Installation Instructions

Jet Assembly for
Well Pumps
1. Assemble a 1-1/4 in. foot valve (not
included) to the jet body. A 1-1/4 in.
threaded pipe nipple is required to
connect the foot valve to the jet assembly.
2. Connect the 1 in. pipe; thread it into the
smaller opening in the jet body.
3. Lower the jet assembly into the well,
adding 1-1/4 in. suction pipe and 1 in.
drive pipe as needed. Be sure to use
pipe joint compound on all male threads.
4. Position the jet assembly 10 - 20 ft.
below the lowest anticipated water
level. The jet assembly should never
be closer than 5 ft. from the bottom of
the well or sand and sediment may be
drawn into the system.
5. Install a well seal to support the pipe
and prevent surface water and other
contaminants from entering the well.
6. Install the horizontal pipes from the well
to the pump. Piping from the vertical
well pipes to the pump should never be
smaller than the well pipes.
7. Slope both pipes upward toward the
pump to prevent trapping air. If the
horizontal distance exceeds 25 ft.,
see pump instruction manual for the
recommended pipe sizes.
NOTE: SINGLE PIPE PACKER JETS RELY
ON THE SPACE BETWEEN SINGLE PIPE
AND INSIDE OF WELL CASING FOR
RETURN WATER TO OPERATE JET. TWO
IN. INSTALLATIONS MUST USE 1-1/4 IN.
GALVANIZED STEEL PIPE WITH SPECIAL
TURNED COUPLINGS (1-13/16 IN. O.D.) TO
AVOID RESTRICTING FLOW OF RETURN
WATER BACK TO JET ASSEMBLY.
1. Assemble the foot valve and packer to
the jet body.
2. Lubricate the rubber cups with
petroleum jelly.
3. Attach the first section of pipe and
lower jet assembly into well.
4. Add pipe until the jet assembly is
positioned 5 -15 ft. below the lowest
anticipated water level. The jet assembly
should never be closer than 5 ft. from the
bottom of the well or sand and sediment
may be drawn into the system.
5. With the jet assembly in position, fill the
pipe with water to make sure the rubber
cups are sealed against inside of the well
casing. It may be necessary to move the jet
assembly up and down to seat the cups.
6. Install the casing adapter and the
horizontal pipes.
7. Slope both pipes upward toward the
pump to eliminate trapping air. If the
horizontal distance exceeds 25 ft.,
see pump instruction manual for the
recommended pipe sizes.
For shallow wells (25 ft. or less), a
bolt-on shallow well jet assembly is
available as an accessory for deep well
pumps. The jet attaches to the front of
the pump with the two bolts provided
and converts the deep well pump into
a shallow well pump. The shallow well
jet assembly has a 1 in. NPT inlet and
a 1/8 in. NPT opening for an air volume
control. For optimum performance,
an in-line check valve on the inlet side
of the shallow well jet assembly is
recommended.
