How do you mean, bypass the water heater?
If it is heated by the engine then the engine side will have antifreeze in
it (won't it?).
But the other side is your washing-up and showering water. You cannot put
antifreeze in that and if you just bypass the heater it will freeze and
burst. I am going to drain that side of mine and see no other option for the
winter.
What exactly are you planning to do?

Anyone familiar with PEXtite systems?

After getting a close up look at my plumbing, I'm considering some changes
and mods, like a bypass on the hot water heater for winterizing purposes.

Looks like it's easy to work with. Just need to find a local supplier.
