We realize that we'll have a lot of sanitizing the fresh tank next spring but couldn't get the trailer into dealer any sooner. Later we finally discovered the valve under the bathroom sink behind the water pump that you can't visually see. We pumped more antifreeze though the system and it works correctly. Our more difficult issue was draining the water heater. We used the bypass to ensure no antifreeze got in heater but could only drain water using top release valve. We finally were able to get a large enough fitting to remove the bolt at the bottom that holds the heating element and it didn't seem to have anymore water. Does anyone know an easier way or is there another easy to drain the water heater?
First off all, that's an anode rod, not a heating element. It's something you'll want to remove and inspect at least 1 or 2 times a year. It will eventually wear out. So having the tools and know-how to take it out is a good thing.
Second, removing the anode rod really is the fastest way to drain the WH.
Lastly, that valve at the top is the pressure release valve. You want to use that to be sure there is no pressure built up in the WH before you take the anode rod out. If you don't, you'll certainly get an unexpected shower.
