Shower spicket in tub "leaking"
I looked at your drawing and I don't see any problem with putting the tub spout and the shower spout in any configuration you want. The control valve which turns the water onand off and mixes hot and cold is the main item to look at. There are two shutoffs behind the wall on the valve,,,,,did you turn them BOTH back ON? If your gettin cold water at both spouts and no hot from either spout then the hot water is not getting through the valve. either the hot is not turned on or a part in the mechanism is plugged up, not working, etc. Remember that as you go from hot to cold,,,,the cold gradually startsd to close up until all you get is hot. hope this helps.
