Hi, I am new here so please bear with me. My question is what pipe could be leaking in my upstairs master bathroom? My shower is in a u shape, my shower head is on the open end by the sliding doors and the wall is fiberglass stuff and the flat wall is tile and the bottom foot of it caved in and is all wet, the wood and all. I noticed my shower pressure is not great and my ceiling in my downstairs living room is getting wet, just below the shower wall. I am a single female and not sure who to call or what to say or ask. Do you think this is something my homeowners insurance might cover.I also think that if you push on the fiberglass shower head wall it feels really mushy too... Thanks
