I wouldn&rsquo;t like to open my dishwasher to find my clean plates sitting in grey and brown drain water!<\/p>\n\n\n\n<p>This air gap has a head that protrudes up by your sink. It has a hole for air and will also expel built-up water instead of letting it go through your dishwasher.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>For more information, you can check out <a href=\"https:\/\/thetibble.com\/dishwasher-air-gap-what-why\/\" data-type=\"post\" data-id=\"20923\">Dishwasher Air Gap: What It Is and Why Is It Used?<\/a><\/p><\/blockquote><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Dishwasher Air Gap Requirements<\/h2>\n\n\n\n<p>There are requirements for what air gap you can use. These devices must be listed and approved by the International Code Council (ICC).<\/p>\n\n\n\n<p>A <strong>listed<\/strong> item has been assigned a listing code that comes from an ICC-approved organization that tests and regulates safety and performance. The International Residential Code (IRC), per <a href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-27-plumbing-fixtures#IRC2021P1_Pt07_Ch27_SecP2717.1\" target=\"_blank\" rel=\"noreferrer noopener\">Section P2717.1<\/a>, requires an air gap to have an ASME A112.1.3\/A112.1.2 listing.<\/p>\n\n\n\n<p>An air gap must comply with ASME A112.1.2, while a fitting version must have an ASME A112.1.3 listing (<a href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-29-water-supply-and-distribution#IRC2021P1_Pt07_Ch29_SecP2902.3.1\" target=\"_blank\" rel=\"noreferrer noopener\">Section P2902.3.1<\/a>).<\/p>\n\n\n\n<p>ASME is the American Society of Mechanical Engineers. When a product is ASME accredited, this means that it complies with regulations in the codes and attests to the quality and safety of the product.<\/p>\n\n\n\n<p>To say that your air gap must be <strong>approved<\/strong> means that the IRC agrees with the testing and standards of the organization (for which it provides a rating), and that by using an appropriately listed item, you are complying with code regulations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Code Installation Requirements<\/h2>\n\n\n\n<p>The IRC, <a rel=\"noreferrer noopener\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-29-water-supply-and-distribution#IRC2021P1_Pt07_Ch29_SecP2902.3.1\" target=\"_blank\">Section P2902.3.1<\/a>, measures air gaps vertically between the lowest part of the water outlet and the flood level rim. This dimension must be double the diameter of the effective opening.<\/p>\n\n\n\n<p>If you look at the California code quoted earlier in the article, you can see that an air gap must be installed on par with or above the sink or draining board level. This relates to the flood level.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed.jpg\" alt=\"Stainless steel faucet with dishwasher air gap installed\" class=\"wp-image-22290\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-735x536.jpg 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-335x244.jpg 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-347x253.jpg 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-520x379.jpg 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-640x467.jpg 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-960x700.jpg 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed.jpg.webp\" alt=\"Stainless steel faucet with dishwasher air gap installed\" class=\"wp-image-22290 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-735x536.jpg.webp 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-335x244.jpg.webp 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-347x253.jpg.webp 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-520x379.jpg.webp 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-640x467.jpg.webp 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed-960x700.jpg.webp 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Stainless-steel-faucet-with-dishwasher-air-gap-installed.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>An air gap has a literal opening in it to add air into the system and prevent pressure from building in the tube. You need to install this at or above the sink line or drainage board in order to prevent any backed-up water from overflowing into your cabinets, damaging them and your flooring.<\/p>\n\n\n\n<p>By installing the air gap above the dishwasher, you keep siphoning from occurring and allow any overflowing drain water to eject into the sink where it can drain away.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do All Dishwashers Require Air Gaps?<\/h2>\n\n\n\n<p>All dishwashers, even new ones, are required by law in California to have an air gap. <\/p>\n\n\n\n<p>Other methods (high loop and standpipe) serve a similar function to an air gap. Still, the air gap fitting is the most reliable way to protect your water supply and is, therefore, adopted as the regulated method in many states.<\/p>\n\n\n\n<p>Most dishwashers do not have an in-built air gap (only a check valve), so you will likely need to purchase and install the device. This is probably because not all states require them. Even the IRC does not specify their inclusion in the dishwasher drainage system. California has added this regulation.<\/p>\n\n\n\n<p>You might come across sources that tell you it is possible to bypass the air gap requirement by performing the installation yourself or even by removing the air gap after inspections are complete. <\/p>\n\n\n\n<p>But this would compromise your insurance and warranty claims, and the latter would render your claims fraudulent.<\/p>\n\n\n\n<p>Even if your state doesn&rsquo;t require an air gap to prevent backflow, I still recommend an air gap over alternatives. <\/p>\n\n\n\n<p>It is the most highly-rated way to prevent sewage water from entering your dishwasher and flooding out of clogged drainpipes since there are no moving parts that can break and cause the device to fail. <\/p>\n\n\n\n<p>There are also many aesthetic ways to incorporate the air gap into your kitchen, which makes the protrusion a worthwhile feature to deal with.<\/p>\n\n\n<div class=\"lazyblock-amazonblock-Z14uQL1
