Operation (Continued)
b.Be sure pressure regulator, check
valve, and foot valve are installed
and operating correctly.
c. Pump may be trying to lift more
than rated lift for deep well
ejector used (including
compensation for horizontal
offset).
d.Be sure pump is not airlocked. In
offset installations, 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).
NOTE: For deep well installation, go to
step 4. Shallow well installations go to
step 6.
4. Once unit has primed and pressure
stabilized, slowly open (turn
counterclockwise - See Figure 9A)
regulator valve until pressure falters
(pressure gauge needle flutters;
pump may become noisy - See
Figure 9B).
At this point, close (turn clockwise)
regulator valve slightly until
pressure stabilizes. This setting
provides maximum flow (See Figure
9C).
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 without
any faltering of pressure. In this
case, operate pump with regulator
valve open.
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 10). 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 operation
of your standard tank system. In such
cases, a pre-charged tank (which needs
no air control) is recommended.
