Replacing An Old Pump

Hazardous voltage. Disconnect power to pump before

working on pump or motor.

1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.

2. Install the pump in the system. Make sure that all pipe joints in the
suction pipe are air-tight as well as water tight. If the suction pipe can
suck air, the pump will not be able to pull water from the well.

3. Adjust the pump mounting height so that the plumbing connections do
not put a strain on the pump body. Support the pipe so that the pump
body does not take the weight of piping or fittings.

You have just completed the well plumbing for your new shallow well jet
pump. Please go to Page 6 for discharge pipe and tank connections.

Well Point (Driven Point) Installation (Figure 1)

1. Drive the well, using “drive couplings” and a “drive cap”. “Drive
fittings” are threaded all the way through and allow the pipe ends to
butt against each other so that the driving force of the maul is carried
by the pipe and not by the threads. The ordinary fittings found in
hardware stores are not threaded all the way through the fitting and can
collapse under impact. “Drive fittings” are also smoother than standard
plumbing fittings, making ground penetration easier.

2. Mount the pump as close to the well as possible.

3. Use the fewest possible fittings (especially elbows) when connecting
the pipe from the well point to the pump suction port. The suction pipe
should be at least as large as the suction port on the pump (include
a check valve if your pump is not equipped with one – see Figure

1). 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 1Teflon™ tape or
a Teflon™ based pipe joint compound. Joints must be air- and water­tight. If the suction pipe can suck air, the pump cannot pull water from
the well. If one well point does not supply enough water, consider
connecting two or three well points to one suction pipe.

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.

1. Mount the pump as close to the well as possible.

2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make
sure that the foot valve works freely.

3. Lower the pipe into the well until the strainer is five feet above the
bottom of the well. It should also be at least 10 feet below the well’s
water level while the pump is running in order to prevent the pump
from sucking air. Install a sanitary well seal.

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. 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
thepump.

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 water­tight. If the suction pipe can suck air, the pump cannot pull water from
thewell.

Pre-Charge Tank Connection (Figure 4)

1. Install two tees in the pump discharge port (see Figure 4). The pipe size
must be at least as large as the discharge port.

2. Run a pipe or reinforced hose from one arm of the first tee to the port
on the pre-charged tank.

3. Connect the other end of the discharge tee to your plumbing system.
Cap the tee with a threaded plug or a pressure gauge.

4. Check the pre-charge of air in the tank with an ordinary tire gauge. The
pre-charge should be 2 PSI less than the cut-in setting of the pump’s
pressure switch. The pre-charge is measured when there is no water
pressure in the tank. Your new pump has a 30/50 PSI switch, so adjust
the tank pre-charge pressure to 28 PSI.*

Congratulations! You have just completed the tank connection for your jet
pump. Please go to Page 7 for electrical hookup.

* Model PNCSS does not include a pressure switch.

Standard Tank Connection (Figure 5)

1. Install one tee in the pump discharge port (see Figure 5).

2. Run a pipe from the pump discharge port to the inlet port of your tank.
The pipe size must be at least as large as the discharge port.

3. Install a tee in the suction pipe near the pump. Install a reducer
bushing down to 1/8” NPT in the tee. Run tubing from the tee to the
port on the AVC mounted on the tank. Seal all joints with Teflon™
tape. See instructions provided with the tank and the AVC for details.

Congratulations! You have just completed the tank connection for your jet
pump. Please go to Page 7 for electrical hookup.

Use only

Teflon™ tape or Teflon™ based joint compounds for
making all threaded connections to the pump itself. Do not
use pipe joint compounds on plastic pumps: they can react
with the plastic in pump components. Make sure that all pipe
joints in the suction pipe are air tight as well as water tight. If

the suction pipe can suck air, the pump will not be able to pull
water from the well.

Hazardous voltage. Can shock, burn, or kill. Connect ground
wire before connecting power supply wires. Use the wire size (including
the ground wire) specified in the wiring chart. If possible, connect the pump
to a separate branch circuit with no other appliances on it.

Explosion hazard. Do not ground to a gas supply line.

Wiring Connections

Fire hazard. Incorrect voltage can cause a fire or seriously
damage the motor and voids the warranty. The supply voltage must be
within ±10% of the motor nameplate voltage.

NOTICE: Dual-voltage motors may be set for 115V or 230V. If necessary,
reset the motor to the desired voltage, as shown. Do not alter the wiring in
single voltagemotors.
