I had an issue with my hot water heater needing new heating elements and/or being replaced every few months. Bobby came out and fixed it again and determined that there must be a cause - Jerry came out within the hour to see if there is a slab leak. Took him minutes to determine that we are running out recirculating pump too long - essentially cooling off the hot water constantly and taxing the hot water heater. Love these guys!!!!! They do a great job and they are trustworthy.
