Fill the sink with enough water to cover the plunger cup. Splash some water around the edges of the sink to wet them. This will help create a seal between the plunger and the sink.

Place the plunger over the slow sink drain and push it down so that the cup forms a seal. Start plunging up and down vigorously. Be sure to keep the plunger moving up and down at a steady pace – don’t stop until you’ve made 10-15 plunges. 

Once you’re finished, remove the plunger and run the water for a few seconds to see if it’s draining correctly. If not, repeat the steps until the slow-draining problem is fixed. This method is a classic solution that helps in 90% of cases. However, if even after several attempts to get rid of the water, nothing helps you, you should take something more serious.

Clean the Water Trap

The function of the water trap is to collect any water that flows down the drain so that it can’t escape into the atmosphere and cause odors. Over time, the water trap can become clogged with all sorts of things like hair, food particles, and soap scum. When this happens, it’s time to clean out the water trap.

You should:

  1. Place a bucket underneath the P-trap to catch any water that may spill.
  2. Loosen the slip nuts that connect the P-trap to the slow silk drain and overflow tube. Be careful not to drop them into the sink. You may need a wrench to loosen them. If so, place a cloth over the wrench to prevent scratching the finish on the slip nuts. 
  3. Once the slip nuts are loose, remove the P-trap and empty it into the bucket. 
  4. Rinse the P-trap with warm water and reattach it to the sink drain and overflow tube. Make sure you hand-tighten the slip nuts before using a wrench to give them an extra tight seal. 
  5. Test your work by running some water down the sink and making sure it drains quickly. If it doesn’t, check for leaks at all connections and tighten as needed. 

How to Prevent the Slow Sink Drain

You can simply keep the clog out to successfully deal with debris in the sink. For this:

  • Clean your water trap regularly to help keep your sink draining correctly and prevent odors from escaping into your home. We recommend doing this every few months or as needed.
  • If you see hair in the sink, try to always throw it in the trash instead of rinsing it off with water. Do the same with toothpaste and soap that ends up in the sink.
  • If your problem area is the kitchen and not the bathroom, then while washing the dishes, throw all the waste in the trash and only then wash the dishes. This way, you will prevent the accumulation of debris in the pipes.
  • Pour hot water into the sink drain regularly. This will help melt the soap or other mixtures. You can make this your routine during every house cleaning.

Bottom Line

As you can see, cleaning the sink of excess debris is not so difficult, but it may require a minimal investment of money and effort. In any case, even the longest procedure will take 30 minutes, and you should do something for only 5 of them. And the result will be worth the effort.

The main thing to remember about safety when working with hazardous products that can corrode waste in pipes.
