2. Thread a 2” discharge pipe into the pump 2” NPT
discharge port. Be careful to avoid stripping or cross-
ing threads.
Piping – 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 freez-
ing in piping.
Piping – Sewage Applications
(2" or Less Solids)
In any case, 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 mini-
mum flow requirements (2 feet (.6 m) per second in dis-
charge 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 Teflon™ tape on pipe connections. Do not
use ordinary pipe joint compound on plastic pipe or
pump. Pipe joint compound can attack plastics and dam-
age 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 sub-
freezing 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.
NOTICE:
For best performance of check valve when han-
dling solids, do not install it with discharge angled more
than 45° above the horizontal. Do not install check valve
in a vertical position as solids may settle in valve and
prevent opening on startup.
6. Drill a 3/16” (4.7mm) hole in discharge pipe about
1"-2” (2.5 - 5.1cm) above pump discharge connec-
tion (but below check valve) to prevent airlocking
the pump.
7. Insert the float switch piggy-back plug into a proper-
ly grounded outlet and the pump plug into the piggy-
back plug.
8. Check the installation by observing the pump opera-
tion through one complete cycle. Make sure that no
parts of the assembly interfere with the float switch.
Risk of flooding. May cause personal injury
or property damage.
Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.
ELECTRICAL
Hazardous voltage. Can shock, burn, or
cause death.
When installing, operating, or servicing this
pump, follow safety instructions listed below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow electrical cord plug to be submerged.
3. DO NOT use extension cords. They are a fire hazard
and can reduce voltage sufficiently to prevent pump-
ing and/or damage motor.
4. DO NOT handle or service pump while it is connected
to power supply.
