Replacing An Old Pump
Risk of electric shock. Can shock, burn or
kill. 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 Discharge
Pipe and Tank Connections.
Well Point (Driven Point) Installation
1. AsshowninFigure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 well
driving force 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).

Pressure Booster System Installation
Risk of explosion. 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.
Risk of explosion and scalding.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.
NOTICE 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
values shown in Table II or 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and7).Besure
to include unions and stop valves so that 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).

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8.
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 (3m) 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8.
Operation
Risk of explosion and scalding.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.
Risk of burns.Neverrunpumpdry.Running
pump without water may cause pump to overheat,
damaging seal and possibly causing burns to persons
handlingpump.Fillpumpwithwaterbeforestarting.
1. Remove the priming plug from the priming tee and
fillthepump(Figure10).Fillallpipingbetweenthe
pump and the well and make sure that all piping in
the well is full. If you have also installed a priming
tee in the suction piping, remove the plug from the
tee and fill the suction piping.
2. Replace all fill plugs.
3. Poweron!Startthepump.Ifyoudon’thavewater
after 2 or 3 minutes, stop the pump and remove the
fill plugs. Refill the pump and piping. You may have
to repeat this several times in order to get all the
trapped air out of the piping. A pump lifting water
25’maytakeaslongas15minutestoprime.
4. After the pump has built up pressure in the system
and shut off, check the pressure switch operation by
opening a faucet or two and running enough water
out to bleed off pressure until the pump starts. The
pump should start when pressure drops to 30 PSI and
stop when pressure reaches 50 PSI. Run the pump
through one or two complete cycles to verify correct
operation. This will also help clean the system of dirt
and scale dislodged during installation.
