Unfortunately the warning signs of a failed hot water tank are not always subtle. We often arrive at water heater change outs with wet vacuums and trash bags in hand. Floors are ruined, insulation is saturated and personal belongings are destroyed. To help avoid the havoc caused by a burst hot water tank we now recommend automatic water leak detection & appliance shut-off systems with every new water heater installation. LeBlanc Heating offers a flood control system that sounds an alarm and automatically shuts off the water supply to water heaters when a water leak is detected. Because the water flow is stopped at the source the damage radius is minimized or completely eliminated.
