Water Dispensers
mains water connection
Term from the vending glossary
Direct connection of a vending machine or dispenser to the mains drinking water supply (cold line). Eliminates manual refilling of water tanks; required for point-of-use water dispensers and recommended for high-throughput automatic coffee machines.
A mains water connection permanently links a coffee machine or water dispenser to the potable water line. The refill tank is eliminated — along with it, the most common reason a machine stops mid-day.
Three elements are required for installation: an accessible tap point near the machine, a drain or collection tray for rinse water, and a check valve to prevent backflow from the machine into the building water line. Where these prerequisites are absent, tank operation is not the inferior solution but the only permissible one.
