In flushing the rv antifreeze out the hot water system I heard a lot of water coming out underneath the rear of my sprinter 3500 class b motor home. The best I could see at the IW60 water heater there were two hoses coming out of the bottom right. I am thinking that the water is coming from the right hose (frost protection value?) To the left of that hose is another hose another hose that appears to be a system drain hose. The Heater is heating the water. Turning the valve off for the cold water inlet, stop the flow from underneath the motor home. This heater is at the rear of the Midwest Automotive Designs 2017 Weekender. I am located in Murray KY and is there a recommended service center near me
