divided into two categories:
SURFACE WATER
Water from a lake, stream, pond and/
or cistern. This water is usually not fi t for
human consumption, but may be suitable
for washing, irrigation or other household
uses.
GROUND WATER
Water found in the water bearing stratum
at various levels beneath the earth. Of
all the fresh water found on earth only 3
percent is found on the surface and 97
percent is underground.
TANKS - CONVENTIONAL STORAGE
The function of the tank is to store a
quantity of water under pressure. When
full, the tank contains approximately
2/3 water and 1/3 compressed air. The
compressed air forces the water out of
the tank when a faucet is opened. An
air volume control automatically replaces
air lost or absorbed into the water. The
usable water, or drawdown capacity, of
the tank is approximately 1/6 of the tanks
total volume when operated on a 20 lb.-40
lb. pressure setting (Figure 1).
TANKS - PRECHARGED STORAGE
A precharged storage tank has a fl exible
bladder or diaphragm that acts as a barrier
between the compressed air and water.
This barrier prevents the air from being
absorbed into the water and allows the
water to be acted on by compressed air at
initially higher than atmospheric pressures
(precharged). More usable water is
provided than with a conventional type tank.
Precharged tanks are specifi ed in terms of a
conventional tank. For example, a 20 gallon
precharged tank will have the same usable
water or drawdown capacity as a 40 gallon
conventional tank, but the tank is smaller in
size (Figure 1).
PRESSURE SWITCH
The pressure switch provides for
automatic operation. The pump starts
when pressure drops to a cut-in setting.

PACKAGE SYSTEMS
There are four jet pump/tank assemblies
sold as packages (Chart 1).
WELLS
A new well should be pumped clear of
sand before installing the pump. Sand will
damage the pumping parts and seal. The
draw-down level of the well should not
exceed the maximum rated depth for the
pump. The capacity of the pump will be
reduced and a loss of prime may occur.
Installation
LOCATION
Select a location as close to the water
supply as possible. Be sure to comply
with any state or local codes regarding the
placement of the pump. The equipment
must be protected from the elements.
A basement or heated pump house is
a good location. Make sure the pump
has proper ventilation. The temperature
surrounding the pump is not to exceed
100° F (38°C) or nuisance tripping of the
motor overload may occur.
PIPING
Piping may be copper, steel, rigid PVC
plastic or fl exible polyethylene plastic.
pipe (inlet pipe).
The pipe must be clean and free of rust or
scale. Use a pipe joint compound on the
male threads of the metal pipe. Plumber's
seal tape should be used with plastic
threads. All connections must be air tight
to insure normal operation.
Slope all inlet piping upwards towards
the pump to prevent trapping air. Unions
or hose couplings can be installed near
pump to facilitate removal for servicing or
storage. A rubber hose installed between
the water system and the house piping will
reduce the noise transmitted to the house.
PIPE SIZES
Long horizontal pipe runs and an abundance
of fi ttings and couplers decrease water
pressure due to friction loss. See Chart 2 on
page 3 to determine the proper pipe size.
SHALLOW WELL INSTALLATION
A shallow well pump can be used when the
pump is located within 25 feet vertically of

only one pipe between the pump and the
water supply (Figure 2).

NOTE: A packer type foot valve can be
installed in the well (Figure 2, Illustration
B). This type of foot valve allows the
well to be fi lled with water when priming
and makes the inlet pipe much easier to
test for leaks. Follow the manufacturer's
instructions when installing the packer
type foot valve.
Flexible pipe is NOT
recommended on suction
As an alternative, an in-line check valve
can be used with a driven well (Figure
2, Illustration C). The pipe between the
check valve and the water level will always
be under a vacuum.
Leaking joints or couplings will allow air
to leak into the pipe and cause abnormal
pump operation. Make sure to use pipe
joint compound on all male pipe threads.

NOTE: When a lake is used as a water
supply, make sure the inlet pipe is deep
enough to be submerged at all times.

the pump to prevent trapping air. The pipe
must be removed during winter months or
