First leak happened July 2012. Only way to know it is when you get the $3,500 water bill from hell. Line is 2,000 feet from meter to house. Property is desert. No way to find leak until water surfaces which took almost two months. Could not cut off water since $100k of landscapping would die, and pool pump would tear up. So, had to have water on for couple of hours each day for second month. Second month water bill $2,500. Digging five feet deep under road to find line and repair was $2,800. Second time it happened was July 2013. Same scenario. Total costs so far, $15k. Replaced line August 2013. Cost $15k. Total costs $30k
