Can someone give me a heads-up and/or link to more info on a DIY repair.
I've got a combo tub/shower with a common three-handle arrangement, the center handle switches from tub faucet to shower. Unfortunately there's no brand name in sight. I've replaced the rubber washers in the hot and cold valves numerous times. Lately, the tub faucet dribbles a fair bit in the shower position. I think it's getting gradually worse and I'd like to fix it.
My shower is tiled, and there's no easy access to the back side of the plumbing; the other side of the wall is in a closet, covered with drywall. I'm hoping to get some knowledge before attacking this. Is this a reasonable DIY repair? Simple like a washer, or hard like replacing the entire valve assembly? Will I find repair parts in the big box or hardware store? Can it be done from the front? If not, maybe by breaking though the drywall on the other side of the wall? Is this going to lead to a bathroom remodel?
TIA, Joel
