Our technicians removed the existing sump pump pit and installed new DES closed lid sump pump pit. They backfilled around the entire pit with 3/4 blue stone and installed new Zoeller M-53 sump pump alert system with a new check valve as well. They tested the discharge and noticed the 4 inch pvc line tied to the discharge was backed up. They spoke with the contact person and she will get the maintenance done on the lieder piping cleared.
