I found small area (1 foot length) of bubbled paint over drywall seam under the master bath. Peeling the paint back showed damp drywall which has now dried indicating a leak only with use of the shower. We have stopped using the bath and no more water noted. Diverters seem to be common cause of leaks. We however have a tub spout diverter which has threading almost at the spout so this does not seem to be the problem. Our water supply is single knob for hot/cold. Have read to try filling tub with external water source to test the drain and also run only hot or cold to test these supply lines. I have closet behind the tub but would like to avoid ripping this out. Any advice in this situation?
