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.

  1. The unit will connect to the back of the macerating toilet. [1]
  2. The discharge pipe can feed into a piping system and connect with the house's main drainage system to get rid of waste.

  4. Mark the mounting holes for the toilet on the floor. [3]
  5. Drill pilot holes into the basement floor.
  6. An accordion-like gasket may work as a connector. Secure the connection with a stainless steel clamp tightened with the nut driver.
  7. Open the water shut-off valve. [4]

      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.
      • An up-flush toilet may be another name for the macerating toilet. It will empty itself of waste each time it is flushed.
      • 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.
