Electrical Code, as well as all local, state and provincial
codes. Code questions should be directed to your local
electrical inspector. Failure to follow electrical codes
and OSHA safety standards may result in personal injury or equipment damage. Failure to follow manufacturer’s installation instructions may result in electrical
shock, fire hazard, personal injury or death, damaged
equipment, provide unsatisfactory performance, and
may void manufacturer’s warranty.
Standard units are not designed for use
in hazardous liquids, or where flammable
gases exist. Well must be vented per local codes. See
specific pump catalog bulletins or pump nameplate for
all agency Listings.
Disconnect and lockout electrical power
before installing or servicing any electrical equipment. Many pumps are equipped with automatic thermal overload protection which may allow an
overheated pump to restart unexpectedly.
Never over pressurize the tank, piping
or system to a pressure higher than the
tank's maximum pressure rating. This will damage
the tank, voids the warranty and may create a serious
hazard.
Protect tanks from excessive moisture
and spray as it will cause the tank to rust
and may create a hazard. See tank warning labels and
IOM for more information.

SELECTING THE CORRECT
SELECTING THE CORRECT
JET PUMP SYSTEM
JET PUMP SYSTEM
It is important to determine which jet pump system you
need. A jet pump is a centrifugal pump with a jet (ejector) assembly. Goulds Water Technology sells three types
of jet pumps:
Shallow Well Jet Pumps with built-in jet assemblies for
maximum lift of 25'. See Fig. 1
Convertible Jet Pumps can be used for Shallow wells (to
25'), with a bolt on shallow well adapter; or deep well
(over 25') applications with a jet assembly in the well.
See Fig. 1, 2 and 3.
Deep Well Jets should only be used on deep well (over
25') applications with the appropriate jet assembly.
See Fig. 2 and 3
Use a shallow well pump or a convertible pump with a
Shallow Well Adapter for wells with a maximum suction lift of 25'. This 25' includes actual vertical lift plus
friction loss in the suction piping. Shallow well systems
are identified by one (1) pipe going to the well, lake or
river. They are good for city water booster systems and
pumping from cisterns or tanks. See Typical Installations,
Figs. 1, 5 and 6.
Deep well jet pumps are used for lifts greater than 25'
and must have two pipes going to the well. There are two
types of deep well jet assemblies, twin-pipe and packer
systems. Deep well pumps come in both vertical and
horizontal designs and in single and multi-stage models.
See Typical Installation Drawing, Fig. 2 and 3.
Consult with your Professional Dealer or Distributor to
select the best pump system for your application.
• Liquid temperature must not exceed 140° F (60°C).

PREPARING FOR INSTALLATION
PREPARING FOR INSTALLATION
Inspect the pump and the motor assembly for shipping
damage.
Insure that you have all of the parts required for a proper
installation. See component lists for different system
types. There are shallow well, convertible shallow well,
convertible deep well – twin pipe, convertible deep
well-packer, vertical deep well-twin pipe, vertical deep
well-packer, and booster systems. See Typical Installation
Drawings and Chart 1.
Check power supply voltage and select motor voltage.
Goulds ½ hp Jet pumps are factory pre-wired for 115
volts while ¾ hp and larger are pre-wired for 230 volts.
Motors from ½ hp to 1½ hp can operate on either 115
or 230 volts. The 2 hp motors operate only on 230 volts.
See Fig. 7.
Select a site where the pump and tank will not freeze.
The pump must be within 4' of the tank to prevent
switch chatter. There should be no filters or valves, other
than a wide open gate valve, between the pump and tank.
Fluid temperature must not exceed 140° F (60°C).
GENERAL INFORMATION - PIPING
GENERAL INFORMATION - PIPING
Always follow state and local plumbing codes. Goulds
Water Technology does not sell or specify pipe types or
materials, consult with your pipe supplier to determine
the best pipe for your installation. Pipes can be threaded, glued, soldered, or clamped to available fittings and
adapters. If using poly pipe with barbed connectors we
suggest you double clamp all fittings to prevent air leaks.
It is very important to eliminate high spots and dips in
suction piping as they will trap air and make the system
very hard to prime. Never route the piping up above and
then down to the pump suction. Suction piping should be
either straight from the well to the pump or should slope
upward to the pump. Pumps do not “hold” prime, piping
systems and check valves do. Go to the specific section
for your system type.
SHALLOW WELL INSTALLATION - start here
SHALLOW WELL INSTALLATION
To prevent over pumping a low yield well you can
throttle a jet pump using a ball valve in the suction line.
You should install a compound pressure/vacuum gauge
between the well and the valve. Do not throttle to more
than 22" Hg (25' lift).
In areas where freezing occurs make the transition from
vertical to horizontal below the frost line using a pitless
adapter, consult with your plumbing supplier for pitless
adapter information. In some areas they use a well seal
and a 90° elbow.
We recommend not using filters on the suction side of a
jet pump. Dirty filters increase the effective suction lift
on the pump and can starve the pump of water. This
will damage the impeller and diffuser which will affect
performance.
Install Shallow Well Adapter On Convertible Pump
Unpack the Goulds Water Technology “Shallow Well
Adapter”. Insure that the nozzle is installed in the adapter. Screw the venturi (long black tube) into the adapter.
Install the gasket and bolt the adapter to the front of the
pump using the four bolts provided. Tighten the bolts
evenly to insure proper sealing and alignment of the
venturi to the impeller. Do not over tighten the bolts. See
Chart 2.
Shallow Well Pump – jet is built-in, proceed to next step.
Attach Suction Piping To Pump
Install a barbed adapter into the 1¼" pump
suction if using poly pipe and double clamp the
fitting.
OR
Thread a pipe nipple and union into the suction port to
make a threaded pipe connection. Make sure the union is
clean and well seated. Any air leak will ruin performance
and the pump will not make pressure!
Discharge Piping
Install a tee or cross tee in the pump discharge. (They
are not supplied with the pump!) Install a pipe plug or a
pressure gauge into a reducer bushing in the top port of
the tee. This will be used as the priming port.
Suction Piping
The suction pipe should be at least as large as
the pump suction, typically 1¼". Use of smaller
pipe increases friction loss and increases effective suction lift. This will reduce flow and pressure. On offsets over 50' we recommend using
pipe larger than the pump suction. This will
reduce friction loss and improve performance.
Install a foot valve on the end of your drop pipe if the
well is 2" or larger. Lower the drop pipe with foot valve
into the well. It is best to keep it at least 5' off the bottom
of a clean well. If you set it lower you increase the chance of pulling debris into the screen or into the pump.
On sand points or driven wells you can install an in-line
check valve near the well head or at the pump and use
the well casing as the suction pipe. The closer the check
valve is to the well the easier the system will prime.

Cross Tee - the discharge line to the home attaches to
one port and the tank attaches to the other. This is called
an Off-Line Tank installation.
Tee - you can use one line to supply the house with the
tank tee installed off the line. This is called an On-Line
Tank Installation and is most common.
Note: Goulds Water Technology HydroPro Water System
tanks are shipped with a tank installation guide. Please
refer to it for more detailed tank instructions.
Do not place valves or filters between the pump and
tank, other than a fully open gate valve or “full port” ball
valve. The most common ball valves are not full port!
Most valves and filters will create excessive friction loss
and cause “switch chatter”. Switch chatter is a rapid OnOff cycling of not only the pressure switch but also the
motor. It will burn the points in the switch, the motor
points, and cause motor damage if not corrected. If for

Shallow Well Installation.
DEEP WELL TWIN PIPE – start here
DEEP WELL TWIN PIPE
Twin Pipe Suction Piping
A twin pipe jet assembly is used in wells 4" and larger.
Our 4" jet assemblies require a minimum 1¼" suction and
1" drive water pipe; 5" jets require a minimum 1½" suction and 1¼" drive water pipe. Use of smaller piping will
reduce performance in gpm and pressure. Offsets over
50' require larger pipes to reduce friction loss and
to obtain published performance.
Install Twin Pipe Jet Assembly
Check to make sure the nozzle is installed in
the jet assembly. Install the venturi tube in line
with the nozzle. On 4" jets attach the 1¼" suction and 1" pressure pipe to the jet assembly
female threads. On 5" jets the pipes should be
1½" and 1¼". Install a foot valve on the male
thread bottom port on the jet assembly or on
the end of a 34' tail pipe. The tail pipe prevents over
pumping a low yield well so the pump will not break
suction. See Tail Pipe in Technical Section.
Lower the jet assembly into the well. It should be set at
least 5' below the static water level. Keep the jet a few
feet off the well bottom to lessen the possibility of sucking debris into the jet. The connections at the well head
can be either a pitless adapter or a well seal. Priming will
be easier if you fill the pipes with water before attaching
the pump.
Connect the suction and pressure pipes to the threaded
connections on the face of the pump. This can be done
using unions and threaded pipe nipples, or barbed connectors with poly pipe. Always double clamp barbed
connectors. Make sure that the piping slopes upward to
the pump and that no point is above the pump suction.
On long offsets it is easier to prime the system if you fill
the pipes with water before connecting the pipes to the
pump. Go to Deep Well Discharge Piping.
DEEP WELL PACKER SYSTEM – start here
DEEP WELL PACKER SYSTEM
Packer Suction Piping
Packers use the area between the well casing
and the suction pipe as the drive water (pres-
sure) pipe. The 2" or 3" well casing must be
smooth and clean to insure a good seal with
the packer leathers or the system will leak and
not hold prime. The 2" packer requires 1¼"
threaded suction pipe and the 3" requires 1½".
On 2" packers only: Use the Goulds Water Technology
turned couplings part #64655 to connect the sections of
1¼" threaded pipe. This special diameter turned coupling
increases the clearance between the 2" well I.D. and the
O.D. of the coupling to allow the drive (pressure) water
to easily pass the couplings. Failure to use them will have
a negative impact on pump performance, both pressure
and gpm will decrease. The pump may easily lose prime
while pumping due to the restriction!
Using smaller than recommended pipe may reduce gpm
output. The longer the pipe the worse the affect.
Install Packer Assembly
To ease installation soak the 2" or 3" packer assembly in
warm water to make the leathers soft and pliable. DO
NOT lubricate them with grease, oil, or petroleum jelly!
The leathers must absorb water to seal the packer assembly against the well casing.
Check to make sure the nozzle is installed in the jet
assembly. Install the venturi tube in line with the nozzle.
Install a strainer (not supplied with packer assembly) on
the bottom port of the packer assembly or on the end of
a 34' tail pipe. The tail pipe prevents over pumping a low
yield well so the pump will not break suction. Attach the
packer assembly to the suction pipes using the Goulds
Water Technology’ turned couplings to connect the
sections. Insert the packer assembly into the well casing
and push it down. Attach the other pipe sections as
you lower the jet into the well. See Tail Pipe in Technical
Section.
Attach Suction Pipe To Packer Adapter
Packer systems always require a Packer Adapter at the
well head. The adapter makes the transition from vertical
to horizontal for horizontal pumps, and it connects vertical pump casings to the well casing and suction pipe. See
the list of Packer Adapters/Pump Models to see which
one your pump system requires. See Chart 1 for a list of
Packer Adapters/Pump Models.
After the jet assembly is inserted into the well, attach
the Packer Adapter to the top of the suction pipe. Screw
the top section of 1¼" male threaded suction pipe or a
threaded adapter into the 1¼" NPT female threaded hole
in the 2" packer adapter or a 1½" suction pipe into the 3"
packer adapter.
Make sure that the O.D. of the well casing is free of dirt
and burrs. With the gland bolts loosened the tapered seal
ring on the packer adapter should slide over the well
casing. After insuring that it is in place tighten the two
gland nuts to compress the seal ring and seal it to the
well casing O.D.
Install the pump by attaching it to the Packer Adapter
using the bolts and gaskets provided. Vertical models use
studs and nuts for ease of assembly.
DEEP WELL DISCHARGE PIPING
DEEP WELL DISCHARGE PIPING
All deep well jet pumps require back pressure to operate the jet assembly. To insure we
have the required back pressure or drive water
pressure we must use a pressure control valve
or some type of flow restrictor in the discharge
line. The valve must be located between the
pump and the first discharge port. It is best
to locate it as close to the pump as possible. Failure to
install and adjust a pressure control valve will result in
loss of prime during peak usage such as filling a washing
machine, bathtub or using outside hose bibs.
All ½ hp pumps can use a simple gas cock or full port ball
valve, such as our AV15.
5
All other horizontal deep well jet pumps, ¾ hp and
Hazardous pressure can
cause personal injury or
property damage.
WARNING
larger, should use an AV22KIT, or an AV22 and a JDW
tubing kit. The AV22 has a tapping to which you connect
the new, longer pressure switch tubing. This allows the
pressure switch to read the pressure on the outboard
side of the valve rather than in the pump casing. Remove
the straight or elbow compression fitting from the pump
casing. Use the pipe plug in the JDW or AV22KIT to plug
the hole in the pump casing. Remove the fitting from
the pressure switch. Cut the old tubing in half and slide
the compression fittings off the old tubing. Note that the
fitting will only slide in one direction. You can now reuse
the elbow compression fitting with the new tubing at the
pressure switch. Screw the new straight connector into
the AV22 and attach the tubing from the switch to the
AV22.
Vertical deep well pumps come with a built-in AV21 and
only need to be adjusted.
installation guide in the carton, please refer to it for more
detailed tank instructions. If you are using a tank from
another manufacturer please contact that company for
specific instructions on their tank.
Galvanized tanks are installed the same as pre-charged
tanks except they require an Air Volume Control (AVC)
to replenish air lost through absorption. The AVC requires connection to a vacuum port on the pump. The
suction side of the AVC must have a minimum 3" vacuum
for 15 seconds when the pump starts. Follow the instructions provided with the air volume control.
Priming a Shallow Well System
Priming means filling the pump and suction pipe with
water. Most shallow well jet pumps handle air well and
will evacuate air from the suction line but it may take
several minutes to prime depending on depth to water,
and pipe size and length.
After the pump is primed and flowing water at a steady
pressure you should open a few faucets and adjust the
pressure control valve to the pressure listed in the chart.
To increase pressure close the valve, AV15 or AV22, or
turn the AV21 screw clockwise. See Chart 1.

While the tank is empty check the pre-charge
air pressure with a tire pressure gauge. The
tank pre-charge should be set 2 psi lower than
the pump cut-in (turn on) pressure. On Goulds
Water Technology HydroPro Water Systems
tanks the valve cap is the primary seal so be
sure to re-install the cap after checking air
pressure. Avoid frequent air checking as you lose 1 – 2
psi every time you check. Goulds Water Technology jet
pumps are all supplied with 30 – 50 psi standard pressure
switch settings.
Locate the tank on a firm, level surface.
A pressure relief valve is recommended for all systems,
and mandatory for systems producing over 100 psi. It
should be rated less than 100 psi but greater than the
system pressure near the tank.
Make the piping connection between the pump discharge
and the tank. Complete the piping by connecting to the
house plumbing.
Note: Goulds Water Technology only sells the HydroPro
Water System tanks. They are all shipped with a tank

VENT THE PUMP FOR EASIER PRIMING!
It is easier to prime a pump if you allow all the air to
escape from the pump and the pipes, the water cannot go
in unless the air can escape!
Remove the pipe plug or pressure gauge bushing in the
discharge tee to fill the pump with water. On shallow
well pumps you should remove the 1⁄8" pipe plug located
between the suction and discharge ports to allow air to
escape as you fill the casing with water. The port will be
located on either the top of the casing or the top of the
shallow well adapter. Fill the pump and as much of the
suction pipe as possible with water through the discharge
port.
Replace the 1⁄8" pipe plug and discharge gauge/bushing.
Open the faucet closest to the pump/tank a small amount
to allow air to escape the system. Do not open it too
much or the pump will expel too much water and you
will have to reprime the pump casing. On jobs with long
suction pipes you may have to add water to the pump
casing several times to complete the priming process.
Go to Power Motor.
Priming a Deep Well System
Priming a deep well system means filling the pump and
the suction/pressure pipes with water. Deep well single
stage and multi-stage pumps require a complete prime
before starting. Filling the pipes with water before installing the pump will make priming faster and easier.
VENT THE PUMP FOR EASIER PRIMING!
To insure a complete prime we recommend removing the
angled 1⁄8" vent plug located just above the suction pipe
on horizontal pumps. This will allow the air to easily
escape as water enters. Our horizontal convertible deep
well jets should be primed through a tee or the AV22 at
the pump discharge. The tee is not supplied by Goulds
Water Technology.
Our vertical deep well jet pumps have built-in pressure
control valves. Priming is done through the pressure
gauge port on the pressure control valve. Most verticals
have a vent plug located on the side of the motor adapter
that vents the seal cavity which is the high point inside
the pump. Removing this vent plug will make priming
much easier.

pumps have a drain plug located on the side of the pump
casing near the bottom of the pump. Horizontal pumps
may have two drain plugs, one on the casing (part where
pipes attach) and another on the motor adapter. They are
also located near the bottom of the pump. Multi-stage
pumps also have 1 or 2 drain plugs and they may require
you to tip the pump or blow compressed air in one hole

WARNING: DISCONNECT POWER SOURCE BEFORE CHECKING. DO NOT MAKE ANY CHANGES WITH
POWER ON.
VOLTAGE CHANGES ARE MADE INSIDE THE MOTOR COVER,
NOT IN THE PRESSURE SWITCH.
VOLTAGE CHANGE PROCEDURE AND TERMINAL BOARD DESIGN
A.O. Smith jet pump motors have a voltage plug to facilitate simple voltage changes from 115V to 230V. All ½ HP
motors are factory wired for 115V operation. If wired for 115V, operation at 230V will destroy the windings in a
matter of seconds and will not be covered by warranty. Larger HP motors are factory wired at 230V.
Terminal Board Design:
• L1 has two (2) male terminals, one switch wire is attached to one terminal.
• L2 has two (2) male terminals, one switch wire is attached to one terminal and when set up for 115V operation the
voltage plug is connected to the other.
• “A” has 1 male terminal, the voltage plug is always connected to “A”.
Voltage Change: failure to follow these instructions may damage the windings
• 115V - Place the Black voltage plug on the open L2 male terminal and the “A” terminal.
• 230V - Place the Black voltage plug only on the “A” male terminal. The 2nd L2 male terminal will be open.

USE OF TAILPIPE ON
DEEP WELL JET PUMPS
If the capacity of a deep well jet pump exceeds the well
production, well drawdown will allow your pump to
break suction and lose prime. This can be overcome by
using a 34' tailpipe between the jet assembly and the foot
valve. Since the capacity of a pump falls off as the lift is
increased your well inflow and pump output will equalize
somewhere between the jet and foot valve. The drawing
shows the percentage of rated capacity you will get at
certain points. As in a normal situation the jet should be
set 5' below the static water level.

CHECKING SUCTION LIFT ON A
SHALLOW WELL
A vacuum gauge indicates Total Suction Lift (vertical lift
+ friction loss) in inches of mercury (Hg.). One inch (1")
on the gauge = 1.13 feet of total suction lift (based on a
pump at sea level). Practical suction lift at sea level is 25'
or 22" Hg. Deduct 1 ft. for each 1000 ft. above sea level.
Install the compound vacuum/pressure gauge in the 1⁄8"
hole in the shallow well adapter or the 1⁄8" hole between
the suction and discharge pipes on a dedicated shallow
well pump. This is the same hole that is used to connect
an air volume control.
Interpreting the gauge readings:
High Vacuum (22" or more)
• Suction pipe buried in mud
• Foot valve or check valve stuck closed
• Suction lift exceeds lift capability of pump
Low Vacuum or 0 vacuum
• Suction pipe not submerged
• Suction leak (check joints and especially unions)
Gauge needle fluctuates rapidly
• Gaseous well
• Air leak in suction line
• Well producing less than pump capacity (throttle a
ball valve in suction line do not exceed 22" Hg.) to
reduce pump capacity

A reading of 20" on a vacuum gauge placed on the suc-
tion side of the pump would tell you that you have a
vacuum or suction lift of 22.6 ft.
20" x 1.13' = 22.6 ft.
