Been in house about a year, recently found water coming from carrier pipe between well and pump house. When we first found it about a week ago, pressure tank had water like normal, now tank is empty, air pressure is normal. Haven't noticed any issues with water pressure in the house. Some posts I've read point to possibly a bad check valve, but I don't see a check valve in the current setup, possibly down in the well? Would adding a check valve in the supply line or between the pump and tank help?

Any help would be appreciated.
