Installation
Step 4. Install a priming tee, priming plug, and suction
pipe to the pump (see 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 (however,
include a foot valve – see Figure 2). The suction
pipe should be at least as large as the suction
port on the pump. Use teflon tape or a teflon-
based pipe joint compound 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 teflon tape or a teflon
based pipe joint compound. Joints must be air-
and water-tight. If the suction pipe can suck air,
the pump cannot pull water from the well.

INSTALLATION FOR
SURFACE WATER (FIGURE 3)
Step 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 suc-
tion pipe should be at least as large as the suction
port on the pump.
Step 2. Assemble a foot valve and suction pipe (see
Figure 3). Make sure that the foot valve works
freely. Use teflon tape or a teflon-based pipe joint
compound on threaded pipe joints. Protect the
foot valve assembly from fish, trash, etc, by
installing a screen around it (see Figure 3).
Step 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.
Step 4. Install a priming tee, priming plug, and suction
pipe to the pump (see Figure 3). 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
teflon tape or a teflon based pipe joint com-
pound. Joints must be air- and water-tight. If the
suction pipe can suck air, the pump cannot pull
water from the well.
