back. Regards, Tom

Where can I purchase jbweld or faststeel?

That depeend on where you are located. In Canada, Canadian tire carries these products. In the USA I would recommend trying larger chain hardware and automotive chains.
