Installation For Surface Water - Pentair STA-RITE SN Serie Manual Del Propietário

Installation
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.
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)
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 (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).
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. Joints must be air- and water-tight. If the suction
pipe can suck air, the pump cannot pull water from
the well.
