To have a toilet in a basement, a macerating toilet can be used. This kind of toilet connects to a macerator unit behind it, which pumps waste through a 3/4-inch (1.9 cm) discharge pipe after grinding it up with stainless steel blades. The macerating unit should be installed in the basement first since the unit goes behind the toilet and connects to piping that sends waste up to and through a house's main plumbing system. Try following these steps to install a basement toilet.

Place the macerator unit so it will be behind the toilet's location. The unit will connect to the back of the macerating toilet.[1]
Connect a discharge pipe to the macerator's drainpipe. The discharge pipe can feed into a piping system and connect with the house's main drainage system to get rid of waste.- Fit the macerator unit manufacturer's discharge adapter onto the discharge pipe and the macerator's outlet port to connect them. The port is on top of the macerator unit.
- Tighten the discharge adapter with the nut driver so it is secure.
- A gate valve is recommended on the discharge line near the macerator's outlet. This will come in handy if the macerator needs to be serviced. Without the macerator in place there won't be anything to hold the waste in the vertical run of the discharge line.

Connect the macerator unit to an existing vent stack inside the house with PVC vent piping. This provides necessary ventilation.[2]- You may need to apply PVC pipe primer and cement before fitting the PVC piping to the vent stack and macerator unit.
- A new vent line may be ran if an existing vent stack is inaccessible.

Place the toilet in its desired position in the basement. Mark the mounting holes for the toilet on the floor.[3]
Move the toilet away. Drill pilot holes into the basement floor.
Use 2 brass screws to secure the toilet in place over the holes.
Connect the macerator unit to the back of the toilet. An accordion-like gasket may work as a connector. Secure the connection with a stainless steel clamp tightened with the nut driver.
Connect the basement toilet with the water-supply line. Open the water shut-off valve.[4]
Plug the unit into a GFCI outlet. (Ground Fault Circuit Interrupter)
Flush the toilet. Check for any leaks.

Tips
- The macerator unit can also connect a sink (lavatory) or shower for basement plumbing as well. PVC pipe and fittings are needed for the connections.Thanks
- An up-flush toilet may be another name for the macerating toilet. It will empty itself of waste each time it is flushed.Thanks
- Other waste storage systems such as creating a sewage basin or using a floor-mounted polyethylene tank can possibly be used in basements. These options use a standard toilet, which works differently from a macerating toilet.Thanks
