Sure would make life easy! Last I checked they had made a device that floats in the fill tube and automatically refills reservoir when it gets low based off the pressure inside the empty reservoir or some shizznit but at the time the only way to run it was off of a water hose! That or you could prob make it work indoors off a reservoir if u had a fancy pump that could run 24/7 yet only pump water when the valve opened up to fill res! Prob make pumps like that but I’m not sure what kind they are!
Also thanks for the rep brotha! Add a vanilla pudding mix to a carrot cake mix and that biznatch comes out extra gooey!
