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 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- 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
suction 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 PTFE pipe thread sealant tape 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
PTFE pipe thread sealant tape. Joints must be air-
and water-tight. If the suction pipe can suck air,
the pump cannot pull water from the well.
