How to Fix a Leaky Copper Pipe Cap?
Asked by xYz1234#
I'm dealing with a leaking copper water line that's hung below my joists. The cap on the pipe has failed, and the butterfly valve also seems to be broken. This line also feeds an old furnace humidifier from 1961, which I plan to replace soon. For now, since it's leaking into my workshop, I'm wondering if I can just recap it myself. If so, how should I go about it, and what kind of fitting do I need? I'm handy but not a professional plumber, so any guidance would be appreciated!

If it's a half-inch copper pipe, the easiest fix might be to cut it back a bit and use a SharkBite end cap fitting. They’re easy to install—just push to connect. Just remember to turn off the water main before you start any work!
