Macerating Toilet Systems

by Liberty Pumps

Save time and money! This is the perfect system for a remodel or new addition where gravity drain lines do not exist. This new Macerating Toilet System features an attractive, ADA comfort toilet with a macerating pump that pumps the waste to any existing gravity sewer line in the building, without having to break up the concrete floor. Install it anywhere you want it - even in the basement! Additional inlets for a sink and tub/shower makes this even better than a toilet system - it's truly an entire bathroom system!

Frequently Asked Questions

Q. "How hard is this system to install?"
A. The system is designed for easy installation. All you need is a 115v electrical service, a 1/2" water supply line, and a structurally sound, relatively level surface to set the toilet and tank on. The discharge pipe connection allows the unit to be plumbed in virtually any direction, and once the system is tied into the sewer pipe, simply plug in to A/C power and go.

Q. "What does ADA mean?"
A. ADA stands for Americans with Disabilities Act. The toilet that is included with the complete system meets the Americans with Disabilities Act and it's requirements for accessible and useable facilities. This toilet was designed with comfort in mind. It is 16.25" tall without the seat, making it very easy and comfortable to use.

Q. "How does the system work?"
A. Waste water enters the tank from either the rear flush toilet or the side inlets. As the liquid fills the tank, the factory pre-set mechanical float switch energizes the macerator, which in turn cuts and evacuates the waste water. The positive on-off action of the mechanical float switch prevents the system from "dry-cycling", or running without sufficient liquid present.

Q. "How noisy is a macerating toilet system?"
A.There are several factors which will change the noise level of a macerating toilet system, including the size of the room, furnishings, connections, etc, so it's nearly impossible to predict exactly how loud a system will be once installed. For that reason, most manufacturers won't provide a decibel rating, but state that a macerating toilet system will definitely be audible if you're in the same room when it's running. Typically, the noise level of a macerating toilet system is louder than the humming of a refrigerator but quieter than most dishwashers. The noise shouldn't travel throughout the house.

Q. "Will this toilet meet my town's high efficiency toilet laws?"
A. While we do make an effort to be aware of upcoming plumbing-related legislation, we simply cannot keep up with all the plumbing-related legislation for all municipalities. As part of the selection process for new fixtures, we highly recommend contacting your local code enforcement agencies for the latest plumbing fixture requirements. This will help you select the correct fixtures for your home or business, and will also help avoid nasty surprises should your project require a permit or inspection. If working with a plumber, confirm he or she is well aware of current legislation in your area, too.
