Drinking Water Faucets

This page carries dedicated drinking-water faucets for reverse osmosis systems and under-sink filter systems. You can choose from two Tier1 styles, the LF-EC25-CP ceramic faucet in chrome and the LF-BLR-BN long-reach faucet in brushed nickel, or the Culligan FCT-1 in chrome.

Common questions

Do you need a special faucet for reverse osmosis?

A reverse osmosis system uses a dedicated drinking-water faucet, because the RO system sends filtered water to its own tap rather than to your main kitchen faucet. Check your RO system's instructions for the faucet connection it requires.

Are RO faucets universal?

RO faucets are not guaranteed to fit every system. Check the connection size and installation requirements in your system's manual and on the faucet's product page before ordering.

Air gap vs non-air-gap: what's the difference?

An air-gap faucet includes a gap in the drain line that helps prevent drain water from flowing back into an RO system, while a non-air-gap faucet does not. Some local plumbing codes require an air gap. For replacement cartridges, see our under sink filter replacements.
