Operating Instructions and Parts Manual
INSTALLATION (CONTINUED)
SUCTION PIPING
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).
