Our well was drilled in 1983 and wasn't allowed in a pit.Got it, thanks. To clarify, the pressure tank is underground in a cement "room" so I guess that is what keeps it from freezing?
This morning both houses have clear water.
Both houses were built in 1987. Maybe code was different then, but both houses share a well and pressure tank.
I would like to get the water tested but seems all the labs are shutdown around here due to coronavirus.
