Today the change the angle of the 4” piece of tubing and raised it about an inch. Drove home and it appears to have worked. Will want to test more before any cheering. What I am still questioning is what part the gravity fill port might have to do with this.
The spill will continue till the water level drops to the vent port. Running the vent up hill by 1" will reduce spillage a bit. If the trailer leans to the side where the vent is connected, the spill will start, if leaning the opposite way there will be no spill.
A gravity fill system has a vent and fill pipe well above water level and that is why they work. A pressure fill system needs to have vents well above water level, but that would cost a few dollars that the manufacturers will not spend.
The manufacturer that I fought with changed back to gravity fill to fix the problem, but they still have no clue why water only runs downhill.
If you think that your problem is fixed, have a car follow close behind on a curvy mountain road so they can record the spillage. Yes, I did that.
I feel your pain. However I did not try to figure out what was causing the siphon. I really have no desire to remove the underbelly to get to the root of the problem. I am not located near the factory.
I simply put shark bite valves on the vent and overflow lines to stop the water loss. Yes I have to remember to open the lines when I get to the CG. Kind of a crude solution but it works for me.
