Black water tank pressurizing?
hello all, new to the forum. We have a 2007 Cardinal and after emptying our black water tank this past weekend (and using the power flush to rinse it out), we are experiencing an issue with our toilet where when you flush, an air bubble appears when you depress the foot pedal. Even with the black water valve opened, it is still acting like the tank is not venting properly. Has anyone experienced something like this? Does anyone know if it's possible for the vent to get clogged? Any information will be greatly welcomed. Thank you
