How to Unclog a Sink Drain

Nobody wants to see a slow-draining sink because it inevitably indicates a clog in the pipe and a plumbing visit. However, a clogged sink doesn’t always require a plumber. Here are some ways to unclog your sink.

Use a Plunger

Just like with a toilet, a plunger is often enough to dislodge small clogs. Make sure that there’s enough water in the sink to cover the cup of the plunger, and (for dishwashers with a flexible hose) place a clamp over the hose to prevent backflow before plunging the sink.

Pour Boiling Water Down the Sink

Boiling water is another easy fix for small clogs. Simply boil half a gallon of water on the stove and remove standing water from the sink. Then steadily pour the boiling water down the drain, repeating the process one more time if the clog isn’t gone.

Run the Garbage Disposal

Your garbage disposal may be the source of the drain clog, so you should inspect it to make sure. Run the disposal to see if the clog is in it, and see if the clog is cleared. If there’s something stuck in the disposal, you may be able to remove it by hand after turning off power to the disposal.

Break it Up with Baking Soda

The clog might be dissolved by a mixture of equal parts baking soda and vinegar. Pour the baking soda in first, then the vinegar. Place the sink stopper over the drain and wait several minutes before flushing the mixture.

Use a Wet-Dry Vacuum

Sometimes, a clog can be sucked out of the pipe using a wet-dry vacuum. If the sink has dual basins, put a stopper on the other drain. Create a tight seal around the vacuum hose and the clogged drain, and turn the vacuum on to its highest setting.

Call a Plumber

If none of these unclogging methods work, your clogged sink is a job for the professionals. A drain plumber has special tools to unclog the drain and can remove pipes under the sink safely if necessary. 

Rather than risk damaging your plumbing system, contact the plumbers at Parker & Sons Plumbing to unclog your sink. Contact us today to schedule an appointment.

Roberta C.

Very Knowledgeable

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Stacey C.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
