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 falteling
of pressure.
In this case, opec-ate
pump
with regulator
valve open.

How
To Handle
A Gaseous
_N'enH
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
thi°ough 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 Nowing
WeIBs
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.
Using
the
Compound
Gauge
If the pump
or system
seems
to be operating
ineffi-
ciently, the compound
gauge
can sometimes
help de-
termine
the problem.
A compound
gauge is a combination
vacuum
and pres-
sure gauge which will indicate
(1) receding
water level
in the well, (2) leakage
in the suction
line or in the
pump,
or (3) clogged
impeller.
To use, install the gauge in the air volume
control
(AVC)
port
in the base of the pump.
Open
all shutoff
valves
between
pump
and household
piping.
Tighten
regula-
tor screw as far as possible.
After running
pump
a few
minutes
to eliminate
a!l air from pipes,
loosen
regula-
tor screw until compound
gauge shows
15" of vacuum.
This setting indicates
that the pressure
regulator
is set
for delivery
of the highest
volume
of water
possible.
Let the pump
run a few minutes;
if the water
level in
the well is falling, the vacuum
will increase,
ff neces-
sary, reduce
the regulator
setting
to b,ing
the vacuum
reading
back to 15". If the pump
does not develop
15"
of vacuum
according
the gauge, you may have air leaks
in the suction
line or a clogged
impeller.
Cleaning
the Deep
Well
Jet
1.
Disconnect
power.
2.
Disconnect
piping
and well seal or casing adapter.
3.
Withdraw
jet assembly
from the well.
4.
Unscrew
and remove
the venturi.
Remove the noz-
zle with a socket wrench
and clean.
5.
Replace
all parts, reprime,
and turn on power.
