This is my first spring with a REAL RV.  Please be kind as usual!

As I understand, dewinterize is drain / flush the pink stuff, sanitize with bleach, flush well and go camping.

My Suburban Water heater has a new anode rod, so I must replace and tighten before sanitize.  When I open the WH access, there are NO valves visible except the pop off valve.  Do I need to look elsewhere for bypass valve(s)?

It's not a dumb question if you do not know the answer.

The bypass valves are generally on the opposite side of the water heater. Sometimes you have to pull out a drawer, or remove a few screws and pop a panel. Just figure out where the back is inside, as compared with the front on the outside, and start digging.

True Preacher. Mine are inside the bedroom closet directly behind the water heater.
