Putting another shut off valve at the end of the discharge line and leaving it open won't work when dry camping as you have to deal with all that gray water when you want to dump the black. I still have to look how long of a run it is from the galley tank to the convenience centre and if it is less than 72" I should be able to purchase a replacement cable and move it. Does anyone know the distance by any chance?
I like Joe's solution of the 48" sprinkler key.
