The Saniswift drain pump is used to pump gray water away from a variety of fixtures in residential applications. The system is able to discharge the waste up to 14 feet vertical and/or 140 feet horizontal.This model is powerful and economical with a compact design and multiple inlets which makes it perfect for installations anywhere you can imagine. The inside of the Saniswift is comprised of a pressure switch and circuit board assembly, which starts and stops the unit, and the motor, which drives the pump. When the water enters the Saniswift, it activates a pressure switch which in turn starts the motor. The motor is sealed for life in an oil filled enclosure. A spindle/shaft drives the impeller and therefore the moving parts are kept to an absolute minimum. The unit pumps the effluent upward to 14 feet and/or 140 feet horizontally (with gravity fall). Once the water is discharged and the water level in the container goes down, the pressure switch deactivates the unit until water enters the unit again. A normal operating cycle for the Saniswift can be as short as 2 - 10 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal. In addition to a sink, the Saniswift will also accept and discharge the waste water from a variety of other sanitary fixtures such as: a laundry sink, a shower, a urinal. When adding a shower, a base will have to be constructed. This base should be made out of a 2" x 6" (minimum) or 2” x 8” (recommended) on edge, to allow for the installation of a P-trap and the required 1/4” per foot gravity flow towards the pump unit. The Saniswift can also accept gray water from a washing machine through an indirect connection such as a laundry sink. The waste water from other sanitary fixtures is discharged into the Saniswift via two 1-1/2 inch inlets, on either side of the housing and an additional inlet on the top of the unit. A non-return valve, which comes already assembled on the discharge rubber connector, 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. It is also highly recommended for the gray water pump to be connected to a Ground Fault Interrupter (GFI) circuit. The Saniswift is a compact unit with attractive rounded contours that fits neatly into tight spaces. The Saniswift has been certified to American and Canadian Standards.
