My wife noticed a small wet spot the size of a quarter in our 1st floor ceiling. Since I replaced the tub drain 4 months ago just above this location I reinstalled it with a lot more plumber's putty. However, this did not stop the leak. I open up the ceiling at the wet spot (about 1.5" in diameter) enough for my finger to feel what appears to be a copper supply line going up to the shower/tub valve on the floor above. The line was wet. I wanted to replace the Moen 1222 Positemp valve anyway and did. Since the water was off overnight, the ceiling area that was previously wet is now dry but I do not trust that such a leak is repaired without more time. My question is, how likely is it that replacing the Moen 1222 valve, which was 20 years old, was the cause of the leak? Is there some chance that water was leaking past the valve and running back on the valve body and then down the copper supply lines until it dripped onto the ceiling? How often do you see that?
