Pi ping – 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 minimum flow
requirements (2 feet/.6 m 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 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.
NOTICE For best performance of check valve when handling
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 connection (but
below check valve) to prevent airlocking the pump.
7. Insert the float switch piggy-back plug into a properly
grounded outlet and the pump plug into the piggy-back
plug.
8. Check the installation by observing the pump operation
through one complete cycle. Make sure that no parts of the
assembly interfere with the floatswitch.
Risk of flooding. Can cause personal injury and/or
property damage. Failure to make this operational check may
lead to improper operation, premature failure, and flooding.
Electrical
Risk of electric shock. Can shock, burn or kill.
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 pumping and/or
damage motor.
4. DO NOT handle or service pump while it is connected to
power supply.
5. DO NOT remove grounding prong from plug or modify
plug. To protect against electrical shock, the power cord is
a three-wire conductor and includes a 3-prong grounded
plug. Plug pump into a 3-wire, grounded, grounding-type
receptacle. Connect pump according to electrical codes
that apply.
