I live in a home on a concrete slab. Wednesday night I noticed small puddles of water on kitchen floor, thought it was a spill, by Friday I continued to see water and have my socks soaked through so I knew it wasn’t just spills or from snow. Saturday I pulled up the loose tile in the adjoining mud room and saw significant water. Dried water and realized it was streaming out of a small hole in the wall that runs behind my cabinet and dishwasher. Turned off hot and cold water under sink, put towels around the leaking wall. Cold water continues to leak drenching a full towel in an hour or two. Cold water continues to rise from tiles 3/4 of the way across my floor from dishwasher/sink. Water dial on my meter is not spinning. Towels on tiles are soaked in two hours. Cabinet foot board that runs under sink and next to dishwasher is soaked. Cabinet bottoms and under sink is dry....plumber coming out tomorrow morning but any ideas what I am looking??? Single mom without ton of money budgeted for something like this....should I be contacting my homeowners insurance?
