no it does not. just put a loop in the drain line before it goes into the disposal drain.
Sorry, there was a problem. Please try again later.The drain hose for the LG 24" Front Control Built-In Stainless Steel Tub Dishwasher with 3rd Rack, Quadwash™, and 48dba - PrintProof™ Stainless Steel, Model # LDFN4542S, can be connected to a Disposal or Waste Tee with or without an Air Gap. Air gaps are generally required for dishwashers in many states across the United States to prevent contamination of the drinking water supply. In the United States, many states have adopted plumbing codes that require a dishwasher air gap to prevent potential contamination of the drinking water supply. While many states have strict regulations regarding dishwasher air gaps, there are others where these devices are not mandatory. In these states, local building codes may offer alternatives, such as high-loop installations, which serve a similar purpose but may not be as effective. It’s essential for homeowners to check their local building codes or consult with a licensed plumber to understand the specific regulations in their area. Even if your state does not mandate an air gap, installing one is considered good practice for safeguarding against cross-contamination and ensuring proper drainage of your dishwasher...^Ivan
