Consider using a branch fitting from the Valterra range, 2 inlets, 75mm and 32mm with a blade valve to control each size.
Then you can use the same hose to drain both without having to swap the drain hose from black to grey.

Drain the black then rinse with the grey before final rinse with fresh.

Good idea. The problem is my grey and black tanks are a few meters apart, if I used a 32mm outlet for the grey I might be able to fit plumbing in to run it forward to the Black outlet and use a branch fitting as you suggest. Where is a good source of these fittings?

Not sure, I looked at their Web site in the states, RV type stores or import your self from the States.
