My well is 6" diameter, 470' deep. I don't know what the static level is. I have an 84 gallon pressure tank protected by a pump tec switch. When the water goes out, and the tank is completely empty, it takes about 2 hours for the well to recover enough to fill the tank to 60 psi. The confusing part is when the water runs out. Some times it is obvious, lots of laundry, long showers, etc, but sometimes it it totally unexpected. We are very careful with out water use, so this happens only two or three times a year.
