I am not sure if it is freeon or what, but I have a rather good water leak coming from the pipe (copper) coming in from the out side unit running to the central air unit in the furnace which is in the upstairs of the house. The line runs under the floor joists in the crawl space up to the furnace. I just noticed the leak while I was in the crawl doing other work. The insulation around the pipe is really wet and dripping onto the plastic making a good size puddle of water.
My questions are: Can I remove the insulation, find the hole and patch it for now with plumbers expoxy? I really don’t think this is a matter of condensation dripping, but I could be wrong (again). The pipe was really put in badly by the installer and it is over 20 years old. (Has a lot of bends and held against the joists by metal strapping).
Also, can the pipe be replaced by myself or do I need to call in a plumber?
If it is a DIY project, what are the steps and precautions that I need to do/take?
Thanks for any input as I really can’t afford to call in a plumber due to many other problems I have had. I can replace copper plumbing lines and have the pipe and tools, but I don’t really want to solder on anything that might explode, if you know what I mean.
Thanks again
