Pot filler faucets provide a convenient way to fill up stock pots and other large vessels. These can be installed on their own, near a prep line or as an extension of an existing fixture. Pot filler faucets come in two types. Those with flexible hoses can fill pots without the operator having to lift the vessel. The other comes in the form of nozzle extensions that let the faucet extend over the sink to reach pots.
