When steel pipe is used to install the jet, be sure all pipes
are clean and the ends are reamed. Screw both 1-1/4" NPT
suction pipe and 1" NPT drive pipe directly into the jet body.
The special adapter nipple furnished with the jet is not used
on steel pipe installations, and should be discarded. Add sufficient piping, using pipe thread compound on the joints

2. Remove priming plug. Fill pump with water. Replace
priming plug. ff a priming tee and plug have been provided for a long horizontal run, be sure this line is filled
and the plug replaced, using pipe compound on plug
threads. See Figure 7, Page 7.
When the pump is to be disconnected
from service, or is in
danger of freezing, it should be drained.
The pump has a
drain cock which must be opened.
Remove the priming
plug to vent the pump. Drain the pressure tank. Drain all piping to a point below the freeze line.
3. Start the pump and run for approximately thirty (30) seconds. Stop pump, remove prime plug and refill with
water. Replace prime plug and gauge and restart pump.
Water will be pumped in a few minutes, the time depending on the depth to water and length of horizontal
run. If pump does not prime, check for a possible leak on
the suction side of pump. Check to be sure suction lift distance from water level to pump - does not exceed
twenty (20) feet.

A good way of delivering gas-free water is to suspend a pipe,
closed at the bottom and open at the top, surrounding
the
suction pipe (Figure 14). Since the gases rise in tile well casing, the water sucked clown through
the pipe and into the
suction pipe is free of gas. It is imperative

HOW TO AVOID OVER-PUMPING
A SHALLOW
WELL
In the section on Priming
The Shallow
Well Pump, Page
10, the instructions
were to open the pressure
regulator
all
the way after the pump starts to deliver water. If you are
over-pumping
your well, however,
you can partially close
the pressure
regulator
on your SEARS jet pump to increase
the pressure
and reduce the delivery.
