If you turn the handles of your valves on the water heater lines so they point to the bypass line between them I bet it'll bypass the heater. Same deal on the water pump too, it'll block out the fresh tank and draw from the clear hose when turned the other direction.
If that is what they are using then we will have to update our winterizing page, folks will undoubtedly get confused now with the differences in the new and old systems. Thanks.

Too late, already confused...lol! This stuff changes so much from what I hear, it would be hard to stay on top of. The diagram fits my situation to a tee. Thanks everyone for your expert opinions. It's great to know that this forum exists for beginners like me.

I have the new 1 valve setup at my pump under my sink but the conventional 3 valve system at my water heater. I guess they decided to change over in the middle of my build!

Just a quick update, winterizing completed. I closed the two valves by the water heater and opened the valve by the pump and everything worked fine. So, to recap, mine does not have a bypass valve or a separate valve to close off the fresh water tank. New system I guess! Thanks everyone!

I looked on YouTube and watched lots of videos but most I watched, the hot water tank has a bypass valve but on mine I don't see that (pic attached). I was thinking that all I would need to do is turn both the valves off but I don't know for sure?? Also, under my sink in the kitchen is my pump and clear hose to place in the antifreeze jug. I see one valve (attached pic) which looks as though this valve is for a water line going in thru the floor but I'm not sure where that line goes??

Just need some expert advise here!

Thank you

Just an observation from your picture. Do yourself a favor and plug up those large holes in the floor where the wires and water line pass through.

Mice love to come in to RVs in the winter and these holes are a perfect place for them to get in.

Jayco did a terrible job in my 2015 Eagle and left large gaping holes all over. I used Dow Great Stuff Pestblock foam to close up numerous places where the mice got in.

You will find other large holes where drains, vents, wires and water lines pass through the floors.
