HELPFUL HINTS
How to Handle a Gaseous Well
In some areas well water contains gases which must be al/owed to
escape before the water is used. This can be done as shown in
Figure 14.

J. Reposition capacitor and replace motor canopy.
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.
Since the gases rise in the well casing, the water sucked down
through the pipe and into the suction pipe 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 ha air control in the operation of your water system.
In such cases, install a Captive Air® Tank. It does not require any
air control.
