When I dump and Flush my Black tank I always make sure my 2 Grey tanks are Almost full as it Works AWESOME for Back flushing the Black tank ,after I make the initial Dump and flush of the Black I CLOSE my End termination valve and let the Grey tanks loose for about 30 seconds and it goes back up into the black tank then I open the end valve and you would not believe how much More comes out of the black tank after the regular Factory flushing ,it puts a Flush King to Shame and I have never had a tank Blow having my grey tanks full to do this

Great idea. Think I will give this a try. My black tank valve hasn't completely sealed since new so perhaps using this method plus my usual black tank flush will clean out whatever is preventing the valve from closing completely.
