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 (40°C) or nuisance
tripping of the motor overload may occur.
This pump
is
indoor installation only. Failure to install indoors will
significantly increase the risk of injury or death from
electrical shock.
PIPING
Piping may be copper, steel, rigid PVC
plastic or flexible polyethylene plastic.
Flexible pipe is not
recommended on suction
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. Teflon®
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.
Plastic pipe can be used on all
installations except 2 in. deep well jet.
The 2 in. deep well jet requires 1-1/4
in. galvanized steel pipe and special
machined couplings (1-13/16 in. O. D.).
The galvanized steel pipe and the
couplings restrict the flow of return water

back to the jet unless the couplings are
machined.
PIPE SIZES
Long horizontal pipe runs and an
abundance of fittings and couplers
decrease water pressure due to friction
loss. See Chart 2 to determine the proper
pipe size.
SHALLOW WELL INSTALLATION
A shallow well jet assembly can be used
with the deep well pump when the pump
is located 25 feet vertically of the water
level. Shallow well installations have only
one pipe between the pump and water
supply (Figure 3).
DRILLED WELL (FIGURE 17)
1. Install a foot valve on the first section
designed for
of pipe (Figure 3, Illustration A).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 5 feet
below the lowest anticipated water
level.
from the bottom of the well or sand or sediment
could be drawn into the system.
4. After proper depth is reached, install a
well seal or pitless adapter to support
pipe and prevent surface. water and
other contaminants from entering well.
5. Slope the horizontal pipe upward
toward the pump to eliminate trapping
air. Sloping the pipe will also aid in
priming the pump.
DRIVEN WELL
•
Drive the point several feet below the
water table.
NOTE: A packer type foot valve can be
installed in the well (Figure 3, Illustration
B). This type of foot valve allows the
well to be filled 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.
As an alternative, an in-line check valve
