So we had to have a PVC pipe installed into the basement floor through the sump pump and then it exits through the exterior wall and then up halfway the side of the house. The pipe is about 5" thick until it gets outside then widens so that a small fan motor is installed inside. The system runs 24/7 and cost us $865 to install.
