Whether it’s a slow drain, standing water, or a complete blockage, a clogged sink can disrupt your daily routines.

Addressing these clogs promptly is crucial to avoid further damage, water backups, or even costly plumbing repairs.
In this blog post, we’ll delve into the common causes of a clogged kitchen sink and provide some practical, effective solutions. Whether you’re facing standing water or a sink that’s clogged on both sides, we’ve got the tips you need to get your sink back in action without calling a plumber (at least not immediately).
Common Causes of a Clogged Kitchen Sink
There are several common culprits behind kitchen sink clogs. Understanding what causes these blockages can help you prevent them from Cleaning Guide for Home & Kitchen happening in the future.
Food Waste Build-Up
One of the most common reasons for a clogged kitchen sink is food waste. Even with a garbage disposal, bits of food, grease, and soap can build up in your pipes over time. Things like coffee grounds, eggshells, or starchy foods like potatoes can get stuck in the pipes and cause a clog.
Grease and Oil
Another major contributor to sink clogs is grease and oil. It’s tempting to pour leftover grease down the drain after cooking, but this can be a big mistake. When grease cools, it solidifies and can form a sticky block in your pipes. Over time, this grease can cause significant blockages that are difficult to clear.
Foreign Objects
Sometimes, it’s not food that’s causing the problem but foreign objects. It’s easy to accidentally drop small utensils or kitchen tools down the drain, and these can get stuck, causing an obstruction. If you’ve ever noticed a spoon or small item missing, check your sink—it might be the cause of the problem.
Aging Pipes
If your pipes are older, they may have accumulated layers of grime, rust, and scale. Over time, the diameter of your pipes may shrink, making it easier for food waste and grease to get caught, which leads to clogs. Aging pipes can also develop cracks and leaks, which could lead to blockages or other plumbing issues.
How to Unclog a Kitchen Sink with Standing Water
If you’re dealing with a clogged kitchen sink with standing water, you’re likely looking for a quick solution. Here are some methods that can help clear that pesky clog.
Use a Plunger
A plunger is a must-have tool in any household. If your kitchen sink is filled with standing water, a plunger can help dislodge the clog and get the water flowing again. Here’s how to do it:
- Make sure the sink is filled with enough water to cover the base of the plunger.
- Place the plunger over the drain, ensuring it’s sealed tightly.
- Pump the plunger up and down rapidly for about 15-20 seconds.
- Release the plunger and check if the water drains. If not, repeat the process a few more times.
Hot Water Solution
Sometimes, the clog might be due to grease or soap build-up, which can be loosened with hot water. To use this method:
- Boil a kettle of water.
- Slowly pour the hot water down the drain in stages, allowing it to work its way through the clog.
- Wait a few minutes to see if the water drains properly.
Baking Soda and Vinegar Method
This classic home remedy works wonders for mild clogs. The combination of baking soda and vinegar creates a chemical reaction that can break up blockages.
- Pour about ½ cup of baking soda down the drain.
- Follow it with 1 cup of white vinegar.
- Cover the drain and wait for about 10-15 minutes while the mixture fizzes and works on breaking down the clog.
- Flush the drain with hot water.
Drain Snake or Auger
For deeper clogs, a drain snake (or auger) is a more effective solution. These tools can reach further down the drain and grab or break up tougher blockages. Here’s how to use it:
- Insert the drain snake into the drain and slowly feed it down the pipe.
- When you feel resistance, rotate the handle to hook the clog.
- Pull the clog out carefully, and flush the drain with hot water to clear any remaining debris.
Why Is My Kitchen Sink Clogged on Both Sides?
It’s especially frustrating when both sides of your double kitchen sink are clogged. This typically means the blockage is deeper in the plumbing system, and here’s why:
Blocked Main Drain Line
If both sides of your kitchen sink are clogged, it’s likely that the main drain line is blocked. This pipe connects the sink to the rest of the plumbing system, and when it becomes obstructed, water can’t flow freely.
Shared Trap
If your sink has two basins, it’s common for them to share a single trap. If the trap becomes clogged, both sides of the sink may back up. In this case, you’ll need to check the trap for blockages and clean it out.
Multiple Clogs in the System
Another possible cause is multiple clogs within the plumbing system. In this case, the problem may not be just at the sink but somewhere in the line, such as the dishwasher drain or the main sewer line.
Solution
To resolve this issue, start by inspecting the P-trap for any visible clogs. If that doesn’t solve the problem, using a plumber’s snake to clear the drain line might be necessary.
Kitchen Sink Clogged but No Visible Clog
Not all kitchen sink clogs are immediately obvious. You might notice water backing up, but there’s no clear sign of what’s causing the issue.
Airlock in the Drain
Sometimes, a clog isn’t solid but a buildup of air in the pipes. This can cause water to back up in the sink without an obvious blockage. If you suspect an airlock, try running hot water through the system to clear it out.
Slow Drainage
If your sink is draining slowly, it might be an early stage of a clog. It’s crucial to address this issue before it becomes a full blockage.
Water Trap Problems
A malfunctioning trap or venting issue could cause water to back up without an obvious clog. The trap could be partially blocked, or the vent pipe might be clogged.
Solution
To fix this, check for partial blockages in the P-trap or vent system and clean them out.
Clogged Kitchen Sink Home Remedy
If you’re not ready to call a plumber just yet, here are some simple home remedies you can try before resorting to expensive repairs.
Baking Soda and Vinegar
This is a tried-and-tested solution for many clogs. The chemical reaction between the baking soda and vinegar helps break down grease, soap, and other build-ups.
Boiling Water
Boiling water can help loosen grease clogs. Simply pour it down the drain in stages, and it should help clear the pipes.
Plunger Use
A good ol’ plunger is your best friend when dealing with clogs. Just make sure the plunger is tightly sealed over the drain, and use firm pressure.
Dish Soap and Hot Water
If grease is the issue, try combining dish soap and hot water. This mixture helps break down greasy clogs and clear your drain.
