INTRODUCTION
Please read our instructions before installing and using
your Shallow Well Water System. This will help you
obtain the full benefits of the quality and convenience
built into this equipment. It will also help you avoid any
needless service expense resulting from causes beyond
our control which are not covered by our warranty.
READ AND FOLLOW
SAFETY INSTRUCTIONS!
Carefully read and follow all safety instructions in this
manual or on pump.
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for
one of the following signal words and be alert to the
potential for personal injury!
warns about hazards that will cause serious
personal injury, death or major property
damage if ignored.
warns about hazards that will or can cause
serious personal injury, death or major property damage
if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which
are important but not related to hazards.
Never run pump dry. Running pump with-
out water may cause pump to overheat, damaging seal
and possibly causing burns to persons handling pump.
Fill pump with water before starting.
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.
Motor normally operates at high tempera-
ture and will be too hot to touch. It is protected from
heat damage during operation by an automatic internal
cutoff switch. Before handling pump or motor, stop
motor and allow to cool for 20 minutes.
1. To avoid risk of serious bodily injury and property
damage, read safety instructions carefully before
installing pump.
2. Follow local and/or national plumbing and electrical
codes when installing pump.
3. Keep well covered while installing pump to prevent
leaves and other debris from falling into well, con-
taminating well and possibly damaging pump.
4. Protect pump and piping system from freezing.
Allowing pump or water system to freeze could
severely damage pump and voids warranty.
To avoid serious injury and equipment
damage, limit system pressure to 75 pounds per
square inch (PSI) or below at all times. Over-
pressure can cause tank blowup; install relief valve
capable of passing full pump volume at 75 PSI.
5. With a new well, test well for purity before use. Con-
sult local Health Department for procedure.
Hazardous voltage. Can shock, burn,
cause death, or start fires.
6. Disconnect electrical power source before installing
or working on pump.
7. Ground pump with a ground wire run from ground-
ing lug on motor to a grounded lead in the service
panel.
8. Line voltage and frequency of electrical power supply
must agree with motor nameplate.
9. Use of fuses or wire smaller than size recommended
in owner’s manual can cause overheating, possible
fires, and will void warranty.

MAJOR COMPONENTS
AND WHAT THEY DO
Impeller and Jet
Impeller turns with motor shaft, causing water to fly out
from its rim by centrifugal force. Impeller rotation creates
a vacuum which pulls in more water. Part of the water
is diverted back to the jet where it passes through the
nozzle and venturi. This creates more vacuum to draw in
more water.
In shallow wells (less than 25 feet deep), the vacuum
created at the pump is enough to pull water to the pump.
Therefore, for shallow well use the jet is built into the
pump.
Pre-Charged Tank
The tank serves two functions. It provides a reservoir of
water under pressure and maintains a cushion of air pres-
sure to prevent pipe hammering and possible damage to
plumbing components. When water is drawn off through
the house fixtures, the pressure in the tank is lowered
and the pump starts.
Pressure Switch
The pressure switch provides for automatic operation.
Pump starts when pressure drops to 30 pounds and stops
when pressure reaches 50 pounds.
Check Valve or Foot Valve
Install a check valve as close to well as possible on well
point installations. A foot valve must be installed in the
well on dug or cased wells. See Figures 2A and 2B (Pages
4 and 5). For long horizontal pipe runs, install check valve
as close to well as possible (all types of wells).
INSTALLATION
Piping in the Well
The Shallow Well Water System can be installed on a
dug well, cased well or with a driven point. In a dug or
cased well, a foot valve and strainer should be installed
for easy priming. It should be installed five to ten feet
below the lowest level to which the water will drop
while the pump is operating (pumping water level). To
keep sediment from clogging the strainer, be sure it is
five to ten feet above the bottom of the well. Before
installing the foot valve, make sure that it works freely.
When using a foot valve, a priming tee and plug as
shown in Figure 1, are recommended.
When installed on a driven point well, your Shallow
Well Water System should have a check valve installed
as shown in Figure 2A.

Safety 5
For a pump at sea level mounted directly over the well,
be sure the total lift from the pumping water level to the
pump does not exceed 25 feet. This will be less if the
pump is offset from the well.
The maximum lift of any pump decreases at the rate of
about 1’ less lift for every 1,000 feet of elevation above
sea level. For example, at Denver, Colorado (Elev.
5,000’) the pump loses five feet of lift. The maximum
depth from which it would pump water would therefore
be 15 feet.
PUMP/TANK INSTALLATION
Pump
NOTICE: Use Teflon tape supplied with the pump or
Plasto-Joint Stik1for making all pipe-thread connections
to the pump itself. To avoid stress-cracking, do not use
pipe joint compounds on the pump.
1. Wrap male pipe threads being attached to pump with
one or two layers of PTFE pipe thread sealant tape.
Cover entire threaded portion of pipe.
2. Do not overtighten threaded fittings in the plastic
pump. Be sure you do not try to tighten joint past
thread stop in pump port!
3. If leaks occur, remove fittings, clean off old tape,
rewrap with two to three layers of tape and remake
the connection. If joint still leaks, replace the fittings
(fittings may be undersized).
4. Be sure to support all piping connected to the System.
Horizontal Piping from Well to Pump
When the pump is offset more than 25 feet from the
well, horizontal suction pipe size should be increased to
reduce friction losses. Never install a suction pipe that is
smaller than the suction tapping of the pump.
1-1/4” 1-1/2” 2”
Up to 25 Ft. 25 to 50 Ft. 50 to 200 Ft.
Discharge Pipe Sizes
When the pump is some distance from the house or
point of water use, the discharge pipe size should be
increased to reduce pressure losses caused by friction.
1” 1-1/4” 1-1/2”
Up to 25 Ft. 25 to 100 Ft. 100 to 600 Ft.
Tank
Tank is pre-charged with 40 pounds per square inch
(PSI) air pressure at the factory. Your tank requires an air
charge of 28 PSI for proper operation; check tank pres-
sure with tire gauge and adjust air charge as needed.
Tank pre-charge should be checked annually; see
instructions on Page 6.
In areas where the temperature is high for long periods
of time, the tank pre-charge pressure may increase. This
may reduce the tank drawdown (amount of water avail-
able per cycle). If this occurs, reduce the pre-charge
pressure until it is 2 PSI below the pump cut-in setting of
the pressure switch (normally 30 PSI).
It is necessary to flush all air out of the piping system and
water reservoir portion of the pre-charged tank. This is
required on new installations, pumps requiring repriming
and pumps that have been disassembled for service. Do
this as follows:
1. Open faucets furthest from tank and allow pump to
operate.
2. Air in the system will cause a sputtering flow; allow
faucets to run until you have a steady, air free stream.
3. Open and close faucets repeatedly until you are sure
all air has been removed.
4. If stream does not become steady, air may be leaking
into the system; check for leaks in the piping on the
suction side of the pump.
NOTICE: To prevent waterlogging, check tank air charge
annually.

Installation / Electrical 6
To Check Tank Air Charge
If drawdown (amount of water available per cycle)
decreases significantly, check as follows:
1. To check air charge in tank, shut off electric power to
pump, open faucet near tank, and drain completely.
2. At the air valve in top of tank, check air pressure with
standard tire gauge. Air pressure should be the same as
the turn on pressure of the pressure switch (30 PSI).
3. If the air pressure is below 30 PSI, add air to the tank.
Use an air compressor or a portable air storage tank.
4. Use soap or liquid detergent to check for air leaks
around air valve. Continuous bubbling indicates a
leak. If necessary, install new core in air valve. This is
the same as those used for automobile tubeless tires.

1. Tank nearly empty – air expands filling area above vinyl
separator.
2. Water begins to enter tank – air is compressed above
separator as it fills with water.
3. Pump-up cycle completed – air now compressed to cut off
setting of pressure switch.
4. Water being drawn from tank – compressed tank air forces
water out of separator.
5. Separator completely empty – new cycle ready to begin.

ELECTRICAL

Safety 7
Hazardous voltage. Can shock, burn, or
kill. Connect ground wire before connecting power sup-
ply 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 appli-
ances 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 warran-
ty. The supply voltage must be within ±10% of the motor
nameplate voltage.
NOTICE: 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 com-
pliance with the 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 as shown in Figure 4.
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.
4. Connect the power supply wires to the pressure
switch as shown in Figure 4.
OPERATION
Priming the Pump
NOTICE: To prevent damage to internal parts, do not
start motor until pump has been filled with water.
To prime pump:
1. Remove priming plug (Figure 1, Page 4).
2. Fill pump with water.
3. Replace priming plug, using PTFE pipe thread sealant
tape on plug threads; tighten plug.
4. Start the pump. Water should be pumped in 1-2
minutes. If not, repeat steps 1, 2 and 3.
On shallow depths to water (10 feet or less), the
pump will probably prime the first time after follow-
ing steps 1 through 4 above.
From 10 to 25 foot depths, you might have to shut off
the pump and repeat steps 1, 2 and 3 several times.
5. If, after priming pump several times, no water is
pumped, check the following:
A. Be sure suction pipe is in the water.
B. Be sure suction pipe does not leak.
C. Be sure that pump is not trying to lift water too
high (see “Piping in the Well”, Page 4).
D. As long as foot valve and check valve function
correctly and suction pipe does not develop leaks,
pump should not need repriming in normal service.

cavity. Be careful not to scratch or mark the
machined bore. It is important that this area be
clean so no old Permatex lodges behind the new
insert and causes improper seating.
B. Place a small amount of No. 2 non-hardening
Permatex on surface of insert as shown. Smooth
out with finger. See Figure 13.
C. Pull insert into cavity as shown in Figure 14.
D. Clean out any surplus Permatex from insert cavity
where new seal will be located. See Figure 15.

Cleaning Impeller
1. Follow steps 1A through 1D under “Disassembly
and Assembly of Pump” on Page 9.
2. Remove diffuser and impeller from pump per
instructions under “Removing Motor for Service
and Replacing Shaft Seal” on Page 9.
3. Clean impeller and reassemble impeller and dif-
fuser per instructions under “Removing Motor for
Service and Replacing Shaft Seal” on Page 9.
Cleaning Shallow Well Jet
To remove debris from venturi or nozzle, proceed as fol-
lows:
1. Disassemble pump per instructions on Page 9.
2. Turn venturi counterclockwise and remove it. The
nozzle is now exposed. Remove it using a 5/8” hex
socket wrench with extension. Turn counterclock-
wise. If socket wrench is not available, insert an ice
pick or similar pointed tool carefully into the nozzle.
This will dislodge debris.
3. Flush out the debris by running water through the
nozzle in the same direction as the dislodging tool
was inserted.
4. Replace nozzle and venturi. Do not overtighten!
5. Reassemble per pump instructions on Page 9.
HELPFUL HINTS
How to Handle a Gaseous Well
In some areas well water contains gases which must be
allowed to escape before the water is used. This can be
done as shown in Figure 16.
A good way of delivering gas-free water is to suspend a
pipe, closed at the bottom and open at the top, surround-
ing the suction pipe. Since the gases rise in the well cas-
ing, the water sucked down through the pipe and into
the suction pipe is free of gas. This type of well must be
vented to the outside of any enclosure.

3. Pump cycles too frequently 3. See section below on too frequent cycling
Motor runs but no *1. Pump in a new installation did 1. In new installation:
water is delivered not pick up prime through:
a. Improper priming a. Re-prime according to instructions
b. Air leaks b. Check all connections on suction line and jet
c. Leaking foot valve c. Replace foot valve
*2. Pump has lost its prime through: 2. In installation already in use:
a. Air leaks a. Check all connections on suction line, jet and shaft seal
b. Water level below suction of pump b. Lower suction line into water and re-prime. If
receding water level in a shallow well operation
exceeds suction lift, a deep well pump is needed
3. Jet or impeller is plugged 3. Clean jet or impeller according to instructions
4. Check valve or foot valve is stuck 4. Replace check valve or foot valve
in closed position
5. Pipes are frozen 5. Thaw pipes. Bury pipes below frost line. Heat pit or
pump house
6. Foot valve and/or strainer are 6. Raise foot valve and/or strainer above well bottom
buried in sand or mud
Pump does not 1. Water level in well is lower than 1. A deep well jet pump may be needed (over 25 ft.

frequently 2. Faucets or valves are open 2. Close faucets or valves
3. Foot valve leaks 3. Replace foot valve
4. Pressure switch is out of adjustment 4. Adjust or replace pressure switch
5. Air charge too low in 5. Disconnect electrical power and open faucets until all
pre-charged tank pressure is relieved. Using automobile tire pressure
gauge, check air pressure in tank at the valve stem
located at top of tank. If less than 30 pounds, pump air
into tank from outside source, until 30 pounds pressure
is reached. Check air valve for leaks, using soapy
solution, and replace core if necessary
Air spurts from 1. Pump is picking up prime 1. As soon as pump picks up prime, all air will be ejected
