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.

3. Lower the jet into the well. Add pipe

as needed. Be sure to use pipe joint

compound, or plumber's seal tape

on all male threads.
