Some of the Alpines have the washer plumbed into the galley tank... I have a 2014 Alpine and that’s how mine is plumbed.. So if you are using the clothes washer then yes your galley tank will fill faster..

I would also not ever leave my gray tank dump valves open when hooked to RV Park sewer.. open them once every other day and then close.. if left open you are inviting sewer aroma and other things to come up that hose into your RV.
