Client called us out today due to their basement plumbing sewage ejector pump that was recently replaced by a friend of clients, constantly humming and not working. We removed the basin lid, and discovered the pump that was installed by the friend was not the proper type of pump. The existing pump was a SUMP pump, which is only meant for water which is why it was not working. We removed old pump and installed new Zoeller .4 HP sewage ejector pump with new 2” pvc ball valve and new check valve as well. Set pump in place and then secured lid. Connected all the pipes with glue and primer then let it set up for 15 minutes. Tested, no issues. Pump now working as it should. 3 yr manufacturer warranty 1 yr parts and labor from us
