DIY Sewage Ejector Pump Plumbing

Homeowners install sewage ejector pumps onto toilet discharge pipes when gravity cannot force the waste down the regular sewage pipe. Ejector pumps rely on three different pipes to operate: an inlet pipe leading into the basin that fills with wastes, an outlet pipe that pumps the wastes into the regular sewer pipe and a vent pipe that runs to the roof to vent the fumes that can build up in the basin.

Instructions

- 1
  Cut a hole in the roof of your home with a jigsaw. Place vent flashing around the hole, securing in place with a hammer and roofing nails. Run a 2-inch pipe through the hole and flashing down to the basin cover to properly vent the sewage pump basin fumes.
- 2
  Apply silicon caulk around the pipe from the underside of the roof. Slip the vent pipe into the basin so that only 2 inches go through the lid.
- 3
  Cut the sewage pipe line where you will pump the waste from the toilet. Rub sandpaper along the edges of the pipe to remove plastic burrs.
- 4
  Apply plumber's glue to the inside of the tee pipe. Slide the tee pipe into place, holding it for several seconds for the glue to set.
- 5
  Run pipe toward the basin. Glue in place a stop valve. Attach an elbow pipe and run pipe toward the sewage ejector pump in the basin. Place a coupling on to the pipe with a check valve about 8 inches above the basin lid.
- 6
  Continue running a pipe down through the basin lid and into the ejector pump. Run a third pipe through the inlet hole on the side of the basin to the toilet's discharge pipe. Glue the pipe into place.
