I very rarely write negative reviews, but this product deserves one. I replaced my old air gap reverse osmosis faucet with this one. It looked very similar so I was hoping it would perform as well as the worn one it replaced. It's not like this. The air gap leaked like crazy both at the side vent and around the grip. I've never had a water leak from the old one, so I know it wasn't my drain line. I ended up cutting the drain lines off of this and used a separate air gap unit under the sink instead (https://www.amazon.com/dp/B01ENLX7F6).
