Last Spring after coming home from Vacation we found our basement flooded after an unusual week with heavy rain and snow melt. I replaced the sump pump which had stopped working not sure how old it was it came with the house (we bought the house 5 years ago) while removing the sump pump I noticed a fair amount of sand in the sump pit I set the sump pump up on a block. The pit continued to take on sand during heavy rains this summer; however has not "threatened" the pump. I also noticed in the back yard where I have 4 concrete slabs next to the house that make a small patio and one directly next to the house has "fallen" significantly and I'm wondering if this was the result of that rain/snow melt and if the slab may have broken the drain pipe. I would like to know what steps I should take to do this project myself and if my homeowners insurance should cover this. Thanks in advance
