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.
