What is the minimum discharge size for a macerating toilet?

The minimum discharge size for a macerating toilet is typically 3/4 inch. This size is crucial because it allows the waste and water to be efficiently pumped from the macerator to the main sewer line. Macerating toilets operate by grinding waste into a slurry that can be more easily transported through smaller pipes than standard gravity toilets. If the discharge size were any smaller, it could lead to clogs and reduced performance, preventing the proper evacuation of waste and potentially causing backups. A discharge size larger than 3/4 inch, for instance, may be unnecessary and could complicate installation without adding significant benefits. Therefore, 3/4 inch is the recognized standard for effective functionality in macerating toilets.
