Arrived on site and customer stated that he had a large increase in his water bill that went from $40-$400 in two months. He stated that a few days prior as he was out of the state, the water company came down and shut the meter off as there was a leak on the main line outside. Upon my inspection, I turned on the meter and noticed right away water on a valve just after the meter. I quoted the customer to dig up and expose the line and repair the leak. I went ahead and removed the broken ball valve and made my repair. After repair was made, I re-pressurize the house and kept an eye on the meter to ensure the leak was fixed.
