Method 2: Plunger


Clogged drains could be unclogged using the plunger technique, which is an excellent home treatment.

The majority of families have a plunger stashed away in the bathroom.

If you are unable to locate one in your house, they may be purchased at a reasonable price at any nearby home improvement shop. When there is a major clog, the plunger method is the most effective.

To begin, make certain that you are using a cup-shaped plunger rather than a grooved plunger. Even if you have a handheld or a full length plunger, it is also suitable for this method.

Make sure that any metal strainers in the kitchen sink or bathroom sink have been removed prior to starting your cleaning project. This step guarantees that the plunger can be used to create a secure seal on the sink drain.

Make sharp, quick motions to clear the blockage, and then check in on it occasionally to see whether it has been successful.

  •  You should cover the entire sink drain with the help of your sink plunger.
  •  For roughly 1 minute, it is recommended to press and pull the plunger in a rapid motion.
  •  Alternatively, if the water is draining poorly, add some additional water to the drain before plunging it again.
  •  If somehow the water drains quickly, you’ve taken the proper step.

Method 3: Vinegar and Baking Soda

Vinegar and Baking Soda

If the blockage continues after you’ve tried the boiling water approach, try a vinegar and baking soda solution.

  • To begin, sprinkle one cup of baking soda into the sink‘s drain. There is no need to pour any water.
  • After that, one cup of white vinegar should be poured down the drain hole.
  • Drains should have a stopper or cover installed to keep the water out.
  • Allow 30 minutes for the solution to rest.
  • Next, you have to remove the drain cover and flush the drain with hot tap water to clean it.
  • More severe clogs should be broken up using hot water.
  • Just like any unclogging approach, there is no guarantee that this natural option will work 100 percent of the time.

Reasons of Clogs

Sinks and bathtubs could get blocked as a result of debris being flushed down the drain.

Hair is the most common problem of a bathtub drainage clog because it may clump together and create a compact block, but soap scum, grime, and other material that you rinse off your body could also accumulate in the cluster.

Bathroom sinks may get blocked as a result of hair and other beauty items that may be washed down the kitchen sink drain.

Food is a major cause of clogged drains in the kitchen, especially grease that solidifies in the pipelines and bits of food which flow down the sink drain.

Depending on how much gunk has accumulated, you could find that the water is draining more slowly than usual.

It may ultimately get so blocked that no water can pass through it, resulting in a pool of water in the middle of the pipe.

Some clogged sink could be cleared out with hot water, but you must take care while dropping warm or boiling water into drains or toilets.

Plastic plumbing parts might be damaged or weakened as a result of the heat.

Extra water, on the other hand, will not assist in a scenario where there is already standing water and may even make the issue worse.

Commercial and household drain cleaners, such as vinegar and baking soda, will not likely pass through the water and penetrate the blockage in this situation.

The most successful techniques of removal are often mechanical in nature.
