It would add a little plumbing but I wish I had put in a T with a valve and hose fitting so I could more easily use a cleaning wand on the black tank. About once a month or so I pull a hose thru the trailer hooked up to a wand and give the black tank a good work over. the wand has a spinning pressure head, far better than the factory wash out line I would think....
