We double-duty the draining of the fresh water. After dumping black then gray water, we then turn-on all the faucets/shower and let the fresh water run through the gray tank and out the drain hose ... does as good a job of 'rinsing' the tubing as the alternative - using water straight out of the hose. Remember, we're in California where the drought is serious and we get fined for exceeding stringent water allotments.
