This weekend we did a shock on our ~350' well to address some iron
bacteria issues. Followed instructions carefully, adding measured
amount of bleach and recirculating well water via garden hose back
into the well head. Then we ran each faucet slightly untilI we could
smell chlorine, turned it off, turned off the well circuit, and let it
sit for the night.
The rest of the process was to run things out via hose the next
morning, so as to not compromise our septic system. However, when I
got up, I found that our pressure tank showed 0 psi. When I turn on
the well circuit, I can hear the pump humming, but no water gets
delivered to the pressure tank.
I took off the well cap again and powered the well circuit. I can
hear "activity" in the well, not just the distant vibration or hum.
With the echos and such, it is impossible to tell what that sound
really is.
It seems to me that somehow I have lost the seal prime on my well pump
(or have a hole in the delivery pipe) that is preventing the water
from being delivered. Anybody know of a way to diagnose this issue
without special equipment? I believe the pump is at least 300' deep,a
nd has worked flawlessly for years.

There is no prime on a deep well submersible to be concerned about. I can't
imagine anything that you could have done to cause a problem, but I would
check at the well control box to see that you have 240 volts to that point.
Sometimes there are splices made under the sanitary cap of the well head.
Check and be sure that they are all tight as well.

Very strange. You say the pressure was 0 in the morning, but what
was it when you turned off the pump? If the tank was at normal
pressure when you turned off the pump, did anyone draw water which
would account for the pressure dropping to zero? If it went from
normal pressure to zero on it's own, it would indicate a failure in
the pipe or check valve stuck open. A check valve failing to close
would account for the pressure drop, but not result in failure to pump
water. That would seem to leave a pipe failure as the likely
culprit, but why it would fail due to chlorine treatment doesn't seem
to add up.
Is the pipe steel or pvc? Even if it's steel, old and it were
deteriorated, it seems improbable that chlorine could finish it off
overnight to the extent that it would have a gaping hole. How much
chlorine did you put in?

You can hear a pump at 300' deep humming?? Good ears :)
1. Check the pressure switch. Zero pressure means the switch isn't doing
its job in some manner.
2. The pressure switch probably goes to a relay. Relays generally have a
manual start button, often on the bottom exterior of the case. Does pushing
it start the pump and deliver water? If not, have the start capacitor
inside the case replaced. If pushing it starts the pump and the zero
pressure re-occurs, the start capacitor is flaky...have it replaced. The
one I just had replaced yesterday cost $35 + the service call..

How is that remarkable deduction made? It would seem to the rest of
us that there are many possibilities besides the pressure switch.
