Black Tank Flush out
Posted: Fri Nov 20, 2015 8:52 pm
We purchased a used 2010 3450 RL recently replacing our old NUWA and I immediately registered in this forum. We are learning the rig now for a trip. I have not studied where someone has posted something similar, so here goes. The previous owner was, shall we say not as concerned about RV maintenance protocol, and did not have answers to many questions.
I was very glad to see the flush out for the black tank. I connected a hose to the flush out , opened valve to drain the black tank, turned the water on, and low and behold, no additional flushing water? What? Somehow the flushing water is not getting into the black tank. I'm new to this model but I have seen friends use the flush out before on their rigs without trouble. No where can I find a schematic of the water system. One look in the storage area trap door around the hot water tank one sees water lines going every where. The flush line disappears behind the Hot water tank out of site? Hmm, is there a shut off somewhere I am missing. I did notice shutoff valves I believe to by pass the hot water tank. Thanks for any help.
