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
Figure2). 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.
You have just completed the suction piping for your new shallow well jet
pump. Please go to Page 6 for discharge pipe and tank connections.
Installation for Surface Water (Figure 3)
Possible contamination. Do not use surface water for drinking.
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
thepump.
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).
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 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
thewell.
