Sorry I don't have any data about depth of well or any other history of it. Trying to help out an elderly friend and they are not very clear on some details.
Water meter shows about 0.10 gallons per minute of usage even when everything (as far as I know) is turned off. Is this amount of usage likely to be problematic on a private well? Recently the well ran out of water* and I'm trying to decide whether it's worth chasing down this leakage or if the problem is likely to be elsewhere.
*details on how I know it ran out of water: pressure would be ok for a bit and then drop to zero. After leaving the master valve off for a while we turned it back on and listened at the well casing. We could hear a very dull hum for a while and then a much louder one that sounded like the water level had dropped to the level of the pump.
Other possible reasons it might have run out:
1 - local water table conditions may have changed due to recent development across the road and lower-than-normal rainfall last couple months
2 - tenant could have done something crazy like take an hours-long shower. No reason to suspect anything but not completely trusting them either
In case you're wondering why there's a meter on a well: it's because that's how they pay for their sewer bill: private well but public sewer.
