Product review (4 stars): Fixed my air gap issue!
Had the classic leak at the air gap with a crack in the brass fittings running up into the faucet base into the Air Gap. This replacement helped with that issue (cracked air gap).

On a side note, if you are looking at this you likely had a leak at the air gap (this part has the air gap). I recommend everyone check their Reverse Osmosis draining tube often, especially if you have a disposal in your sink. If your sink backs up into the secondary sink, it is possible that the food which your disposal is bringing up could/can clog your black RO drainage tube. This also causes leaks at the air gap and usually is the main reason you have a counter full of water!
