Product Overview

The Design House Dishwasher Air Gap, constructed from durable brass and ABS materials, is designed to ensure that water flows only in the right direction during the dishwasher cycle. The air gap also helps to prevent standing water in the dishwasher tub in the event of a drain hose clog. Should a dishwasher drain hose become clogged with food matter, a dishwasher will still have the ability to pump out the waste water from within the wash tub. Will help prevent any contaminated water from entering dishwasher and contaminating dishes or possibly leaking from the wash cycle into a home.

  • Helps to prevent waste water from dishwasher from backing up into dishwasher
  • Durable brass cap and ABS body construction
  • 1-3/4 in. diameter and 2-1/4 in. brass cap
  • 5/8 in. inlet and 7/8 in. outlet
  • Can accommodate up to 1-1/4 in. deck thickness
  • Hose connections not included
  • Meets IAPMO standards: UPC and cUPC compliant
  • 1 year limited warranty

Customer Questions & Answers

Is a dishwasher Air gap needed for all installations

I've notice not all kitchen sink faucets have one
Asked by: Clint
In the state of California it is required but I do not know in your state.

How does this hold up with hard water deposits..... can you wipe it clean or am I going to have a problem with the hard water.

Asked by: bunnywoman
Mine was just installed so I don't know yet but it might be a good idea to always wipe it off to prevent build up. Wrapping faucet fixtures in a towel soaked in white vinegar eats any hard water build up but I am not sure if it will damage oil rubbed bronze. It works on chrome with no problem.

The Cap on the Top

I bought a white air gap top and need the oil rubbed one, which was not in my local store. If I order this one online and it takes a while for delivery, can I use the white air gap body when my sink is installed prior to receiving the oil rubbed bronze one and just replace the top once the right one is received?
Asked by: SashasMum
The cap does pull off on the one I have. I am not sure if the insides is a universal size so you might want to call a plumber just in case.

We purchased this Air Gap product to match our new bronze colored Delta kitchen faucet. They match perfectly. I am happy with the quality. Easy to install with just 2 hose clamps and the air gap is hand-tightened with the nut onto the sink. The hose sizes were an exact match to our previous air gap connections.

Rated 5 out of 5 by from Great value I ordered 3 different bronze air gaps to see wich one matched our new Moen faucet in Mediterranean Bronze the best. This and one other matched great... but at $10 less than the other, I'm keeping this one.
