Well water coming up through sink drain...
A few weeks ago, i heard this gurgling coming from one of my kitchen sinks (we have 2 separate ones in there), then clean water started coming up through the drain, after a few minutes of flooding onto my floor decided to cut the power to the well pump, and as soon as the tank was drained it stopped, a few hours later it drained completely and I turned the pump back on and it was fine. But now about every 2 days at the EXACT SAME time it does the same thing, i cut the power and run the water in the other sink to drain tank quicker, while scooping water from the flooding sink.
What could possibly cause this??
