Call for high water bill. Arrived and met with Willie and he showed me a water bill that was 3-4 times higher than normal. When performing a cursory inspection found a toilet with a fill valve that was adjusted too high, allowing over filling of the toilet. Once it was adjusted down water has stopped passing through meter. I also found that the water heater on site is 20 years old, and has a failed thermal expansion tank. I recommend replacing this immediately, as it is far over its expected life span. I recommend contacting water service provider for a bill adjustment.
