I have a 2018 Hurricane 29M. It has an outside sink that uses a pump to evacuate the bowl and feed the waste into one of the tanks. Which tank, I don't know and don't care, right now at least. It has been backing up and not pumping out well. I took the waterless trap and the pipe to the pump out, cleaned out the smutz and put it back together. It worked for a while but now is intermittent. The pump runs but does not always drain the bowl. My question is does the collapsible sleeve in the waterless trap wear out causing the pump to loose its prime?
