Faucets

We carry several faucets that will replace the standard equipment faucet on any reverse osmosis unit, regardless of brand. Below are our least expensive faucets, one in “air gap” style and one in non-air gap. Go here for our Full faucet list. This page shows a variety of faucets and explains and discusses installation, the drilling of holes, the concept of the air gap faucet, and other grippingly interesting topics.
