We bought a water heater from Water Heater Pros in Oct. 2012.  Recently we noticed the pipe that leads up and out of our garage had become disconnected.  We called them and the same morning they came out and fixed it at NO CHARGE!  Warranties for the water heater is good for 2 years and the parts are under warranty for 6 years. We will definitely contact them again when this water heater needs to be replaced.
