new guy here. I ran into a problem with my upstairs hall bath. I need the replace the cartridges for the hot and cold spickets in my tub. They are leaking from under the knobs. The problem is, I can not get the screw out of the center of the handle on the cold side. I can get it out of the hot side, but then can't get the handle off. The house was built in 74 and we've lived here for 15 years. I'm an auto mechanic by trade, so I can figure out things non related but not sure how to proceed to fix this problem. Trying at all cost to do this w/o the expense of a plumber.
Thanks for any help you can offer
