Fresh water vent siphons?
I vaguely recall hearing something about a known issue with the vent lines from the fresh water tanks.
Before our last trip I added 40 gallons of fresh water to top off the tanks before a long stay (six days in the boondocks). Both tanks started flowing through the vents and it created a siphon that kept draining for about a half hour. After that I turned the hose down real low to replace the water that had barfed out and was able to fit almost 70 gallons back into the tank.
I assume the fact that the vent lines hang down so low is what's causing the siphon. I don't want to trim them without checking here first to find out if this is a known problem and what the recommended remedy is.
