Water Heater Leak (Update)
I got the water heater out and the tank bottom was a rusty mess. The Styrofoam was stuck to the tank and would not come off whole. I rinsed it at the beginning and end of the season and changed anode rods as needed. I'm sure it was some other type of error on my part. Has anyone switched out the Suburban for an Atwood? It looks like the Atwood has a glass lined tank to prevent this in the future. Any input on dealers to purchase from?
