Aft state room toilet is plugged and I have no idea how to unplug it. The pump is working properly. When I try and use well let’s say a stick to push things through it seems there is a solid barrier. I know there is nothing in there that hasn’t gone through my mouth first. I am the only one that has used that toilet recently. It flushed just fine last night. Any ideas on how to unplug the toilet? Everything is working properly, the water flows, the pump turns on builds up the proper pressure then shuts itself off. But there is still water and waste in the toilet. The flapper valve opens and closes unobstructed in the toilet but something between the flapper valve in the waist tube seems plugged. Any suggestions would be helpful please.
