Installation 5
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 fit-
tings 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)
NOTE: Surface water should not be used for drinking. The arrangement
shown could be used for a sprinkler application.
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 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 compound. Joints must
be air- and water-tight.
If the suction pipe can suck air, the pump
cannot pull water from the well.
