You really should unstick it and reinstall.

Yea But, yea BUT,, THe rinse line (back flush) isn't connected to the water lines. All it does is goes from the black water tank to the hose bib located at the sewer valves and is used to back flush the tank. How does it suck anything from any other water / drain line ? It can't. I talked to the guy at Lazy-Days (Thor )parts counter and he didn't think it would be a problem to install a 90 elbow and loose the valve ? But of corse he wasn't sure ???
