Richard S. wrote:"some water in the basement during heavy rains" actually listed on the disclosure for the new house means 4 inches ... The drain goes about 150 feet out to the road from the basement, it must be partially blocked somewhere.
Maybe some cute little critters nested in the drain pipe?
I had a similar drain in an old house with a VERY wet cellar. Had to put screening over the exposed end of the drain pipe, and also fluff a couple bales of hay over and around it in winter to prevent freezing.
