Liberty's LowPro41LP offers an easier solution for adding a basement bathroom. Unlike traditional sewage pump basins, the LowPro is designed to sit directly on the floor eliminating the costly task of breaking-up concrete. Its low profile tank can be framed around with standard 51 mm X 155 mm floor joists, totally concealing the unit for a complete finished appearance. This unit from Liberty can also save hours of installation time because it arrives fully assembled from the factory with a 2" (~51 mm) solids-handling sewage pump. Additional features include a powerful internal spray that helps break down solids and a split cover for easy access to the tank and switch without disturbing the discharge or vent pipe.
