i don't like filling the water tanks as today and previously I have forgot the filling process and its overflowed into the below sink area.

Nothing worse than dragging a hose down inside the galley sink And waiting for 900 litres to fill into the bilge tanks!

Lucky I could open the other tank to drain the 20 litres of water and my electric steamer was submerged! See how that goes next time I want corn cobs!
