How To Fix A Gurgling Kitchen Sink: A Few Basic Steps And Techniques

Are you getting frustrated with your gurgling kitchen sink? You’re not alone! Many homeowners face this problem at some point in their lives.

Thankfully, fixing a gurgling kitchen sink doesn’t have to be a huge ordeal. With a few simple steps and supplies, you can get your sink running normally again in no time.

In this article, we’ll cover how to:

  • identify the cause of the gurgling
  • assemble the supplies needed
  • remove the drain trap
  • clear the clog
  • test the drain
  • replace the drain trap
  • inspect for further problems.

Let’s get started!

Identifying the Cause of the Gurgling

Identifying the source of the noise is the first step in solving the problem – don’t wait any longer, start finding out what’s causing the gurgle now!

Start by plugging any leaks or cracks around the sink, as these can lead to air bubbles in the pipes. Check the entire sink area, including the faucet, drain, and pipes, to make sure there are no cracks or gaps that could be causing the gurgle.

Examine the pipes, too, as a blockage in the drain or a clog in the pipes can lead to gurgling noises. If these steps don’t work, you may need to call a plumber to check the pipes and drain for a deeper issue.

With a few simple steps, you can easily identify the source of the gurgling and get it fixed quickly.

Assembling the Supplies

To get started on this project, gather your supplies – it won’t take long! Get together a few items, such as:

  • Plumber’s tape
  • A basin wrench
  • Adjustable wrench
  • Screwdriver

Once you have the supplies, you can start to identify the parts of the sink. Take a look around the sink and find the drain pipes, P-trap, and the tailpiece.

The P-trap is the U-shaped pipe, which connects the sink drain to the drain pipe. The tailpiece is connected to the P-trap and the drain stopper. Once you’ve identified all the parts, you can begin to loosen them and remove them.

Removing the Drain Trap

Ready to start fixing that sink? Let’s begin by removing the drain trap!

To remove the drain trap, you’ll need to locate the slip nut and loosen it with a wrench. There should also be a slip nut at the other end of the trap, which you’ll need to loosen as well.

Be sure to wear gloves to protect your hands from any drainage blockages or debris from the sewer line. Once both nuts are loose, you can easily remove the drain trap.

If you find that the nuts are stuck, you can try using a pair of pliers or a pipe wrench to help you loosen them. If that doesn’t work, you may need to use penetrating oil to get them to move.

Once the drain trap is removed, clean it out and inspect it for any damage. If it looks okay, you’re ready to move on to the next step.

Clearing the Clog

Now that the drain trap is out of the way, it’s time to tackle the clog. Put on some old clothes and grab a few tools, it’s time to get down and dirty!

The first step in unclogging a kitchen sink is to use a plunger. Place the plunger over the drain, and press down firmly and quickly. Repeat this motion several times to help loosen the clog.

You can also try using a plumber’s snake to clear the blockage. This is a long, flexible metal rod that can be pushed through the pipe in order to unclog the blockage. Make sure to use a gentle hand when using the snake, as you don’t want to cause any further damage.

Finally, you can try using a chemical drain cleaner to clear the clog. However, be sure to carefully read the instructions on the product to ensure you’re using it correctly and safely.

To prevent future blockages, you can use a sink strainer to trap debris before it goes into the drain. Additionally, you can avoid pouring grease and oils down your kitchen sink, as these can cause clogs.

Finally, you can pour boiling water down the drain once a week to help keep it clean and clear. By following these steps, you can avoid future kitchen sink clogs.

Testing the Drain

Breathe a sigh of relief – let’s test the drain and make sure that all that hard work paid off!

First, make sure that you’ve properly vented the drain pipe. If you haven’t, the sink won’t drain properly and you may end up with a gurgling sound.

If the venting is correct, pour a couple of cups of water into the sink to test the draining. If the water drains out quickly, without gurgling or bubbling, your clog is gone and your sink is working properly again.

If there’s still some gurgling or bubbling, the clog may not be completely cleared and you may need to try another method.

Replacing the Drain Trap

Having tested the drain and determined the clog was cleared, it’s now time to replace the drain trap to ensure the kitchen sink is operating optimally. Replacing the drain trap requires some basic plumbing skills and tools, so it’s important to understand the entire process before starting.

Here are four steps to replacing the drain trap:

  1. Turn off the water by shutting off the valves beneath the sink.

  2. Disconnect the existing trap by loosening the slip nuts on either end.

  3. Remove the old trap and inspect it for any damage.

  4. Install the new trap and reconnect the slip nuts.

Investigating blockages and checking connections are key steps in replacing the drain trap.

Once the trap is installed and the slip nuts are tightened, turn on the water valves and check for any leaks. After the trap has been replaced, the kitchen sink should be working optimally and the gurgling should be resolved.

Inspecting for Further Problems

Inspecting the sink further can help you identify any other issues, so you can get your sink back in perfect shape. This type of preventative maintenance can help you find possible solutions before the issue develops into a bigger problem.

Take a look at the pipes to make sure they’re still securely in place. Also, check for any cracks or leaks, as these can be signs of a bigger issue. If you notice any of these, it’s best to contact a plumber for assistance.

Additionally, check for any clogs or blockages in the pipes, as these can lead to water backing up in the sink. If you find any, you can use a drain cleaner or a plunger to try and clear them out.

Finally, make sure to check the pipes for any corrosion or damage, as this can lead to a bigger problem down the line. If you find any corrosion, then it might be best to replace the pipes entirely.

Taking the time to inspect your kitchen sink after replacing the drain trap can help ensure that you don’t have any further problems.
