Anytime I have ever had this problem on a pump, a replacement of the air
volume control on the tank took care of it. Quick and easy to do. One of my
Myers pumps ran 23 years before it had a problem, then it was the air volume
control. I think I got my money's worth on that one.

Some how the water tank loses the air in the tank. After a few months
the well pump starts to short cycle. At this time I remove the plug
that is about halfway up the tank and drain the excess water
out.replace the plug and everything is OK for a few months more.

I can find no where for the air to leak out. It seems like it has to
be at the top of the tank, above the plug that I remove to drain out
the excess water. I don't think that it is the drain plug because as
soon as it gets below the water level if there was any leak, it would
then be water, and I dont see any wet spots.

Any Ideas would be appreciated.
