Understanding the Dishwasher Air Gap
What Is a Dishwasher Air Gap?
A dishwasher air gap is a small device that helps ensure dirty water does not siphon back into the dishwasher from the sink or garbage disposal.
It is usually located on the countertop or sink deck and is often metallic or plastic in appearance.
Preventing Backflow and Contamination
The air gap’s critical role is to prevent backflow. This is important because it keeps contaminated water from re-entering your dishwasher, which could lead to health hazards if dirty water mixes with clean dishes.
Locating the Air Gap in Your Kitchen
To find the air gap, look for a small, cylindrical fixture next to your kitchen faucet. It often has a couple of small hoses attached to it under the sink.
Preparing to Remove the Dishwasher Air Gap
Gathering Your Tools and Materials
Before starting the removal, you’ll need a few tools: a wrench or pliers, a towel or bucket, and a screwdriver, if applicable. Ensure you have these items on hand to proceed efficiently.
Shutting Off Water and Power
Safety first. Always shut off the water supply to your dishwasher and turn off the power at the circuit breaker before beginning any work.
Clearing the Work Area
Remove any items from under the sink and around the dishwasher to create space. This will give you clear access to the air gap and related plumbing.
Draining Water from the Air Gap
Place a towel or a bucket beneath the air gap to catch any water. Then, drain water from the air gap or the connected hoses to prevent spills.
Step-by-Step Removal Process
Detaching Hoses from the Air Gap
Use pliers to loosen the hose clamps and detach the hoses from the nipples on the air gap. Be gentle to avoid damage to the hoses or clamps.
Removing the Mounting Nut
Under the sink, locate the mounting nut that holds the air gap in place. Use a wrench to loosen and remove this nut carefully.
Lifting Out the Air Gap
Once the mounting nut is removed, you can lift the air gap device out from the top of the sink or countertop. It should come out with little resistance.
Cleaning the Installation Area
With the air gap removed, clean any residue or buildup from the area where it was installed. This ensures a clean surface for any future use or installation.
Sealing or Replacing the Air Gap
Consider sealing the hole with a stainless steel cap or replacing the air gap with a new device. Ensure it is perfectly fitted to avoid leaks or future issues.
Should you need a new fixture, such as a ceiling box, be sure to measure the opening accurately.
If you’re sealing the hole, pick a cap that matches your kitchen’s aesthetics. For those looking to understand other sizes, like the right toilet flange bolts, always ensure to get accurate measurements for a perfect fit.
