When should you install a toilet macerator

A toilet macerator is the ideal solution in all situations where it is not possible to connect directly to the main drain line. It is recommended when a toilet is to be installed in basements, attics, garages, under-floor rooms or in rooms that are far from the main bathroom.

Thanks to its ability to grind and push waste water even over long distances and uphill, this device makes it possible to overcome the limits imposed by gravity and the location of the sewer system. In addition, it is very useful in the case of renovations, when you want to create a second bathroom without intervening on the existing plumbing system.

What you need for the installation of the toilet macerator

Before starting the installation, make sure you have everything you need:

  • Toilet macerator (one inlet)
  • Toilet with wall drain (not floor drain)
  • Pipe lubricant
  • Philips screwdriver
  • Pipes, fittings, clamps (often included in the macerator package)
  • Pipe cutter or hacksaw (to adapt the length of pipes)
