  • The Boiled Water Fix

As fat and greasy stuff tend to collect on the pipes when they get cold, the best way to remove them is to pour boiling water down the sink.

At first, you will have to pour half a cup of baking soda in the drain along with half a cup of white vinegar.

Wait for it to fizzle for a few minutes. Then pour the boiling water down the drain.This will help to melt the grease and fat coating in the pipes.

  • Plunge the Drain

This may be the most common fix you have heard of. After pouring the boiling water, plunge the drain up and down.

Then, after a while, check to see if the water drains properly.

  • Clean up the P Trap

In case you have not figured it out yet, the bent elbow-shaped pipe is the P trap. To clean up the P trap, you must disassemble it first.

Make sure you keep a bucket underneath to catch anything that falls out. Once you clean the P trap and reconnect it, make sure to check whether the water is draining properly.

  • Clean the Garbage Disposal

If you suspect the issue is within the garbage disposal, you can try plunging to remove the clog. In case that does not work, you can manually rotate the blades to clear up the clog.

Avoid inserting your hands inside the garbage disposal. Use an Allen wrench if you must or any other tool.

  • Clean the Air Vent

The air vent can get clogged by debris over time and observing some signs of a clogged drain vent pipe you can determine clearly. So, the best way to clean it is by using a drain snake.

But of course, you must disassemble it first. Also, make sure there is a proper pathway for the air to pass.

Chemical cleaners can be very harsh on the pipes, leading to corrosion over time. So, you can use natural enzymes to keep your pipes clean and avoid clogs.

  • While plunging has been suggested as a fix, avoid plunging with excessive force. Excessive force can disrupt the drainage line, which may result in leakage.
