Black Tank Drain Issue-Solved
I had issues with black tank not draining properly since my 2006 335RLT Sandpiper was new. Only way I could get it to drain has been to use my Flush King to back flush multiple times. Needless to say it's been a PITA. After my last trip I decided it was time to "Go In". Took the camper to a dump station and flushed it for about an hour. Then let it drain until not even a drip came out. When I got home I removed the black tank valve. All four bolts sheered off. Replaced them with stainless.
From reading this forum I knew this is what I would find. The pics tell the story...yep, the disc from the toilet cutout "will not" go through the valve. Problem solved!
