mud brick was the wrong choice of words i guess. Good old mortar bed and membrane shower! House is a modular so ground moisture isn't a problem being up off the ground..airhandler moisture is another story!
I made this quick video to show the damage a leaking air handler drip pan did to our bathroom floor. It's located in the hallway right behind the bathroom behind a door that never get's opened. There's no telling how long it was leaking but I'm sure it was a good while. We first started noticing...
