EASY ACCESS
The unit should be accessible and removable in the event of maintenance being required. During the installation a
full-port ball valve should be installed at the base of any vertical discharge pipe work form the unit to allow easy
service of the unit.
3-8-6
GRAVITY FALL:
The unit accepts wastewater by gravity; it does not "vacuum" in water. All inlet pipe work must have a positive gravity
fall (1/4" per foot minimum). All horizontal piping from the macerating unit must also have a positive gravity fall to
allow free drainage when the pump stops.
3-8-7
THREE FEET MINIMUM
The macerating unit must be at least 3 feet from the soil stack. This will allow the macerator to operate for an
adequate period of time to ensure efficient waste reduction.
3-8-8
SOIL STACK CONNECTION
All discharge pipe work must be connected to the soil stack by an appropriate and approved connection. A "tee" or "y"
fitting as shown is preferable.
3-8-9
NO DIAGONAL "UPHILL" PIPE RUNS
All discharge pipe work from the unit should run either directly vertical or in a horizontal plane (with a minimum ¼" per
foot) to the point of discharge. Pipe work should not be installed with a diagonal upward slope from the unit to the
point of discharge.
3-8-10
PIPE WORK
All pipe work should be copper, PVC, or CPVC. Do not use flexible piping. Hangers should not be less than 4 feet
apart to prevent pipe rattling.
3-8-11
FLUSHING
Macerating systems requires a minimum of 1.6 gallons of water to operate satisfactorily.
3-8-12
DISCHARGE
Never discharge directly into an open drain, fixture, manhole or rainwater drainpipe. It is illegal for it constitutes a
health hazard. Direct connections into sanitary waste systems only shall be acceptable.
3-8-13
FREEZING
Ensure all pipe work susceptible to freezing is adequately insulated or heated. In unheated buildings, the toilet, piping
and macerating unit must be properly winterized. Use plumbers' anti-freeze or drain completely.
3-8-14
ELECTRICITY
Before attempting any maintenance or servicing, the unit must be disconnected from the power source. The
macerating system must be connected to a Ground Fault Circuit Interrupter (GFCI).
