Pi ping – Effluent Applications
(3/4” or Less Solids)
Piping must be 1-1/2” minimum to carry
volume of pump discharge. Check local codes
to determine if a check valve is required in your
system. In cold climates, check valves are not
used to prevent effluent from freezing in piping.
Piping – Sewage Applications (2” or Less Solids)
In all cases, piping must not be smaller than
pump discharge.
When installed in a sewage system, pipe must
be capable of handling semi-solids of at least
2” (5.1 cm) diameter.
The rate of flow in the discharge pipe must keep
any solids present in suspension in the fluid.
To meet minimum flow requirements (2 feet
(61 cm) per second in discharge line), size pipe
as follows:
A Pipe Size of:
Will Handle a Flow
Rate of:
1-1/2” (3.8 cm)
12 GPM (45 LPM)
2” (5.1 cm)
21 GPM (79 LPM)
2-1/2” (6.3 cm)
30 GPM (113 LPM)
3” (7.6 cm)
48 GPM (181 LPM)
NOTICE Use PTFE pipe thread sealant tape on
pipe connections. Do not use ordinary pipe joint
compound on plastic pipe or pump. Pipe joint
compound can attack plastics and damage pump.
3. To reduce motor noise and vibrations, a short
length of rubber hose can be connected
into discharge line near pump using
suitable clamps.
4. If the pump discharge line is exposed to
outside subfreezing atmosphere, then the
portion of line exposed must be installed so
any water remaining in pipe will drain to
outfall by gravity. Failure to do this can cause
water trapped in discharge to freeze which
could result in damage to pump.
5. Install a 2” check valve in the horizontal
portion of the discharge pipe. Make certain,
the flow indicating arrow, points away from
the pump. This check valve will keep the water
from either running back into the basin or into
the area being pumped out when the pump is
not running. Check valve should be a free flow
valve that will easily pass solids.

1. Attempting to lift or support pump
by power cord can damage cord and
cord connections.
2. Cord may pull apart, exposing bare
wires with possibility of fire or
electrical shock.
3. Lifting or supporting pump by power
cord will void warranty.
4. Use lifting ring or handle on top
of pump for all lifting/lowering of
pump. Disconnect power to pump
before doing any work on pump
or attempting to remove pump
from sump.
WARNING
Risk of electrical shock.
Can burn or kill.
Do not lift pump by
power cord.
