Waste Tank Valves June 02, 2024, 02:38:32 pm This is BIG. Replaced the old valves. I gotta say this was a pleasurable job. On our other rigs, it was much more complicated. Had to take off a panel, undo electrical stuff and then twist around to do the valves. With the LD, n o prob!!!Also noted that one of the pipes was loose so good luck on that.jor 3 Likes
