Hi, I was putting up a picture on the wall, and drilled a pinhole into the insulated copper pipe running from the outside unit to the attic.
I got someone in to repair it and he told me it would be $. I think he is retarded. He wanted to cut the entire pipe and weld (not solder, weld) in an entire new section.
The hole in the pipe is probably about 1/4 mm. Less than a pinhole. I could stop the gas coming out with my thumb.
I am thinking I can get a coupler, cut in in half, smear it with epoxy, put it over the hole and put 4 hoseclamps on it. right now I have a piece of duct tape over it and it holds the gas in (remember - small hole).
Anyone have a better suggestion? What is the proper way to repair a hole in the pipe without soldering
The Repair DIY style
Well here is what I did about my pinhole in my air conditioner pipe.I first drained most of the freon from the system, but not all. I wanted to make sure the system was still under pressure, so that I could make sure in one month if it was still under pressure (ie - it didnt leak).Then the trick was to figure out how to repair a hole while the system was under pressure.So I did this. First I made a small amount of epoxy, and put it on the hole, which of coarse it bubbled around. Then in a flash, I put some duct tape over that, then used a C clamp to hold the duct tape down over the hole and stop if from leaking.In about 15 minutes, I removed the C clamp and took off the duct tape. The epoxy had set, and the hole had a temporary seal.I could then work on stage 2, where I made a complete patch, without worrying about the pipe spurting out.I cut a copper sleeve / joiner in half, so that I had a cup to cover the entire area. I smeared more epoxy over the cup, and the pipe, then put it on with 4 hose clamps, and tightend it up. It's about 1/2 inch of epoxy from the edge of the copper cup to the hole, so if it leaks, it will have to get through 1/2 inch of epoxy.As I write this, the second epoxy patch has now set, and I think it will be fine. The hose clamps are epoxyed in with the entire thing, so there's no turning back now.I think the trick was getting the first temporary repair on, before doing the second complete epoxy set. This prevented any bubbling, yet still allows me to test the pressure before calling someone to fill it up.Anyway,
