I made the modification to flush with grey water and it works GREAT! But I didn't do it quite as planned. The DW and I went to the RV show and you know what can happen when you do. So I negotiated with the dealer to upgrade the new 5er with the mods I had on the old 5er and to also add the grey water flush system. He did a great job and also decided to make the same mod to his personal 5er.
We just came back from a 6-day camping trip where we started flushing with grey water on day 2. There was no smell, the bowl continued to look as good as a bowl can look, and my tanks balanced out very nicely.
I have two grey tanks and only use the bath water.The tank was tapped low to avoid scum and hair and a screen filter was added just before the pump.
I add my black tank chemicals to the grey tank and they are "automatically" dispensed in the black tank as needed, although I did give the black tank an initial dose.
I tested the system, trying in all the known ways to pump grey water back into the fresh water system. The check valves and tee valve did their jobs.
