installing a bathroom sink?

[mjf]

I'm having trouble connecting the drain to the top of sink, the elbow is off by a 1/2 inch it would line up, plus I can't get the drain hooked up. I need help! Thank you

Either use a tubular off-set to make it up or, if there isn't room for it, you may have to repipe with a new trap. If it's a brass trap soldered into copper pipe, cut it off and make it up with a fernco designed for whatever size tubular pipe you're working with. If it's a solid trap made up onto an iron nipple in the wall, you've got a tough job on your hands. If that's what it is, carefully heat the connection to the nipple with a torch, tap gently with a ball peen hammer then try to work it off with a pipe wrench. Be careful not to egg the pipe. There is also the possibilty that the nipple may snap off in the wall. If that happens, you will have to open the wall in order to repipe it. If you are successful in getting the trap off the nipple then use whatever size adapter is nessicary on the nipple to pipe the new trap

Good luck!
