How does a homeowner go about troubleshooting well/pressure tank system? I havent the slightest idea where to begin.

We have decent pressure for an older house with galvanized pipes but we seem to run out of water at times. If we fill the horse trough with a hose, we will run out of water after about 10 minutes. Not a drop from the tap!

I assume it has to do with the water table and an old well but it seems to quickly recover. Within 5 minutes of running out of water, we will be up and running again.

Any thoughts?
