Hello guys! So this is my first time in a camper ever and I have a summer job and the people I work for provided me with a camper. I?m not sure what kind it is but the toilet is a thedson aqua magic I think? Anyway the toilet started not flushing all the way like things will leave the toilet bowl and then stay right under the little toilet flap like I can see he toilet paper and stuff when he flap moves when I flush he toilet. I thought the problem was the tank being full so I just had that dumped but the excrement from before is still there under the flap! How do I make it ?go down?? I would rather not have to call someone to help i would like to do it on my own as my employers own the thing... thank you so much!!!!
