HELPFUL HINTS

How to Handle a Gaseous Well

In some areas well water contains gases which must be at- lowed to escape before the water is used. This can be done as shown in Figure 18.

Figure 18

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 in air control in the operation of your water system.

In such cases, install a Captive Air* Tank. It does not require any air control.
