Hello again folks. When I picked up my 2017 Premier a couple weeks ago, the dealer explained the procedure to flush the black water tank on my 19FBPR Premier. But honestly I was suffering from overload with all the info the dealer was flooding me with.
I do recall something about when I hook up the water hose to the flush port on back exterior wall of TT, to open "something" up so as not to blow out/damage the plumbing, and create a heck of a mess.
Hopefully someone can help me out with the details of this procedure.
Many thanks,
Mike
