Inspection Connection We Trying To Purchase Home, With No Sump Pump Connection, Due To Radon? How Does Flooding Stop If No Sumppump?

We trying to purchase home, with no sump pump connection, due to radon? how does flooding stop if no sumppump? - inspection connection

Dear Sir,
We strive to this house today and inspection had found that the combination of the sump pump was switched off and when we checked the sump pump was dry and rusty, which was not used to buy the full Radon has also been installed at home, my concern is how to stay out of the water in the basement, if it does not run sump pump? In Chicago, most often the flood zone, I assume that something is being installed to prevent water from the basement, said the current owner of the house she has lived for 9 years and never had problems, but no idea how the water remains in the cellar? not sure if this house is problems in the future, how much does it cost to put a new sump pump, rising just crazy ... Please indicate how the sump pump connection to connect? Thanks in advance!
