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 – double (twin) pipe, convertible
deep well-single pipe (packer), and booster systems. See
Typical Installation Drawings and Chart 1.
Check power supply voltage and select motor voltage.
Red Jacket Water Products
pre-wired for 115 volts while
wired for 230 volts. Motors operate on either 115 or
230 volts. See Fig. 6.
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, provincial, and local plumbing
codes. Red Jacket Water Products 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.

Suction Piping Guidelines
The suction pipe should be at least as large as

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.

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.
Convertible Shallow Well Pump
Install Shallow Well Adapter On Convertible Pump
Unpack the Red Jacket Water Products "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.

Attach Suction Piping To Pump
WARNING
Install a barbed adapter into the 1
suction if using poly pipe and double clamp the
fitting.
Hazardous pressure can

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.
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.

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 On-
