A kitchen sink that won’t drain is a common problem. It can be very annoying. Water stays in the sink. Food and dirt block the pipes. This causes slow or no drainage. You might not know what to do. This guide will help you fix it step by step.
Why Does Your Kitchen Sink Not Drain?
Many things can stop your sink from draining. The most common reasons are food scraps, grease, and soap buildup. Sometimes small objects fall into the drain. Hair and dirt also cause clogs. Grease can harden and block pipes. Understanding the cause helps you fix the problem faster.
First Steps: Check the Simple Things
Before you start, look under the sink. See if there is any water leaking. Check the pipes for damage. Sometimes the pipes are loose or broken. Tighten any loose parts. If nothing looks wrong, try these simple methods.
1. Use Boiling Water
Boiling water can melt grease and soap. Boil a kettle of water. Slowly pour the hot water into the drain. Do this in stages. Wait a few seconds between each pour. This may clear minor blockages.
2. Use A Plunger
A plunger works well for many clogs. If your sink has two basins, cover the other drain with a wet cloth. This stops air from escaping. Put the plunger over the drain opening. Push down and pull up quickly several times. Then, lift the plunger and see if water drains. Repeat if needed.
Try Natural Cleaning Solutions
If boiling water and plunging don’t work, try baking soda and vinegar. This is safe and easy.
How To Use Baking Soda And Vinegar
- Pour half a cup of baking soda into the drain.
- Pour half a cup of white vinegar into the drain.
- Let the mixture sit for 15 minutes. You will see bubbles and fizz.
- After 15 minutes, pour hot water down the drain to flush it.
This method helps break down grease and dirt. It also cleans the pipes.
Use a Drain Snake for Stubborn Clogs
Sometimes the clog is deep inside the pipe. You need a drain snake or auger. This tool is long and flexible. It can reach and break the clog.
How To Use A Drain Snake
- Insert the snake into the drain opening.
- Push gently until you feel resistance.
- Turn the snake to break up the clog.
- Pull the snake out slowly.
- Run water to check if the drain is clear.
If you do not have a drain snake, you can buy one at hardware stores. They are not expensive.
Clean the P-Trap
The P-trap is a U-shaped pipe under the sink. It holds water to stop sewer gases. It also collects small clogs. Cleaning it often fixes drainage problems.
Steps To Clean The P-trap
- Place a bucket under the P-trap to catch water.
- Use a wrench or your hands to unscrew the slip nuts on each side.
- Remove the P-trap carefully.
- Check inside for clogs or debris.
- Clean the pipe with a brush or cloth.
- Reattach the P-trap tightly.
- Run water to test if it drains well.
Be careful when removing the trap. Water inside can spill.
Use a Wet-Dry Vacuum
A wet-dry vacuum can suck out clogs. It works best on clogs near the drain.
How To Use A Wet-dry Vacuum
- Set the vacuum to wet mode.
- Cover the vent to avoid mess.
- Place the vacuum hose over the drain.
- Create a tight seal with a wet rag if needed.
- Turn on the vacuum at high power.
- Try to suck out the clog.
- After a few minutes, check if water drains.
When to Call a Plumber
If none of these methods work, it is time to call a plumber. Some clogs are deep or complex. Plumbers have special tools. They can fix the problem safely and fast. Trying to force the clog may cause pipe damage.
