Size:1 Discharge Flow at 0 ft. (gallons/hour)- 27 From the Manufacturer The SANIPLUS is a system used to install a complete bathroom up to 15-Feet below the sewer line, or even up to 150-Feet away from a soil stack. It can handle the effluent from a toilet, sink, bathtub and shower. It offers a high level of styling that makes it the ideal centerpiece for a modern bathroom. The inside of the SANIPLUS is comprised of a pressure chamber, which starts and stops the unit, and the motor, which drives the stainless steel macerator blades and the pump. The unit pumps the effluent upward 15-Feet and/or 150 horizontally (with gravity fall). Once the water level in the container goes down, the micro switch deactivates the unit until the flush is activated again. A normal operating cycle for SANIPLUS takes about 7-9 seconds. In addition to the toilet waste, the SANIPLUS with also discharge gray water from a variety of other sanitary fixtures such as: a sink, a bathtub, a shower and a urinal. When adding a bathtub or shower, a base will have to be constructed. This base should be made out of a 2-Inch X 6-Inch(minimum) or 2-Inch X 8-Inch(recommended) on edge, to allow for the installation of a P-trap and the required 1/4-Inch per foot gravity flow towards the pump unit. The wastewater from other sanitary fixtures is discharged into the SANIPLUS via two 2-Inch inlets on either side of the housing. Either one or both inlets can be used as required. The discharge elbow on top of the SANIPLUS can be turned either to the left, to the right, or towards the back, depending on the discharge installation. A non-return valve, which comes already assembled on the discharge elbow, prevents back flow into the unit. This unit has been designed with a vent connection on the lid. All plumbing codes require connection to a vent system. Please note that the vent system should be a two-way air vent. The use of mechanical vents, air admittance valves, or similar devices is not permitted as these are considered one-way air vent systems.
