First time motorhome buyer where is the water heater bypass?
I have a 2007 Four Winds Hurricane and I can't find the water heater bypass. I've winterized it and this is the last step.

On a related note, a plumber friend of mine says the pex lines we have can freeze about 4 times before it has a chance to burst. Has anyone else heard that?
Lines that can flex are less prone to breaking.
But it's all about pressure.
If the line is essentially open at both ends so that the freezing water can expand down the pipe unobstructed, no pressure builds up an d no pipe damage occurs......usually.
Theoretically, if you open all the valves and faucets everywhere in the system and leave them open, the water in the lines can freeze without causing damage. Theoretically.
Now the pump itself is another matter.
