11. REPAIR GUIDE
PROBLEM
CAUSE
SOLUTION
The motor runs
normally, but the
water drains slowly.
The discharge pipe
is blocked. Possible
that the check valve
is half closed.
Clean the discharge
pipe Inspect the
check valve.
The water drains
slowly and the
motor works
intermittently.
Ventilation system
blocked.
Inspect the
ventilation system.
The pump doesn’t
start. The water
doesn’t evacuate.
There is no power
going to the pump.
Thermal overload
cut out.
Wait for the
thermal overload to
disengage (about
20-30 minutes).
The motor hums
and it does not
evacuate the water.
A foreign body is
blocking the impeller.
Faulty capacitor.
Contact an
authorized
technician.
The water doesn’t
evacuate and the
motor runs for a
long time.
Evacuation pipe
blocked. Partially
blocked impeller.
Contact an
authorized
technician.
After discharging
the water, the
motor restarts
several times
before stopping
completely.
Water is flowing
back into the
pump. The check
valve doesn’t close
properly.
Drain clear water to
free the check valve
or remove the valve
and clean it.
The motor runs
noisily, without
either stopping or
pumping.
Siphoning or lack
of counter pressure
in the drainage
pipe, creating an air
pocket.
Presence of a foreign
body.
Modify the
evacuation piping
in such a way as to
eliminate siphoning
or increase the
counter pressure
(for example using
smaller pipes, add
a bend in the pipe).
If the problem
continues, contact
an authorized
technician.
The motor runs, but
makes a strange
noise.
A foreign body has
fallen into the pump.
Contact an
authorized
technician.
The water backs
up into the shower
tray or bathtub.
The outflow by
gravity in the pump
is inadequate. Faulty
inlet control flap or
blockage in drain
pipe.
Make sure that the
gravity fall is at least
1/4” per foot into
the
pump from the
sanitary fixtures.
12. ADVICE
PIPE SUPPORTS
All sanitary pipe work must be sup-
ported, in accordance with the pipe
manufacturer’s recommendations.
Avoid dipping or trapping, which may
cause the build up of residual “solids”
and subsequent blockage.
BENDS
Where possible long sweeping bends
should be used. Do not use short el-
bows. If sweeping 90° elbows are not
available use two 45° elbows to make
a 90° turn.
PIPE WORK
All pipe work should be either cop-
per, PVC or CPVC (Do not use flexible
pipes). Hangers should not be less than
four feet apart to prevent pipe rattling.
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.
FREEZING
Ensure all pipe work susceptible to
freezing is adequately insulated or
heated. In unheated buildings, the toi-
let, piping and macerating unit must
be properly winterized with “RV or
plumbers” anti-freeze or drained com-
pletely.
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.
VERTICAL INSTALLATION FIRST
If vertical lift is required, this must precede the horizontal pipe run.
EASY ACCESS
The unit should be accessible and removable in the event of main-
tenance being required. During the installation a full-port ball valve
should be installed at the base of any vertical discharge pipe work
from the unit to allow easy service of the unit.
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). All horizontal piping from the macerating unit must also have
a positive gravity fall to allow free drainage when the pump stops.
NO DIAGONAL “UPHILL” PIPE RUNS
All discharge pipe work from the unit should run either directly ver-
tical upwards from it or in a horizontal plane (with a small gravity
flow) to the point of discharge.
Pipe work should not be installed with diagonal upward slope from
the unit to the point of discharge.
