Sanibest – the best yet in our range

While most of our range are basically shredders, the Sanibest incorporates an actual grinder system. The Sanibest is ideal for situations where you do not control the use of it; i.e. rental unit, offices, warehouses, etc. The Sanibest is designed to deal with sanitary articles that may have been flushed down the toilet by accident. The Sanibest can be used with a round bowl or an elongated bowl. Note that in commercial installations the code requires an elongated bowl.

The Sanibest is a system that is used to install a complete bathroom up to 18 feet below the sewer line, or even up to 150 feet away from a soil stack.

• The macerating pump is connected to the spigot of a horizontal outlet toilet.
• The toilet tank is connected to the water supply.
• The macerating/pump is connected to the small diameter discharge pipe work.
• The macerating/pump is connected to the electrical supply.

The inside of the Sanibest comprises of a pressure chamber, which starts and stops the unit, and the motor, which drives the cutter and the pump.

When the flush is activated, the water flowing into the Sanibest activates a microswitch in the pressure chamber, which in turn starts the motor. The motor is sealed for life in an oil filled enclosure. A common spindle drives the impeller and the macerator blades. The moving parts therefore are kept to an absolute minimum. Water and organic waste matter, enter the chamber and are reduced to slurry as the macerator blades rotate at 3600 RPM. The reduced solids are picked up at the bottom and the impeller mounted beneath the motor ejects the waste. The pump operates at 10 PSI and pumps the effluent upward to 12 feet and/or 150 feet horizontally (with gravity fall). Once the water is discharged and the water level in the container goes down, the microswitch deactivates the unit until the flush is activated again. A normal operating cycle for Sanibest takes about 15 - 18 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal.

In addition to the toilet waste, Sanibest will also discharge gray wastewater from a variety of other sanitary fixtures, such as: a hand basin, a bath, a bidet, a urinal and even a clothes washer (Note: washing machine must drain to a laundry sink or tub first). When adding a bathtub, a base will have to be constructed, made out of 2" x 8" on edge, to allow for the installation of a P-trap and some gravity flow towards the pump unit.

The wastewater from other sanitary fixtures is discharged into Sanibest via two 1½-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 Sanibest can be turned either to the left or to the right, depending on the discharge installation.

The Sanibest automatically adjust the input rate from other sanitary fixtures, always giving priority to the discharge water of the toilet. Inlet valves operated by a simple float mechanism achieve this. For example, if the bath is being emptied and the toilet is flushed simultaneously, the inrush of water from the toilet into the container slows down or stops the discharge from other fixtures for a few seconds, until the waste from the toilet has been dealt with. As the toilet water is discharged and the level in the container goes down the float valves open and the discharge from the other fixtures resumes.

The Sanibest is designed to provide vertical pumping up to 18 feet as well as a horizontal discharge, therefore a simple non-return valve is incorporated. It has now become possible to install a complete bathroom where previously this would have been impossible or where considerable capital equipment and structural work would have been necessary.

The water closet the Sanibest is connected to, uses much less water than a regular toilet, it uses 6 liters (1.6 USG) of water per flush.
