Last night I inspected a Townhouse and while testing the sump pump I noticed that it was backing up into the laundry tub. The laundry tub is in between the sump pump and the line outside. Past the Laundry tub the piping sags due to lack of hangers. I feel that water is laying in the low part of the pipe and the sump pump has a hard time pushing the water.
Is there supposed to be anything connected between the sump pump and the disharge to the storm sewer?
