Operating Instructions and Parts Manual
Install foot valve or
strainer screen over
intake of suction piping.
Never use pipe smaller than 2” in
diameter for suction piping.
The suction
pipe must be kept free of air leaks. For
horizontal runs, lay pipe from the water
source so the upward slope is at least 1/4”
per foot. This eliminates trapped air. The
threaded inlet of the pump is 2” NPT.
Do not install
suction piping
near swimming areas.
DISCHARGE PIPING
Install a 1-1/2” pipe tee in the pump
discharge to allow easy priming. Plug the
end of the tee opposite the pump to allow
the branch piping to go to the spray
nozzles (See Figure 1). Remove the pipe
plug to fill the pump with water for
priming.
CONNECTION TO WATER SOURCE
The maximum vertical suction lift from
pump to the water level is 25 feet.
DRILLED WELL
1. Install a foot valve on the first section
of pipe (see Figure 2).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 10 feet
below the lowest anticipated water
level.
Leaking joints or couplings will allow air to
leak into the pipe and cause poor pump
operation or difficulty priming. Make sure
to use pipe joint compound or plumber's
seal tape on all threaded pipe
connections.
Locate foot valve
no closer than 2 feet
from the bottom of the well so sand or
sediment is NOT drawn into the system.
4. After the proper depth is reached,
install a well seal or pitless adapter to
support the pipe.
5. Slope the horizontal pipe upward
toward the pump to eliminate trapping
air.
6. When using a foot valve, a priming tee
and plug above the well seal is
recommended.
DRIVEN WELL
• Drive the point several feet below the
water table.
NOTE:
A packer-type foot valve can be
installed in the well (See Figure 3). This
type of foot valve allows the well pipe to
be filled with water when priming and
makes the inlet pipe much easier to test
for leaks. Follow the manufacturer’s
instructions when installing the packer-
type foot valve.
As an alternative, an in-line check valve can
be used with a driven well (See Figure 4).
It may be necessary to supply the pump
with multiple well points to maintain the
high flow capability of this pump. Consult
with a plumbing professional for
appropriate materials and installation
instructions.
Leaking joints or couplings will allow air to
leak into the pipe and cause poor pump
operation or difficulty priming. Make sure
to use pipe joint compound or plumber's
seal tape on all threaded pipe
connections.

Installation
• Install a foot valve on the inlet pipe
and lower into the water.
Locate foot valve
no closer than 2 feet
from the bottom of the well so sand or
sediment is NOT drawn into the system.
NOTE:
When a lake is used for the water
supply, make sure the suction pipe is deep
enough to be submerged at all times.
Slope the pipe upward toward the pump
to eliminate trapping air. The pipe must be
removed during winter months or
protected against freezing.
Protect the pipe
from damage by
swimmers and boaters. Install a screen
