i have a 2010 winnebago class C and are having issues winterizing the system. After i flushed out all the water from the holding tank and the faucets are dry i move the bypass to the aintifreeze and when the pump gets turned on the system immediatel...
The water heater valve is at 12 position, it should be off. If it were going into the water heater wouldn't that mean that the antifreeze should not go in the overflow outside? How can the system flush fluids outside? This is what is puzzling me.
