What is a Reverse Osmosis (RO) Faucet?

A reverse osmosis (RO) faucet is a specialized tap, designed to dispense water that has been filtered through a reverse osmosis system. The structure of a reverse osmosis faucet includes: a base installed into a countertop hole, an activation lever or dial, and a slender, curved spout for water dispensation. It's commonly installed adjacent to your standard sink tap and is a great investment if you’re looking to reduce contaminants in your water.

    How Do Reverse Osmosis Faucets Work?

    Your reverse osmosis faucet links to a water line directly connected to your water filter or a storage tank for filtered water, rather than to the unfiltered plumbing system. By engaging its integrated lever or dial, its internal valve activates, releasing the filtered water.

    Since these faucets are tailored to correspond with the output of their linked water filters, they usually have consistent water flow rates.

    RO Faucet Installations

    Generally, RO systems are positioned in kitchens, facilitating access to purified water for cooking or drinking. Here's what you need to know about RO faucet installations:

    • Placement of Faucet: If there's a pre-existing hole in your sink from a soap dispenser, sprayer, or any unused covered opening, it can be a convenient spot for the RO faucet.
    • Drilling a Hole: Otherwise, if your sink doesn't have these options or if it's custom-designed, you'll need to drill an appropriately sized hole in the sink or countertop to accommodate the faucet.
    • Water Line, Tubing & Components: To complete the installation, the faucet should be connected to the filtration system using a water line. A comprehensive system usually comes with all the required tubing and components.

    Reverse Osmosis Faucet FAQs

    What type of faucet for reverse osmosis?

    You will need a specialized faucet that’s designed to dispense the purified water. These faucets are tailored to be compatible with RO systems and are usually positioned adjacent to your standard sink tap. This configuration allows users to easily differentiate between purified water from the RO faucet and regular, non-filtered water from the standard faucet.

    Why do reverse osmosis faucets need an air gap?

    How many faucets can I connect to reverse osmosis?

    The number of reverse osmosis faucets you can connect largely depends on the output capacity of your RO system and the water pressure it can maintain. Generally, for a standard home RO system, it's most common to connect one dedicated faucet in the kitchen. However, with larger, more robust systems or with the use of additional booster pumps and storage tanks, it's possible to service multiple faucets or even integrate the system into your home's main water supply.
