Pre-rinse units can greatly decrease the time employees spend scrapping dishes prior to placing them into a commercial dishwasher. Unlike residential models, commercial dishwashers are designed for light cleaning and sanitizing rather than cleaning heavily-soiled dishes. Pre-rinse faucets greatly aid in removing stuck-on food particles from dishes by utilizing a high-pressure pre-rinse spray valve that can blast the remnants free of the dish in a matter of seconds.
Like commercial kitchen faucets, pre-rinse units may be wall- or deck-mounted. Deck-mounted pre-rinse units are ideal when your water inlets come from the floor and enter your commercial sink or dishtable vertically. Wall-mounted pre-rinse faucets are used when the faucet assembly attaches to a sink’s backsplash or when the water inlets run through or against the wall.
Most pre-rinse units feature a riser, wall bracket, flexible metal hose and a spring attachment to position the pre-rinse spray valve above a commercial sink or dishtable for optimal results. This is especially important when scrapping large commercial cookware items such as stock pots, which often have food remnants stuck to the bottom and sides of the pot.
It is important that your pre-rinse unit is set at a height that makes cleaning such vessels easy for your kitchen employees. If the pre-rinse faucet is set too high, it may be difficult to position the pre-rinse spray head in a fashion that allows for easy cleaning while a pre-rinse unit that is set too low will often get in the way of the dishes it is supposed to scrap.
