How To Clear a Slow-Draining Sink in Minutes

Slow-draining sinks are a common household nuisance. Soap scum, food debris, grease, and hair can build up over time in kitchen and bathroom sinks, causing them to drain slowly or clog completely.

In this post, Covenant Plumbing in Bloomington, Illinois, shares some effective tips on how to clear a slow-draining sink.

Sink Blockage Removal Methods

Here are some methods to tackle drain cleaning without using harsh and potentially harmful chemical products.

Using Baking Soda and Vinegar

This natural method is often effective in unclogging sinks. Follow these steps:

  1. Boil Water: Boil a kettle of water and carefully pour the hot water directly into the drain.
  2. Add Baking Soda: Pour a half-cup of baking soda directly into the drain. Ensure the stopper is fully open if working on a bathroom sink.
  3. Add Vinegar: Mix a cup of white vinegar with a cup of hot water and pour it into the drain. The mixture should bubble and fizz, breaking down the clog-causing material.
  4. Cover the Drain: Cover the drain with a plug and wait for 10 minutes.
  5. Add More Boiling Water: Boil another kettle of water and pour it into the drain.
  6. Flush the Drain: Run hot water from the tap to see if the drain has cleared. Repeat the process if necessary.

Using Dish Detergent

Dish detergents with strong grease-cutting power can help fix slow-draining kitchen sinks. Here’s how:

  1. Add Detergent: Pour a half-cup or full cup of dish detergent into the drain.
  2. Wait: Let the detergent sit for 30 minutes to break down the grease.
  3. Boil Water: Boil a kettle of water and pour it into the drain.
  4. Flush the Drain: Run hot water from the tap to see if the drain has cleared. Repeat the process if necessary.

Using a Plunger

Here’s how to use a standard plunger to clear a slow-draining sink:

  1. Remove Standing Water.
  2. Position the Plunger: Place the plunger over the drain.
  3. Plunge: Push and pull the plunger handle for about a minute.
  4. Run the Water: Turn on the tap to see if the drain has cleared.

When To Call for Professional Plumbing Services

If none of these methods clear the clog, it’s time to call the experts at Covenant Plumbing in Bloomington, Illinois, for assistance in clearing the sink and assessing whether there are any other problems present.

Preventative Measures

Here are some tips for preventing sink clogs:

  • Clean Bathroom Stoppers Regularly: Remove and clean the stopper to prevent hair and debris buildup.
  • Avoid Putting Grease or Large Food Pieces into the Drain.
  • Use a Mesh Drain Cover.
  • Flush the Drain Regularly: As part of routine cleaning, flush your drains with hot water.

Colton was my service technician. He arrived exactly on time for the scheduled appointment and had a very pleasant personality. He asked to see the plumbing issue I originally contracted Covenant to fix - he immediately observed the problem and provided several avenues to repair the problem. Additionally, Colton inquired if I had other plumbing issues - and I did. I showed him a whole house filter located in the basement that I wanted removed. He provided me with a reasonable quote and I let him go to work. He quickly identified that one of the problems we were having with the master bath shower was a result of it not being installed correctly when the home was built 10 years ago. So in addition to replacing the shower faucet cartridge he also corrected the plumbing issue on the shower head. Next, he removed the filter in the basement (the size of a small water heater), modifying the pipes around it and then carried it out to his van to dispose of it at Covenant’s facility. I also had several questions about plumbing in my Florida home and Colton shared a website that sells exactly what I was looking for. I am very satisfied with the professionalism, price and cleanliness of Covenant’s service. I highly recommend them for your plumbing needs.
Response from the owner:Thank you for the awesome review, Ken! Glad we could be of service.
Darren was very polite and knowledgeable. He processed a good work ethic and I would like to thank you for sending him out. The estimate was fair and he gave me information along the way. I would like to see him back for the whole house maintenance. Thank you. John Ried
Response from the owner:Thank you so much, John for taking the time to share your experience with us! We truly appreciate it.
I now understand why Cameron has 5 stars! I had such a wonderful experience with Covenant Plumbing with a pretty challenging bathroom leak situation in my 70 year old home. Cameron is so knowledgeable and good at what he does. He explained the process and the repair to me so I would feel comfortable with his work. I will be using this company again. Their communication is excellent and I feel great about the repair done in my home! Thank you. Ellen

The plumbers did a partial rebuild and replaced the Emergency Shutoff Valve. They were very professional and it didn't even take them an hour to complete the job. They walked me through what needed to be done and the pricing was reasonable. I will be using them again for any plumbing issues in the future.
