Winterizing issue: faulty water heater bypass?
While doing my annual winterizing of our coach I was puzzled that though all the faucets and ice maker were closed the water pump when turned on drew up from the attached jug of RV antifreeze. Thinking the only place for the fluid to be going was into the water heater I then drained it and indeed found there was antifreeze in the water heater water. This was despite the fact the left value was properly set to "bypass". Could it be the valve is not functioning properly? This would seem to me to be extremely unlikely, but I can't understand how else the antifreeze could be getting into the water heater when the valve is thus set.
Thanks in advance for any thoughts.
