Installation
(Continued)
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 1, on page 4, 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 (See converting to
shallow well pump on page 5). Shallow
well installations have only one pipe
between the pump and water supply
(Figure 2).
DRILLED WELL (FIGURE 16)
1. Install a foot valve on the first section
of pipe (Figure 2, 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.
The foot valve
should be at least 18
in. 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 2,
Illustration B). This type of foot valve
allows the piping 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
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.
DUG WELL, CISTERN, LAKE AND SPRING
INSTALLATION (FIGURE 16, ON PAGE 8)
• Install a foot valve on inlet pipe and
lower into water.
The foot valve
SHOULD be at least
18 in. from the bottom of the well or
sand or sediment COULD be drawn into
the system.
NOTE: When a lake is used as a water
supply, make sure the inlet pipe is deep
enough to be submerged at all times.
Slope the horizontal piping upward
toward the pump to prevent trapping
air. The pipe must be removed during
winter months or protected against
freezing.
Protect the pipe from damage from
swimmers and boats.
Install a screen
around the inlet
pipe to prevent the entrapment of
swimmers.
DEEP WELL INSTALLATION
DRILLED WELL (4 IN. OR LARGER) WITH
TWO PIPE JET (FIGURES 16, ON PAGE 8
AND 3, ON PAGE 4)
1. Assemble a 1-1/4 in. foot valve (not
included) to the jet body. A 1-1/4 in.
coupling is required to connect the
larger pipe to the jet assembly.
2. Connect the 1 in. pipe threads into
the smaller opening in the jet body.
