Beverage Faucets

Beverage Faucet Products

Beverage faucets in this category are grouped by the water source they serve and how they connect under the sink. Use the groups below to match the faucet to the system.

Reverse Osmosis Faucets

Reverse osmosis faucets are built for the low-pressure output of an RO system, whether it uses a storage tank or a tankless unit. They connect to the product water line, typically 1/4 in. tubing, and dispense water that has passed through the membrane and post-filter.

Air Gap and Non-Air Gap Faucets

An air gap faucet includes a built-in air break that channels RO reject water to the drain and prevents wastewater from backing into the system. It adds a drain tube under the sink. Non-air gap models use a single supply line where local code does not require an air gap.

Filtered Water Faucets

Filtered water faucets and water filtration faucets connect to carbon block, sediment, or multi-stage under-sink filters that run at line pressure. Many are also compatible with RO systems, so the faucet can stay in place if the treatment system changes later.

Cold Water Dispenser Faucets

A cold water dispenser faucet connects to a water chiller or a cold filtered line. Most standard beverage models are rated for cold water only and cannot be connected to an instant hot tank. Check the product specifications before connecting any heated supply line.

Hot Water and Hot/Cold Dispenser Faucets

Hot water dispensers connect to an under-sink tank that heats water to near boiling for tea, instant foods, and cleanup. Hot/cold models add a second valve for filtered cold water. Look for insulated spouts and self-closing valves; tanks and filters are often sold separately.

How Beverage Faucets Work and Where to Use Them

Supply and Drain Connections

The faucet mounts through the deck and secures with a mounting nut from below. Its supply tube connects to the filter or RO outlet, commonly with a 3/8 in. compression fitting or a 1/4 in. quick-connect. Air gap models also route a drain tube to the sink tailpiece or a drain saddle.

Cold-Only vs Hot Operation

Cold-only valves are not built for heated water. Hot water dispensers use valves and spouts rated for near-boiling temperatures and connect only to their matching tank, so the two types are not interchangeable. Connecting a cold-only faucet to a hot tank can damage the valve seals.

Installation Locations

Kitchen beverage faucets and kitchen drinking water faucets are installed next to the main faucet, at a prep sink, in a wet bar, or in a pantry or butler's kitchen. See Kitchen & Bar Sinks for compatible sinks and bowl configurations. Each location needs cabinet space for the filter or tank.

Key Specifications and Planning Steps

Mounting and Hole Size

Most beverage faucets are single-hole, deck-mounted units. Confirm the hole diameter and maximum deck thickness on the spec sheet, as limits vary by model; some accept decks up to 3 in. thick. Place the hole so the spout reaches the bowl and clears the main faucet and sprayer.

Connections and Flow Rate

Confirm tubing size, fitting type, and whether supply tubes are integrated. Flow rates are lower than a standard kitchen faucet; many models are rated at 1.5 gpm at 60 psi. Use Supply Lines where adapters are needed.

Compliance

Faucets that dispense drinking water must meet federal lead-free requirements. Look for NSF/ANSI 61 and NSF/ANSI 372 certification, and check local code for air gap and ADA requirements. Under the Safe Drinking Water Act, wetted surfaces must average no more than 0.25% lead.

Choosing the Right Beverage Faucet

Start with the treatment system. Drinking water faucets for RO units should match the system's tubing size and air gap requirement, while line-pressure filters work with most filtered models. Next, decide on temperature: a cold-only faucet for filtered or chilled water, or a dedicated hot or hot/cold dispenser with its tank. Then confirm deck thickness, the available hole, and spout reach. Match the finish and handle to the main faucet so beverage faucets for kitchen sinks read as one set. A dedicated faucet keeps the filter under the sink and leaves the main faucet unchanged, unlike a faucet-mounted filter. For cartridges and fittings, see Water Filter Accessories.

Frequently Asked Questions

Where can I buy beverage faucets for a reverse osmosis system install in the US?

Beverage faucets rated for reverse osmosis use are listed in this category, including air gap and non-air gap models. Before ordering, confirm the faucet matches the RO system's tubing size and whether local code requires an air gap.

Which filtered water faucets match the finish of the main kitchen faucet?

Most filtered water faucets are offered in common finishes such as chrome, stainless, matte black, polished nickel, and bronze tones. Select the same finish and a similar handle style as the main faucet so both fixtures read as one set.

What is the difference between a beverage faucet and a bar faucet?

A bar faucet is a compact kitchen faucet that runs hot and cold tap water at a secondary sink. A beverage faucet dispenses only treated water from an RO system, filter, chiller, or hot tank, and usually sits beside a main faucet.

Should I install an air gap faucet or a non-air gap faucet on an RO system?

Install an air gap faucet where local plumbing code requires an air break on the RO drain line. Non-air gap faucets have a single supply connection and work where the RO system uses its own approved drain connection.

Should I choose a cold water dispenser faucet or a hot and cold model?

A cold water dispenser faucet suits filtered or chilled drinking water. Choose a hot/cold dispenser when the job also calls for near-boiling water; it requires a matching under-sink hot tank.

Can a beverage faucet connect to an instant hot water tank?

Most standard beverage faucets are rated for cold water only and should not connect to an instant hot tank. Hot water requires a dispenser rated for heated water and designed for its matching tank.

How do I connect the drain line on an air gap faucet?

Connect the RO reject line to the faucet's air gap inlet, then route the larger drain tube from the air gap outlet to a drain saddle on the sink tailpiece above the P-trap. Keep the drain tube free of dips and kinks.

What deck thickness can a single-hole beverage faucet mount through?

Limits vary by model. Many single-hole faucets fit standard sink decks and countertops, and some accept decks up to 3 in. thick. Check the maximum deck thickness and hole diameter on the spec sheet.

What tubing and fittings do water filtration faucets use?

Water filtration faucets commonly connect with 1/4 in. tubing or a 3/8 in. compression fitting, depending on the model. Air gap models add a drain tube, and adapters join mismatched sizes.

Where should I drill the hole for a filtered water faucet?

Drill on the sink deck or countertop beside the main faucet, where the spout reaches the bowl and clears the main faucet and sprayer. Check under-deck clearance and use a hole saw rated for the countertop material.

What are beverage faucets used for besides drinking water?

They supply treated water for cooking, coffee and tea makers, ice trays, pet bowls, and filling bottles. Hot water models also serve instant foods and cleanup tasks.

Do reverse osmosis faucets need to be lead-free and NSF certified?

Yes. Reverse osmosis faucets that dispense drinking water must meet the federal lead-free limit of 0.25% weighted average lead on wetted surfaces. NSF/ANSI 61 and 372 certification is the common way to confirm compliance.

Can kitchen drinking water faucets go in a pantry or wet bar?

Yes. Kitchen drinking water faucets are installed at a wet bar, prep sink, pantry, or butler's kitchen, provided the location has a sink, drain access, and cabinet space for the filter or tank.

What flow rate do beverage faucets for kitchen sinks deliver?

Beverage faucets for kitchen sinks flow at lower rates than a main kitchen faucet. Many models are rated at 1.5 gpm at 60 psi, and RO output can be lower depending on system pressure.

 Is a filtered drinking water dispenser faucet better than a faucet-mounted filter?

A filtered drinking water dispenser faucet keeps the filter under the sink, leaves the main faucet's flow and sprayer unchanged, and supports higher-capacity systems such as RO. A faucet-mounted filter needs no extra hole but adds bulk at the spout.
