Lawn Sprinkler Pump
Installation (Continued)
For horizontal runs, lay pipe from the
water source so the upward slope is at
least 1/2" per foot. This eliminates
trapped air. The threaded inlet of the
pump is 2" NPT.
Do not install suc-
tion 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 sec-
tion 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. Make sure to use
pipe joint compound or Teflon
all pipe connections.

5. Slope the horizontal pipe upward
toward the pump to eliminate trap-
ping air.

6. When using a foot valve, a priming
tee and plug above the well seal is
recommended.
DRIVEN WELL
1. 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 manufac-
turer'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
no closer than 2
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. Make sure to use
pipe joint compound or Teflon
all pipe connections.
