Could you please explain in more detail what is meant by the “action of the annode causing the brass nipple to plug”. If not brass, what kind of nipple should I use to attach to the tank? As far as the circulation question, has anyone ever used a mono-flow tee (mounted backwards) in this situation? The only two problems I can think of would be reduced capacity of flow through the 3/4″ and when water is being drawn, it would force hot water to the bottom of the tank. I can’t see where that would be a problem. When the tank is idle, gravity would force the hot water from the side arm, back into the tank. Let me know your thoughts.
