: : I have a section of bad pipe in a ceiling,can I use brass compression couplings to make the connections when I replace the copper pipe.
: Jim: I have used brass compression fittings on water services in industrial plants where the upstream shut-off valve wouldn't hold, and the trickle of water was enough to prevent soldering. This was a spot where the next upstream shut-off valve would shut down some process equipment. We used a tube by male pipe thread adapter, with a valve screwed on the adapter. Cut the pipe, slip the compression fitting on, tighten the nut, and close the valve. We could then solder downstream. You should check that your local codes don't forbid using these fittings. Compression fittings are a LOT more expensive than sweat-on copper couplings, though. Remember that 1/2" copper pipe equals 5/8" tubing, and that 3/4" pipe equals 7/8" tubing. Tony
