We are new home owners and we are putting together a list of all the house maintenance we need to do. We came across checking the sump pump to ensure that it is running properly. I have looked up what a sump pum is but do not see anything of that kind in our basement unless it is in the ground. Does evey house have a sump pump and if so, what should I be looking for? We have a dry walk out basement so I am not sure if it is something that was not needed in our house.
