Rated 5 out of 5 by Kandy from Good color choices Liked that this came in a matte black color. If your plumber insists on a doshwasher vent its nice to find one that goes with your decor.

Rated 4 out of 5 by Genol from Coordinated with New Faucet I had chrome and replaced with this to match new faucet. Not a perfect match but very close. I had to replace the previous base with the one Delta provided. A very simple task, taking less than 10mins.

Rated 1 out of 5 by Barb1964 from water all over counter I bought the air gap and cover to replace one that the builder had literally left under the sink. I have run the dishwasher 2x's and each time, water bubbles out of the air gap onto my counters.... The plumbers were out today to make sure that no lines were clogged: they weren't. They disconnected and reconnected the lines: tested it again....water all over the counters. There is a flaw in the design of the plastic air gap...have to go to a plumbing store to get a new plastic air gap... (The cover is fine..so far.)

Rated 1 out of 5 by Kater from Amazon sends unbranded boxes The only place I could find to buy the "SS" color to match the faucet finish we want was amazon. Ordered 2 (we're getting 2 dishwashers!), and received two boxes from them, neither identifies as being a "Delta" product as the description indicated. Not sure where else to find them as none of the authorized dealers carry this finish. Can't order them from here because Delta doesn't personally sell their own products. Disappointed my faucet I was so excited to get back (I had a Touch2O at my last house that I sold) might have to go back for a brand that offers matching code required accessories :(

Rated 5 out of 5 by Homework from Quality Air Gap This is a quality air gap from Delta. It's much better than the cheap ones you'd buy at the home improvement stores. The Delta air gap has thicker metal and better looking chrome than the others. The trick to installing this is to set the plastic mounting assembly at the correct height- if it's set too high then the chrome cap won't cover it entirely. When you've got it set just right the chrome cap comes all the way down to sit right on the sink surface.

Can I purchase just the CAP for the air gap 72020-rb ?
Thank you for your question, Doug! The Delta air gap is sold as one piece and there are no separate parts available currently. Best regards, Edward

Does the 72020-rb work with the 19949-dst. We would need Venetian bronze.
Hi, Thank you for your question. The Delta 72020-RB can be used in addition to the Delta 19949-RB-DST kitchen faucet. Best regards, Brandis

What does an air gap do and when is it needed?
Hi xhotcapp, Thank you for your question. The model 72020 Air Gap is installed to prevent backflow or back siphonage of non potable water into potable water systems. It is most often installed for use with dishwashers. The air gap prevents the dirty water leaving the dishwasher from getting back into the dishwasher. You may need to check your local building codes to see if one is required in your area. Thanks, Dave

What exactly is the kitchen air gap, what is it used for and how and where is it installed. Is it something that helps with the water pressure?
Hello Doowop47, Thank you for your question regarding the Delta Kitchen Air Gap and I am happy to help you today. An air gap is installed to prevent backflow or backsiphonage of non potable water into potable water systems. It is most often installed for use with dishwashers. The air gap prevents the dirty water leaving the dishwasher from getting back into the dishwasher and are typically installed on the counter nearest to the dishwasher. To install the air gap, you will need to connect the larger leg below the counter to a garbage disposal or sink trap and the smaller leg to the hose from the dishwasher. Only the cover and a few inches of the body will be visible from above the counter as the collar gasket and nut will hold the air gap in place. Please do not hesitate to give us a call on our warranty line at 800-345-3358 if we can assist you with anything going forward. Thank you, Brandy

Why is the bottom ring around the air gap WHITE?
I have customers complain that the rim around where the cap fits down over the air gap is WHITE and stands out! It looks tacky.
Thank you for your concern. Delta Faucet model # 72020-RB has a ring around the bottom to keep the finish from coming in contact with water. Our R & D department has been looking at a better design for the Venetian Bronze finish but at this point, it is the only way this product is available.

What does this do?
Thank you for your question, Gordon! An air gap is used to prevent backflow or back siphonage of non potable water into potable water systems. It is typically installed for use with dishwashers but is sometimes used with reverse osmosis filtration systems if required by state or local codes. Best regards, Edward

In one picture, it shows a flange bottom. In another it shows no flange and a white washer at the bottom. Which one is accurate for bronze finish?
Hi Amy, Thank you for your question. The current verson of 72020-RB will have the finished venetian bronze flange at the bottom of the air gap cap. Thanks, Dave
