INSTALLATION
4.
Install a priming tee, priming plug, and suction pipe to the
pump (Figure 2). Connect the pipe from the well to the pump
suction port, using the fewest possible fittings, especially
elbows, as fittings increase friction in the pipe. Include a
foot valve (Figure 2). The suction pipe should be at least
as large as the suction port on the pump. Use PTFE pipe
thread sealant tape on threaded
pipe joints.
Support the pipe so that there are no dips or sags in the
pipe, so it doesn't strain the pump body, and so that it
slopes slightly upward from the well to the pump (high spots
can cause air pockets which can air lock the pump).
Seal the suction pipe joints with PTFE pipe thread sealant
tape. Joints must be air-tight and water-tight. If the suction
pipe can suck air, the pump cannot pull water from the well.

Proceed to the Discharge Pipe and Tank Connections
section.

INSTALLATION FOR SURFACE WATER
1.
The pump should be installed as close to the water as
possible, with the fewest possible fittings (especially
elbows) in the suction pipe. The suction pipe should be at
least as large as the suction port on the pump.
2.
Assemble a foot valve and suction pipe (Figure 3). Make
sure that the foot valve works freely. Use PTFE pipe thread
sealant tape on threaded pipe joints. Protect the foot valve
assembly from fish, trash, etc, by installing a screen around
it.
3.
Lower the pipe into the water until the strainer is five feet
above the bottom. It should also be at least 10 feet below
the water level in order to prevent the pump from sucking
air.
