Just installed a new jabsco big bowl toilet last year .( I know should have got a Raritan but they were on good sale price ). When I pump with water there is no issue but when I flip to dry there is back pressure on the pump handle. Also get air pressure back through he joker when stopped pumping . Removing the waste cap does not change anything.
Tried spraying water down the vent but no change. Could it be the vent plugged or something else plugged .
