I was reading somewhere about winterizing the H2O heater. I don't remember where I read it but it said to put some RV antifreeze into the water heater via the bypass valve when winterizing the rig. It stated that there is always about an inch of water left in the water heater and that needs to have some anti-freeze added to it. I have never heard of this and from what I've done from experience and picked up from the forum that is not needed. I frankly don't agree with this but what's your take on this? Inquiring minds need to know!!!
