If you work for a busy commercial kitchen, you know how many dishes, pots, and pans need to be washed daily. It’s enough for one or more to have a full-time job – just washing dishes and maintaining sanitation standards. One tool that can help the process go more smoothly is a pre-rinse faucet.

Pre-rinse faucets are designed to pre-rinse dishes and other cookware before it is placed into a commercial warewasher. It can also be used to pre-rinse items before they are washed and sanitized by hand.

Typically installed at a two or three-compartment sink, pre-rinse faucets come in two designs: splash or wall-mounted. Splash or deck mount options are when the unit is directly installed into the sink. Wall-mounted options are mounted into the wall or backsplash.

Deck- or wall-mounted pre-rinse faucets can be purchased with a gooseneck or as a roto-flex. As mentioned in What to Consider When Purchasing a Commercial Faucet, gooseneck nozzles are named such for the way they stand straight, then curve like an actual goose’s neck. The roto-flex pre-rinse faucets are constructed of rigid pipes and/or a flexible hose, making it possible to pivot the spraying unit in multiple directions.

When purchasing any of the units thus far described, buyers should consider their centers and gallons per minute capacities.

Pre-Rinse Faucet

When buyers browse faucets, they’ll see the terms “on center.” This phrase refers to the distance between each of the faucet inlets. They come 3”, 4”, 6”, and 8” apart. The most common configuration is an 8” distance between each faucet inlet. This “center” should match the distance between each handles’ water supply line. Because of this, buyers should examine what kind of setup their current sink already has and how many inches apart the water supply lines are, so it lines up with their chosen faucet.

This is true in every case except if the sink requires a deck-mounted faucet with a single hole. This makes the centers inconsequential because they must be connected with flex hoses.

Gallons per minute (GPM) designates how much water the faucet dispenses in a minute. Standard flow rates are 1 to 1-1/2 gallons every minute, however, low-flow options dispense about half this amount.

Low-flow units are ideal for the environmentally-conscious or those hoping to save on water costs. They work just as effectively in removing caked-on foods.

The flow rate is often controlled by spray valves, which are purchased separately as an attachment for pre-rinse faucets.


In addition to spray valves, operators can choose to add other accessories to their pre-rinse system. One such addition is a separate “add on” faucet. They are directly attached to the pre-rinse unit, but unlike its flexible style, it stands rigid and has a higher water flow rate to fill compartment sinks with water for cleaning and sanitizing dishes. The pre-rinse faucets are not designed to fill sinks so this can be a great addition for operations that need it.

Hold down rings can be purchased to cover spray valves handles, allowing operators to hold them open with minimal fatigue.

The type of handle can be changed. Most units come with lever handles, but many manufacturers will switch this out for wrist handles, club handles, and even foot pedal valves if requested.


For operations where pre-rinse faucet height is a concern, we recommend looking into T&S Brass’ mini models. These units are about half the height of a standard pre-rinse faucet but are just as powerful and effective.
