Toilet and Pump Installation
Part 1: Attaching Connections
Vent Line Shower/Tub/Sink Discharge
The macerating unit must
be vented. It has 2 inlets
on the top of the cover: a
1 ½” cap and a hole of
smaller diameter.
The unit must be
connected to a vent
system according to the
plumbing codes.
Put the waste inlet
(provided) on the cap and
clamp it down.
After, connect the vent
pipe. All fixtures
connected to the system
must also be vented.
To connect to the side entries
of the case, use the side
connector.
Secure with clamps.
Plug the unused inlet with
blanking plug after greasing
the joint.
Ensure when con
necting a
shower to the macerating unit
that the underside of the
shower tray is raised at least 9
inches from the floor.
These macerating units have an elbow and a bushing.
Simply cut off the appropriate portion of the bushing in
order to fit it to the discharge pipe.
Use ridged wall pipe, not flexible pipe or hose, as
flexible pipe may distort over time. Use ¾” or 1”
discharge pipe.
Install a “full-part” ball or gate valve and a union in the
discharge pipe in order to facilitate the removal of the
macerating unit. Place the union or hose connector
followed by the valve of the lower portion of the
discharge pipe. If you need the unit to pump both
vertically and horizontally, remember that 3 feet of
vertical lift is equal to 30 feet of horizontal run.
Discharge pipe work can be made from ¾” diameter
Type M Copper, CPVC, or PVC. Use long turn bends,
not elbows. The connection to the soil-stack or sewer
pipe must be made with an approved wye fitting. If you
are not comfortable with this procedure, have a
plumbing contractor install for you.
