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
Suction Pipe

port on the pump. 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 or a PTFE-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
The installation shown could be used for sprinkler applications.
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 (see Figure 3). Make sure that
the foot valve works freely. Use PTFE pipe thread sealant tape or a
PTFE-based pipe joint compound on threaded pipe joints. Protect the
foot valve assembly from fish, trash, etc, by installing a screen around it
1863 0795 INT
(see Figure 3).
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.
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 or a PTFE-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 water source.
You have just completed the plumbing for your new shallow well jet pump.

Possible contamination. Do not use surface water for drinking.
