Installing a dishwasher air gap is a crucial step in maintaining a functional and efficient dishwasher system. An air gap is a device that prevents backflow of water from the dishwasher into the sink drain, minimizing the risk of contamination and ensuring proper drainage. In this comprehensive guide, we will walk you through the steps on how to install a dishwasher air gap, providing detailed instructions and helpful tips to ensure a successful installation.
Understanding the Dishwasher Air Gap
The dishwasher air gap is a small, cylindrical device typically made of plastic or metal that is installed on the sink countertop. It has two openings: one connects to the dishwasher drain hose, and the other is open to the air. When the dishwasher drains, water flows through the hose into the air gap and then falls into the sink drain through a small gap between the hose and the air gap’s opening. This gap prevents water from flowing back into the dishwasher if there is a blockage in the drain.
Materials and Tools Required
Before you begin the installation, gather the necessary materials and tools:
- Dishwasher air gap
- Plumber’s putty
- Adjustable wrench
- Screwdriver
- Utility knife
- Measuring tape
- Pencil
Step-by-Step Installation Guide
1. Choose the Installation Location:
- Determine the location where the dishwasher air gap will be installed on the countertop.
- Ensure the location is close to the dishwasher and sink drain.
2. Mark the Hole:
- Using a measuring tape and pencil, mark the center of the chosen location on the countertop.
- The hole should be approximately 1-1/2 inches in diameter.
3. Cut the Hole:
- Use a utility knife to carefully cut a hole in the countertop at the marked location.
- Smooth the edges of the hole using sandpaper or a file.
4. Apply Plumber’s Putty:
- Roll a small amount of plumber’s putty into a rope.
- Apply the putty around the base of the dishwasher air gap.
5. Insert the Air Gap:
- Insert the air gap into the hole in the countertop.
- Press firmly to ensure the putty forms a seal.
6. Secure the Air Gap:
- Tighten the locknut on the underside of the countertop with an adjustable wrench.
- Do not overtighten as this could damage the countertop.
7. Connect the Dishwasher Hose:
- Attach the dishwasher drain hose to the inlet of the air gap.
- Secure the connection with a hose clamp.
8. Connect to the Sink Drain:
- Insert the other end of the dishwasher hose into the sink drain.
- Secure the connection with a hose clamp.
Troubleshooting Tips
- If water is leaking from the air gap, check if the putty seal is properly formed and if the locknut is tightened securely.
- If water is not draining properly, ensure that the drain hose is not kinked or blocked.
- If the air gap is making a gurgling noise, it may be clogged with debris. Remove the air gap and clean it thoroughly.
Safety Precautions
- Always turn off the water supply before starting the installation.
- Wear safety glasses when using a utility knife.
- If you are not comfortable performing the installation yourself, contact a qualified plumber.
Finishing Touches
Once the air gap is installed, wipe it clean with a damp cloth. You can also apply a small amount of sealant around the base to prevent water damage.
