I am looking at a 1950's ranch home with 2 drains and a toilet in the basement, they are at least 4 feet below the old septic line leaving the house and has a 10' ceiling. The drains work and the toilet still flushes but the 80+ year old owner wont use it. They purchased the house in the early seventies. And when the town connected the sewer they asked if they had a toilet in there basement and she said her husband told them "no".( He didn't want to loose it) Where do these drains go?
