Please help! All I want to do is replace the old coroded fixtures in my 66 yo bathroom! I purchased a 3 handled tub/shower fauset set and proceeded to follow the instructions, but I am at a loss. I can’t the darn things (handles) off and am concerned I will damage pipes behind the wall if I use to much force. I’ve taken out every screw I can find and still am unable to budge it! How should I proceed?null
