A few months ago I noticed an uptick in water usage on our sheep farm. I figured it was due to a bigger flock or more water use in the shop. My mistake. By last month the volume was alarming, so I alerted Bob (who can now monitor and pay the utility bill).
He called the plumber who determined that the oldest water line behind the barn was leaking. In my defense, there weren't unusual puddles behind the barn. We have been droughty the past few years, so any extra water just soaked in or ran underground to the alfalfa field, pasture, and pond.
Workers came this week with a backhoe to dig out the line and install new hydrants in the barn. Pricey problem.
