I have a CSY37 and the Fiber glass water tanks
swell up like a Balloon when I fill then to full. There is a 3/4"vent overflow about two inched from the top of the tank on the forward side next to the Fill but no water
comes out until they are completely filled but at that point they start to Balloon and it is causing all kinds of stress problems / leaks
etc. I think I need to move the Vent higher but can't put it out of the top because there is no room. it seems that there is a Air pocket at the top causing this problem! Should I punted a vented loop in ? but I donít see how that would solve the problem! Any body with any Ideas would be most appreciated???
