Suction Pipe
From Well
INSTALLATION FOR SURFACE WATER (FIGURE 3)
Step 1. The pump should be installed as close to the water as possible,
Step 2. Assemble a foot valve and suction pipe (see Figure 3). Make sure
Step 3. Lower the pipe into the water until the strainer is five feet above the
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.

connections.

assembly from fish, trash, etc, by installing a screen around it (see
