We wanted to replace our ten year old rubber supply hoses with new braided ones. I got the hose off the hot water supply with much vigor on my part. The cold water supply is another fish however. With slip joint pliers around the metal part that screws on the hose bibb I turned as hard as I felt prudent without breaking the pipe. Our supply lines are set into the wall with a plastic cover and I am afraid to apply heat to loosen them with my plumbing torch. I am thinking of obtaining a pencil torch to accomplish this. Any ideas from the pros and seasoned vets?
