A shallow well system should not be installed where total suction
lift exceeds 25 feet at sea level. Suction lift must be reduced at
the rate of approximately 1 foot per 1000 feet at elevation. Total
suction lift consists of the vertical distance from the water level
when pumping to the pump plus losses due to friction in the pipe
line. The volume of water delivered decreases with an increased
suction lift.
Drilled, bored or dug wells may employ an arrangement as in
Figure 1. Driven wells and sandpoints employ the configuration
in Figure 2.
1. a) Install a foot valve on the bottom of the suction line and
place it 5 to 10 feet below the draw down level, that is, the level
of the water when the unit is pumping its rated capacity. It should
be far enough from the bottom of the well to avoid pumping sand
and mud. (Figure 1)
b) On driven well installation, install a spring dog- check valve
on the vertical pipe at least five feet above the well point, or in-
stall a horizontal check valve in the suction line near the pump.
(Figure 2)
2. Check the foot valve, see that it seats properly and that no
obstruction prevents its opening or closing. A leaky foot valve
may cause excessive cycling (motor starts and stops).
3. Lower first length of suction pipe, with attached foot valve
into the well, fill pipe with clean water. If water recedes a leak is
indicated. If no leaks occurs, assemble the remaining section(s)
of pipe and check again for leaks.
4. Install the well seal at the top of the well casing and tighten
well seal bolts. (Figure 1)
5. Install a tee at top of suction pipe, with a plug in the top
opening, and connect through a union to the female thread in
the pump body.

6. Connect pump discharge to pressure tank, and pressure tank
to house plumbing.
7. After piping is completed and motor is properly wired,
remove the priming plug on top of pump and fill pump with clean
water. Allow time for air in the system to escape, and refill pump if
necessary before replacing the priming plug. Start motor and the
unit should operate. If it does not, it may be necessary to reprime.
8. When unit has built up to maximum pressure, and has
automatically stopped, check all piping both suction and
discharge lines for leaks, as they will be under pressure.
NOTE: If the unit is to be used with a vacuum type air volume
control where the source of supply is on a level with the pump
or above it (artesian well, pond, cistern or shallow well with less
than five feet lift) a valve should be installed in the suction line
that may be partially closed to cause the pump to operate under
a moderate suction lift of 8-10 ft. to insure correct operation of
the air volume control which is operated by vacuum.
