I own a colonial home built in 1923 in Essex County, NJ. I have a below grade basement with a door that leads to the outside. Right when you walk out the door, there is a drain hole in the doorwell which is cement. If I look down the hole, only about an inch down I see 2 clay pipes that appear to run perpendicular to the foundation and are about a half inch apart from each other to allow water to run into the pipe.
Last year we had a series of heavy rain storms that caused water to percolate up through the drain hole and into my basement. My question is where would this system drain? Would it go into a drywell somewhere in the yard? If it discharges somewhere else in the yard, the discharge hole has since been covered by dirt/grass. I ran a hose in the hole for 10 minutes and the water did not backup. Thanks
