Possible Bad Check Valve or Inside Monitor
DRV Tech Support seems to feel my inside monitor is spot on accurate. They feel that the VENT, Fresh Water Tank, overflow, etc are operating as designed and as they should. I don't really understand why a Fresh Water tank needs a bunch of internal air to operate properly, but DRV says that at least for my model & year it does. I was surprised that 70 to 85% full was considered as full as the tank should ever be. I guess I have to accept the system as it is if it is operating as designed.
Do you all disagree with DRV's assessment?
