Short cycle

This is the part in the well.

Thanks! I got just swamped this afternoon.

Another view.

End of job. Just turn the water on. This is at a hunting camp with no buildings.

The AW8A can be seen at the web site below:

However you describe that the pressure switch is and has always been under the house so I doubt that you have the AW8A.

You will need to completely disconnect the old tank because I believe it is leaking water. I doubt that the pitless adapter is leaking however if you want to look down the well, use a small hand mirror and focus the sunlight down the well. You should be able to see if it is leaking.

If the pressure continues to drop after disconnecting the old tank it could be that the pump check valve is leaking back. However I doubt it.

NOTE: It's always best to have the pressure switch mounted near the pressure tank.

I suggest that you look up http://www.cyclestopvalves.com/pdf/psidekick-brochure.pdf it will show you how the pressure switch is near the tank.
The Cycle Stop Valve gives you constant pressure like city water pressure.

Thanks to everyone for all the replies and info, we ended up getting a well guy to come out. He replaced the check valve at the pump and so far it is now holding pressure. His take on it was to try that first because it was less cost than digging up the old pressure tank. If replacing the check valve did not work he was only going to charge for digging up and replacing the tank. Sounded fair to me.

I don't remember, do you have a submersible pump (in the well) or a jet pump (above ground)?

You say he replaced a check valve. Did he or did he add one?

If a jet pump, then he should have pulled the drop pipe and replaced the foot valve because adding a check valve hides the leak and the leak can get worse and cause problems like dirty water etc..

Could a faulty foot valve have the same symptoms ?
