My main sewer drain exits the house at about 5 feet above basement floor. There are four drains in the basement (floor drain, laundry sink, washing machine drain, and a pipe that sticks about one foot out of the floor) All of these lead to a pit outside the house (several feet below basement floor level) which has a pump that pumps up to to the sewer line. Do the drains in the basement need to have traps and vents?
I am trying to install a (2nd) washing machine drain onto the pipe that is one foot out of the floor. Any advice on required heights, traps, vents would be appreciated. Thank you.
