The good news is that the problem has been fixed and it could have been worse. By cutting into the water line at intervals we were able to narrow down the leak to a portion of our water line. Rather than try to find the leak and repair it, we decided to dig and place a new line for that portion. Because of property lines and geographic issues - did you know that Blount County has a lot of rock? - we couldn't do a simple straight line. A lot of trench digging (no, not manually, thank goodness!) and laying just under 300 feet of PVC pipe later, the work was completed and we had water again. Whoohoo!
I hope everyone is enjoying their 4th of July festivities. We are taking it easy, lol.
