I finally have gotten around to finish up the vent system with overflow in hopes of preventing water loss due to sloshing. First I wanted a locking water gravity fill so that was installed a couple months ago. An adapter had to be used since anything coming in from across the pond is not standardized. In this case the gravity fill is 1 1/2 inch and the fill line is 1 3/8. Go figure.
The modified overflow has been in place for a couple years. Yes things move slow it seems.
The modified overflow with ball valve has been tee'd into an overflow that connects to the gravity fill. I have no issue closing the ball valve during travel, but forgetting to open it once we are camping could be devastating to the tank due to collapse. The vent will prevent that issue. So consider this an old age tank damage preventive device.
I will be testing this tomorrow to see how much water is lost since I expect some may slosh out of the small vent line. This can be improved by extending the vent as far under the kitchen cabinet as possible, and back down to the gravity fill. Since the drawer slides are like razor blades, I decided to take the easy route as an initial test and connected it directly.
