Sani flush valve 2007 Nash 22GQ

Question

I have a 2007 Nash 22GQ travel trailer that has a valve next to the fresh water valve on the outside of the trailer and labeled Sani-flush. I know that this will flush out the system, but will it flush out both black and grey water tanks? And is all you do is hook up a hose, with a water pressure regulator, and open the black tank valve first, flush that out, then close it, then open the grey water take, same as black water tank? Should I perform this flushing every time I dump out my tanks at a dump station if there is not a long line?

Thanks!

Dave

It will only flush the black tank.

NO Grey tank unless there is a 'separate' flush connection
OEM Flush System...black tank

YES.....black tank dump valve should be open when 'flushing'
IF YOU close dump valve....do NOT walk away/get distracted cause black tank will fill up/overfill come up out of toilet and/or possibly blow out roof top vent.
