Tony,

Your pump, holding tank, and household plumbing make a pressurized
system. Taking off this cap is like opening a faucet, water flows out. As
the water flows out the pressure in the system drops. At some point the pump
comes on. So turn the pump off and the water will stop gushing out but you
may lose the prime on your well. So have a couple of gallons of water just
in case.
Are you sure of the location of the pump and any check valves? You can't
shock a well if there is a valve blocking the path where you intend to pour
the chlorine.

Sorry but that is wrong. Wells in a standard system are not part of
the pressurized system. He has an artesian well, i.e., the aquifer his
well tapped has enough pressure to force the water to the surface.
That may be a seasonal condition or year round. Taking that cap off
should have no effect at all in his pressurized system.

Hi,
One thing, this area is called 7 springs. Historically never suffered
drought.

Okay, that explains it. You -do- have an artesian well and the
overflow with the cap off is quite normal.
