It's basically a widget that goes onto a fitting opening on

the side of the tank, about half up, ie at where the air level

should be. It has a float or similar inside it that reacts to

the water level. If the water level gets above the level

of the tank fitting, it triggers a valve in the widget to

open which is connected to the suction side of the pump.

That allows a small amount of air to get sucked in. Each

time the pump runs, that process works, until the air level

is back to the level of the widget.

Hmmmmn....concept ok, execution here would be _really, really_ tough as

it's 2-300 ft from well house where the pressure tank is and the well...



Yes, I guess I should have mentioned they only work on
jet pumps where you have the suction side of the pump
near the tank. Which is probably why you don't see them much
these days. Years ago, many wells were shallow. With a
submersible they can't be used.








... Each time the pump shuts off the water is drained between the

bleeder orifice,which is about 5' down in the well on the drop pipe,

to the additional check valve at the tank.
