Xylem IM126R02 E-Z Prime Jet Pump Shallow Well Jet Pump - Manual (Page 4)

The ideal depth of the well screen will be three to
five feet below the static water level; however, do
not drive the point below the water bearing forma-
tion. Before starting a drive point system, always
make sure that the water bearing formation is less
that 25 feet deep. If it is greater that 25 feet, a deep
well system will be necessary.
5. Horizontal piping from the pump to the well should
be as short as possible to avoid increased friction
losses. For most efficient operation, the suction
pipe should not be smaller than the 1-1/4-inch suc-
tion port on the pump. Table B shows the correct
pipe sizes for horizontal runs. If the pump is being
installed offset from the well, the piping should
pitch upward from the well to the pump about one
inch for each 10 feet of pipe to prevent air pockets
in the line. Plumbing should be below the frostline
or otherwise protected from freezing.
6. Attach appropriate 1-1/4-inch tee or adaptor at the
junction of the horizontal and vertical suction pipes
as show in Figure 1. The tee can be used to clean
the well.
7. It is important to clean the well of sand and muddy
water to prevent damaging your pump. Clean the
well by inserting a garden hose down the well pipe
and surging water into the well. Wait until the water
flowing out of the suction pipe is clean.
Section 2
Installing or Replacing an
Existing Shallow Well Jet Pump
For your safety, turn off the electri-
cal power supply at the service en-
trance before connecting or discon-
necting any wiring to the pump to
avoid any possible electrical shock
hazard.
1. Drain the holding tank. Also disconnect the suc-
tion pipe, the service line, and if necessary, the air
volume control line. Remove old pump.
2. Place the jet pump on a level, solid foundation. If
you are also replacing the existing pressure tank,
refer to the “Pressure Tanks and Piping” section in
this manual.
3. Connect the suction pipe, the service line, and if
necessary, the air volume control line. Use either
non-toxic pipe sealing compound or tape on male
thread joints of galvanized pipe (tape or cement on
plastic pipe) to facilitate making air-tight joints.
4. Wire the motor.
Pressure Switch Attached
The Red Jacket jet pump is wired to the
pressure switch. The pressure switch must be
grounded in compliance with the National
Electrical Code and local codes and ordinanc-
es. It is mandatory that a ground connection be
made using a conductor or appropriate metal
underground water pipe or a ground lead in
the service panel.
Pressure Switch Supplied Unassembled
Direct wiring instructions can be found by
following the wiring instructions on the inside
cover of your pressure switch. For the attach-
ment of the pressure tube and fitting see
Figure 2.
5. Prime the pump.
a. Remove top priming plug.
b. Open faucets on downstream side of the pres-
sure tank so air can be purged from the system
while priming.
c. Pour water into the pump case until it flows
freely out of the priming hole without air
bubbles.
d. Replace priming plug, leaving the plug loose
enough to allow the air in the case to bleed off.
Turn power on. Start pump. Water should be
pumped in a few minutes depending on depth
of water and horizontal piping length.
e. After water is pumped, close faucets. Sufficient
pressure should build up and shut the pump
off.
6. Disinfect the well using a cup of household bleach.
Let the water stand for a few hours. Test it for purity
with the local Health Department before using.
7. To assure continued primability, tighten all plugs to
prevent air leaks.
8. If the pump does not operate properly, refer to the
Troubleshooting Section in this manual.
