You should be able to unscrew it here, and then hook it to a hose with a properly sized adapter fitting to hook onto whatever hose you have.On another note, how can I hook a hose or something up to this sink to fill the tank about 15 feet away? Tanks near bar in basement and this would make it SUPER easy to do water changes. View attachment 1540872View attachment 1540873View attachment 1540872View attachment 1540873
