Connect to Garbage Disposal — Disconnect Drain Hose Under Sink
Part of project
How to Clean or Replace a Dishwasher Air Gap · Step 3 of 8
In this video
Connect the drain line to the garbage disposal. First, use a screwdriver to ensure the knockout plug inside the disposal's dishwasher inlet is completely removed. Next, trim the 7/8' hose to the appropriate length using a pipe cutter, making sure it will have a continuous downward slope from the air gap. Attach the hose to the disposal inlet and secure it with a stainless steel hose clamp, tightening it with a power drill.
Goal: Attach the air gap's drain hose to the garbage disposal.
- Failure to remove the knockout plug from the garbage disposal inlet will cause the dishwasher to not drain.
- The hose must run downhill from the air gap to the disposal to prevent standing water.

FAQs
Why is my dishwasher air gap sputtering water onto the counter?
This is the most common symptom of a clogged air gap. Debris like food particles or grease from your dishwasher accumulates inside, preventing proper drainage and forcing water out. Cleaning the air gap thoroughly, especially the internal components and hoses, should resolve the issue.
What are the essential tools I'll need for this project, especially if I'm just cleaning the air gap?
For cleaning, you'll primarily need a pair of tongue-and-groove pliers to loosen the nuts, a screwdriver for hose clamps, and a flashlight for inspection. Don't forget old towels or a bucket to catch water. If replacing, these same tools will be used, along with the new air gap unit.
How long will this project realistically take a beginner, and what's the estimated cost?
For a beginner, cleaning the air gap typically takes 30-60 minutes, while a replacement might take 1-2 hours. The estimated 3 hours allows ample time for troubleshooting and cleanup. The cost for cleaning is zero, and a new air gap usually ranges from $30-$50, making it a very affordable fix.
Are there any crucial safety precautions or warnings I should be aware of before starting this project?
Always place a bucket and plenty of old towels under the sink to catch any spilled water, as disconnecting hoses will inevitably cause some leakage. Wearing heavy-duty latex gloves will protect your hands from grime and potential sharp edges. If you're disconnecting any electrical components related to the dishwasher, turn off the power at the circuit breaker first.
