Had a leak in outdoor faucet that comes out of the front of the house. I tried to replace the washer on the end of the rod that goes into the house. The big drip continued so I was forced to break into the wall to access the the pipe and try to remove and replace. I am unable to get the pipe fittings to come loose after applying some serious pressure on the wrench. Not sure what to try next, maybe a torch to heat up the fittings? Anyone have an idea? Thanks!
