Most of the 'vented' cap issues seem to be related to suction (vacuum) when the cap is removed. Mine is opposite and it's building enough pressure in the tank that the cap pops up when opened. Is it normal to build this kind of pressure? The cap is fairly new and allows air in with suction, and blocks air from exiting. Anyone remove that check valve and how did you do it? Tnx.
