Best Air gap by far
This is the best air gap I have seen. The cover is actual metal!!! This Delta is a gem. The last Kohler I had was a metal paint coat on a plastic cover. This is the solid real deal.

Misleading
It must be installed underneath sink. You can not just place it a too old one

Better instructions needed.
Needs clearer instructions so a homeowner can install without issues. Other than that it works great.

Q&A
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.

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,

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
