I am looking to fill and flush our Grey tanks using Unique Tank Cleaner. What do you recommend as the best method for filling the Grey tanks for this maintenance?

For my 2970RL, the only way I know to do it is run water down the kitchen sink drain for the rear tank and the shower drain for the front tank.
