Customer Questions & Answers

Air gap is smaller then sink hole. Is there a rubber gasket that would fit uner the top section of the air gap?

When the dish washer drains, the water comes out of the air gap, and leaks down the sink hole. Is this normal?
Asked by: Miles
The sink hole being slightly larger is normal. The gasket that comes with the air gap is supposed to go on the top of the counter, under the "nut", not under the counter. The leaking is NOT normal. You may have flow that is restricted (ex. debris in your garbage disposal). When that happens, it backs up and dumps that dishwasher drain water onto your counter top and hopefully into your sink using the air slats. I had a problem with that and it was largely due to a kinked "turn" in my hose going from the air gap to the base of the garbage disposal unit. I replaced the kinked hose with a new pre-cut 2-foot section and it no longer is a problem. You can also check to see if your leaking is coming from the 2 hoses that connect to the air gap. They should have hose clamps on them. The hoses are not just pushed on.

Customer Reviews

Classic Collection Kitchen Air Gap in Venetian Bronze is rated 4.1 out of 5 by 10.
Rated 1 out of 5 by from Not Recommended. Spend the money for a air gap made completely out of metal. The materials used to manufacture this air gap are of such poor quality (very cheap plastic) that the threads of the nuts cannot hold onto the threads of the shaft when tightening by hand (the threads jump and cross thread themselves). It is not possible to tighten this fixture enough to create a leak proof seal and if you just nudge the air gap once installed with 4-5 lbs of pressure, the threads will pop out and cross mandating re-installation. I do not recommend this for any quality plumbing job/installation. Use only if you don't mind your dishwasher draining out underneath your sink.

Rated 5 out of 5 by from Updated version has flange and hides the white base! Delta makes an updated version of this with the same part number, which is what I received when I bought mine. Looks like the picture another reviewer posted of it installed. It has a bit of a flange at the bottom so you no longer see the white part at the base. You can still see the white "pipe" inside the little slats if you look at it just right. I suppose you could "Rit dye" the white plastic darker or spray paint it. I also bought a new pre-cut 2-foot section of hose to go with it while at the Depot plumbing aisle. Everything nice and clean and odor-free.

Rated 5 out of 5 by from Good match for new delta faucet I bought Easy to install, shipped quickly, met all expectations

Rated 5 out of 5 by from Perfect match for the Delta faucet! Easy to install, same finish as the faucet, and is more compact than the ugly chrome air gap it replaced with the old faucet.

Rated 4 out of 5 by from Brushed Bronze After shopping around for the right faucet, I decided upon a brushed bronze finish... little did I know how difficult it would be to find components that match the "right" brushed bronze finish. We bought a Delta faucet in Venetian Bronze & this Air gap matches beautifully!! So thrilled about the finish... my only qualm is the white rubber washer that stands out like a sore thumb on my granite counter with bronze fixtures... if only that were black it would have been perfect.

Rated 1 out of 5 by from not really venetion bronze in color Ordered venetion bronze to match our delta faucet purchased also at home is black, does not match the faucet set...and secondly, the cap does not fit over the plastic air gap assembly... frustrating!! also ordered a new copper sink that was to have included a matching basket strainer, stopper and disposer flange...none of these items came with the sink when it was delivered... Frustrating !! Very poor quality control !!

Rated 5 out of 5 by from It's an Air Gap - How much can you review? It's an air gap for a dishwasher. How exciting! It matches the other sink items.
