Why do I need to adjust the water heater bypass valve to use city water?

[Snake Plissken]

I normally stay ay state campgrounds and fill my tank when I arrive. I'm staying in a private campground this weekend and my manual tells me to do this. Why?

Oddly enough the picture in my manual mad eit very easy to find these valves. It's the only "clear" thing from the manual so far.

Not sure why you would have to do this unless your setup is different then mine. I never have to touch those valves unless winterizing/dewinterizing. If I use the city water I just do not turn on the waterpump.

I do not know why the manual would be saying this. the only water heater bypass I know about is for winterization. You turn the valve or valves witch bypasses the water heater so you can drain it and not have to fill it up with antifreeze.

Maybe I'm misunderstanding the manual. Here's what it says:

The normal position is the one you use while camping with city water or pulling water from the tank. The manual is just saying to check the bypass valve incase you just pulled out of storage or something like that.

Great...thanks!

Even in the Jayco line, there are many different configurations on water. It would pay to look at the directions on the water panel or your owners manual to verify you are operating valves or inputs specific to your rig.

These directions are for first time use or first time use after winterization, or first use in the spring. It just means to make sure to UNwinterize the system, before use.
