The Saniaccess3 is a system that is used to install a complete bathroom up to 15 ft. below the sewer line, or even up to 150 ft. away from a soil stack. It can handle the effluent from a toilet, sink, bathtub and shower. The Saniaccess3 is simplicity itself to install; there are just four connections. Inside of the unit comprises of a pressure chamber, which starts and stops the unit and the motor, which drives the stainless steel macerator blades and the pump. When the flush is activated, the water flowing into the Saniaccess3 activates a micro switch in the pressure chamber, which in turn starts the motor.
