INSTALLATION
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. Replace, if necessary.
2. Install the pump in the system. Make sure that all pipe
joints in the suction pipe are air-tight and 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.
WELL POINT (DRIVEN POINT) INSTALLATION
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 (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 PTFE pipe thread sealant
tape. Joints must be air-tight and water-tight. 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.
4. Proceed to the Discharge Pipe and Tank Connections
section.
CASED WELL INSTALLATION, 2” OR LARGER CASING
1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (Figure 2).
Make sure that the foot valve works freely.
3. Lower the pipe into the well until the strainer is 5 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.

P15001 (11-01-22)
4. Install a priming tee, priming plug, and suction pipe to the
pump (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. Include a
foot valve (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-tight and water-tight. If the suction
pipe can suck air, the pump cannot pull water from the well.
5. Proceed to the Discharge Pipe and Tank Connections
section.
INSTALLATION FOR SURFACE WATER
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.
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 (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-tight and water-tight. If the suction
pipe can suck air, the pump cannot pull water from the well.
5. Proceed to the Discharge Pipe and Tank Connections
section.

DISCHARGE PIPE AND PRESSURE TANK CONNECTIONS
PRE-CHARGE TANK CONNECTION
1. Install two tees in the pump discharge port (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 plumb-
ing system.
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.
5. Proceed to the Electrical section for hookup information.
STANDARD TANK CONNECTION
1. Install one tee in the pump discharge port (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. Remove the 1/8” NPT pipe plug from the pump Air Volume
Control (AVC) port. Run tubing from the pump’s AVC port to
the port on the AVC mounted on the tank. See instructions
provided with tank and AVC for details. AVC port location
will vary, depending on your pump model (Refer to Parts
Index).
4. Proceed to the Electrical section for hookup information.
SEALING PIPE JOINTS
Use only PTFE pipe thread sealant tape for making all threaded connections to the
pump itself. Do not use pipe joint compounds on plastic pumps as 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.

TYPICAL PRESSURE BOOSTER SYSTEM
INSTALLATION
HAZARDOUS PRESSURE. Install a relief valve as
shown capable of passing entire pump flow at 75 PSI. Pump body
may explode if internal pressure exceeds 75 PSI.
NEVER RUN PUMP AGAINST CLOSED DISCHARGE. To
do so can boil water inside pump, causing hazardous pressure
in unit, risk of explosion and possibly scalding persons handling
pump.
 The incoming flow rate must equal or exceed the minimum
pump flow requirement of 6 Gallons per Minute or the pump
will fail. As a rule, the pump will not increase the flow rate in
the system.
 A low pressure safety cutoff switch is recommended
to shut off power to the pump in case of low discharge
pressure caused by plugged nozzle, interruption to the
incoming water supply, etc.
 For pressure switch adjustment instructions, refer to the
label inside the cover of the pressure switch.
 The system can be located indoors or outdoors. Make sure
that the site is level, solid, well drained, and protected from
the weather and from freezing.
1. Turn off city water to house.
2. Install pipe as shown (Figures 6 & 7). Be sure to include
unions and stop valves so pressure booster unit can be
removed for service without interrupting household water
supply.
A spring loaded check valve ahead of the booster system
and a low pressure cutoff switch after it are recommended
You may wish to replace the standard pressure switch with
a pressure switch that includes a low pressure cutoff.
3. Use PTFE pipe thread sealant tape on all piping joints to
prevent leaks.
4. Proceed to the Electrical section for hookup information.

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.
 Dual-voltage motors are factory wired for 230 volts. If
necessary, reconnect the motor for 115 volts, as shown. Do
not alter the wiring in single voltage motors.
 Install, ground, wire, and maintain your pump in compliance
with the United States National Electrical Code (NEC) or the
Canadian Electrical Code (CEC), as applicable, and with all
local codes and ordinances that apply. Consult your local
building inspector for code information.
CONNECTION PROCEDURE
1. Connect the ground wire first (Figure 9). The ground wire
must be a solid copper wire at least as large as the power
supply wires.
2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected to the
motor, connect the green ground screw in the switch to the
green ground screw under the motor end cover. Use a solid
copper wire at least as large as the power supply wires.
3. Connect the ground wire to a grounded lead in a service
panel, to a metal underground water pipe, to a metal well
casing at least ten feet (3M) long, or to a ground electrode
provided by the power company or the hydro authority.
