Winterizing
I recently bought a 2008 Winnebago 29B and am curious about how to winterize it.

BTW, its important to know, winterizing an average rv takes about 2 gals of antifreeze.
If you find that you’re pumping 4-5 gals into your system, then your bypass valves are still open allowing your water heater to fill.
Think of it as a 6 gal thermos bottle with a cold water fill port and hot water out port. The idea of the bypass is to join your water lines by using petcock valves to bypass the WH.
After draining the WH , it’s ok to leave a small amount of water in the bottom of the tank, it won’t harm anything if it freezes.
Todays Pex lines are very forgiving, it’s the plastic inline elbows and petcocks that freeze and crack.
