Question: How do you get the water to flow through the water pipes without any gravity present?

Answer: The shuttle water tanks are pressurized with nitrogen, and this helps force water flow. In addition, the tanks contain metal "bellows," which act with a spring force to push water out of the tanks. The galley, which supplies drinking water to the crew, works by using pumps to deliver water.
