Installation 5
Step 3. Lower the pipe into the well until the strainer is
five feet above the bottom of the well. It should
also be at least 10 feet below the well’s water level
while the pump is running
in order to prevent the
pump from sucking air. Install a sanitary well seal.
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 com-
pound on threaded pipe joints. Support the pipe so
that there are no dips or sags in the pipe, so it does-
n’t strain the pump body, and so that it slopes slight-
ly 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 suc-
tion 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.
