Our grey water goes into the black water tank. When I drain the black water, I close the handle and open the grey water and it helps clean out the black water hose. ajjoez

Your bathroom sink drain should be plumbed to your grey tank not your black so that shouldn't be your problem. It could be that your vent to your black tank is plugged or, if your rig is prepped for a washer/dryer and you don't have one, the problem could be coming from the open drain line for the washer.
