Saniaccess3
The Saniaccess3 is a system that is 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.
The Saniaccess3 is simplicity itself to install; there are just
four connections.
The macerator/pump is connected to the spigot of a
horizontal rear discharge toilet.
The toilet tank is connected to the water supply.
The macerator/pump is connected to the small diameter
discharge pipe work.
The macerator/pump is connected to the electrical
supply.
The 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. The motor is sealed for life in an oil filled enclosure. A common
spindle/shaft 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 centrifugal force causes the reduced solids to be ejected through a grill into the container
where it is picked up by the impeller pump mounted beneath the motor. The unit pumps the effluent upward to 15
feet and/or 150 feet 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 Saniaccess3 takes about
10 - 15 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal.
In addition to the toilet waste, the Saniaccess3 will 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" 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 wastewater from other sanitary fixtures is discharged into the Saniaccess3 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 unit 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 top of the unit. 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 are not permitted as these are considered one-way air vent systems. It is also
highly recommended for the macerator/pump to be connected to a Ground Fault Interrupter (GFI) circuit.
Periodic maintenance can be accomplished easily without having to disconnect the unit from either the toilet or the
rest of the plumbing system. Through one service panel, a service contractor can access the electrical components
as well as the level sensor mechanism of the pump. The second service panel provides ready access to the basket
area around the macerating blades for easy removal of any large objects that may have been accidentally flushed.
The Saniaccess3 unit must be connected to our rear discharge toilet. This system uses much less water than a
regular toilet. Note: This toilet only works in combination with Saniflo systems.
The Saniaccess3 has been certified to American and Canadian Standards. Macerating standard; US: CSA Certified
& IAPMO (UPC) listed - ASME A112.3.4, CA: Macerating Standard CSA B45.9.
All items may be purchased separately. However, the Saniaccess3 works as a system and therefore a toilet bowl
(003 or 007), toilet tank (005) and the macerating unit (082) need to be purchased. An optional extension pipe
(030) is available for the pump to be installed behind the wall.
