How to Fix Airlock in Kitchen Sink Drain
An airlock in your kitchen sink drain can be frustrating and inconvenient. It occurs when air gets trapped in the pipes, preventing water from flowing freely. This can lead to slow drainage or even a complete blockage. Fortunately, fixing an airlock is a relatively simple task that can be done without professional help. In this article, we will guide you through the steps to fix an airlock in your kitchen sink drain.
Step 1: Identify the Problem
The first step is to determine if you have an airlock. If you notice slow drainage or gurgling sounds when water flows down the drain, it is likely that there is an airlock. Additionally, if water is not draining at all, it could also be a sign of an airlock.
Step 2: Gather the Necessary Tools
To fix an airlock, you will need a bucket, a plunger, and a wrench. Ensure that you have these tools ready before proceeding.
Step 3: Remove the U-Bend Pipe
Underneath your sink, locate the U-bend pipe. Place the bucket beneath it to catch any water that may spill. Use the wrench to loosen the nuts at both ends of the U-bend pipe. Once loosened, carefully remove the pipe and empty any water trapped inside it.
Step 4: Plunge the Drain
With the U-bend pipe removed, use the plunger to create a seal around the drain opening. Push up and down vigorously to create pressure and dislodge the airlock. Repeat this several times until you feel the resistance lessen.
Step 5: Reassemble the U-Bend Pipe
After successfully removing the airlock, reattach the U-bend pipe. Tighten the nuts at both ends using the wrench. Ensure that the pipe is securely in place to prevent any leaks.
Step 6: Test the Drainage
Turn on the faucet and let the water flow down the drain. Observe if the water flows freely without any gurgling sounds or slow drainage. If the problem persists, you may need to repeat the process or seek professional help.
