Whether you are a seasoned DIY enthusiast or a first-time plumber, this guide will help you successfully install a macerating toilet in your space.

How To Install A Macerating Toilet

Step 1: Prepare the Area for Installation

Before you begin installing your macerating toilet, you need to prepare the area where it will be installed. Start by turning off the water supply to the area where you will be installing the toilet. Next, remove any existing fixtures or plumbing in the area. If you are installing the toilet in a new location, you will need to install the necessary plumbing and drainage pipes.

Step 2: Assemble the Macerating Unit

The macerating unit is the device that grinds waste into a slurry and pumps it to the main plumbing system. To assemble the macerating unit, start by attaching the discharge elbow to the unit.
