3. If pressure does not build up after priming pump
several times, check the following:
a. Suction pipe in the water.
b. Suction pipe has no leaks.
NOTICE: Air can leak in even where water won't leak
out. Make sure all joints are tight.
c. Control valve, check valve, or foot valve installed
and operating correctly.
d. Pump trying to lift water more than rated lift for
deep well ejector used (including compensation
for horizontal offset).
e. Be sure pump is not airlocked. In offset install-
ations, pump suction port should be highest
point in suction pipe; there should be no sags in
suction pipe (run it straight and at a slight angle
upward from well head to pump).
4. Once unit has primed and pressure stabilized,
slowly open (turn counterclockwise - Figure 16A,
regulator valve until pressure falters (pressure
gauge needle flutters; pump may become noisy - see
Figure 16B). At this point, close (turn clockwise)
regulator valve slightly until pressure stabilizes. This
setting provides maximum flow (Figure 16C).

5. Pump may draw well down far enough at this point
to lose its prime. If so, close regulator valve until
pressure is stable throughout pumping cycle. Close
faucets and allow pump to pressurize tank and shut
off.
6. Check system by alternately opening and closing
faucets in the system. With faucets open, pressure
will drop until pump starts; with faucets closed,
pressure will build up until pump shuts off.
7. There are conditions of deep well operation when
the regulator valve may be completely open with-
out any faltering of pressure. In this case, operate
pump with regulator valve open.
HELPFUL HINTS / MAINTENANCE
How To Handle A Gaseous Well
In some areas well water contains gases which must be
allowed to escape before the water is used. To deliver
gas-free water suspend a pipe, closed at the bottom and
open at the top, so that it surrounds the suction pipe
inlet. (See Figure 17). Since the gases rise in the well
casing, the water sucked down through the pipe and
into the suction pump is free of gas. This type of well
must be vented to the outside of any enclosure.
Air Control In Flowing Wells
Flowing wells or wells with little or no drawdown,
could create a special problem in air control in the op-
eration of your standard tank system. In such cases, a
pre-charged tank (which needs no air control) is
recommended.
