I had to replace a bathroom faucet. The old faucet plumbing was all sweated copper. I shut off the faucet supply valve then put on a fitting for a flex hose supply line. While doing this, I had to bend the older 40 year old copper supply line a little down near the floor. One of the joints right above the floor started to leak, about a drop once every five minutes. It‘s starting to leak a little faster now. It would be nearly impossible to drain the cold water from the pipe, since this is in an apartment that shares the same meter with other units.Is there something that I can use to seal the joint on the pipe that doesn‘t require the pipes to be dry when I fix it. Maybe some sort of epoxy? I can turn off the water supply at the curb, but this turns off the water supply to all the occupied apartments.
