On my 5th wheel I have 2 black tank flushes. I am wanting to plumb them together into a Wye Connector. My thoughts are that I can hook up the hose one time and then just turn on the valve going to whichever tank I want to flush.
Has anyone done this and if so what did you use. I was thinking about just using pieces of a garden hose connected to a Metal Wye connecter.
