A:Â Hi Potential buyer! This is a bottom loading water cooler that uses a pump to pull water out of the bottle. There is no way to bypass the bottle to connect the cooler to a water line. If you would like a water cooler that connects to a water line, the A5bottleless is identical to the A3 and will connect to a water line. Our customer success team would be happy to provide you with more information and answer any questions that you may have. Please contact us at 1800-256-0695 to by email at support@avalonh2o.com. Happy Hydrating!
