Q: My bathroom sink is poorly drained, which drives me crazy.

Although the water finally runs out, it takes a long time — and it’s hard to use a sink full of dirty water.

What can be done for slow drainage of the sink?

A: If when brushing your teeth, you lean over a sink filled with toothpaste foam. You will face a very common problem – partial clogging.
Although frustrating, the slow drainage of the sink is easy for most homeowners to remediate themselves.

The culprit is usually a viscous mixture of swelling of soap, hair or sticky styling products. The thick shaving foam, which accumulates on the drain wall.

While you can try to get to commercial drain boilers close bats immediately. These aggressive and corrosive chemicals will irritate the skin and eyes and even hurt old pipes.

Since blocking removal usually does not take any chemicals, we recommend that you use it safely and follow the steps described here.

how to fix a slow draining bathroom : best 7 methods

1 – Clean the plugs.

Since the sink is located at the outlet of the drain, the metal glue extends a few inches of pipes.  The sink plug (a small bulging metal device used to insert the sink drain) tends to capture hair, soap and other debris.

Once this trapped rough ball gets too big, whining, you have a slow drain from the sink.

In many modern sinks, simply unscrew the plugs; in some old sinks, a small rope keeps the plugs in place.
Look under the sink, where the sink is connected to the pipe. You usually see a small stick with nuts and clips attached to the pipe. Turn the nuts to separate it – if tight, you may need pliers – tighten the clip to release the rod, then lift the drain plug.
If the plugs are covered with viscous rubbish and hair, thoroughly wipe all debris with a paper towel or rag.
But don’t just replace the plug – wait until you fix any of the obstructions before using one of the following tips.

2 – Melt the mud.

The viscous coating inside the drain pipe narrows the opening and slows down the drain.
Pour half a glass of baking soda, then pour half a glass of vinegar – foam and foam reactions help to break a small clogging.
Use a small rag to block the drain, so that the chemical reaction does not bubble everything.
After 15 minutes, the boiling water from the teapot is poured into the drain and warm water is run for a few minutes to further remove the melted mucus.

3 – Lift debris.

If cleaning the drain wall does not solve the problem, use the hairy locking tool (sometimes called the “drain cleaning tool”) to remove accumulated debris.
The tool is usually made of flexible plastic, with a handle on one end and a small spike on the other to grab hair and other debris in a clogged drain from the sink.
After removing the plug, insert the plastic pipe under the drain, avoiding and often lifting it to remove anything on the hook.
Continue to do so until you can no longer lift any obstructions.

4 – Use plunger.

Sometimes the clogging slides deeper than the drain cleaning tool, but the sink plunger can help.
For best results, connect the hole of the spill in the sink with a small rag.
Place the sink plunger in the form of a cup (instead of the toilet plunger, which has a flange for sealing the toilet outlet) into the sink drain.
Fill the container with enough water to cover the plunger cup.
Now immerse yourself in a short and fast movement, forcing as much air as possible to descend into the drain.
If the blockage comes out, you need to see that the water in the sink is quickly drained.

5 – Snake.

If you have tried all the above steps, but there is still a slow drain from the sink, then it’s time to become more active.
Collect a Drain Snake (also known as Drain Spiral Drill) from the Home Improvement Store; this metal cable extends anywhere from 3 to 25 feet in length and has a spiral closure at the other end so you can drain a lock that the sink or plunger cleaning tool cannot reach – Yeah.

After removing the plug, insert the tip of the snake into the drain of the sink.
Feed the snake below the pipe, periodically recycle to clean any accumulated garbage.
(Keep a garbage nearby when you need somewhere to dump what comes out of the drain.
) If you feel a blockage in the pipes, shake the handle of the drain snake to break and gently turn the tool back and forth to catch the blockage.
Once the snake has a little again give, remove the snake and its contents and rinse with warm water and drain.

6 – Check the trap.

and look under your sink and you will see U-shaped curves in the pipes.
This is a P trap, and while it is designed to keep a small pool standing to prevent sewer gas from backing up to your home, it is also the primary location for loose, lost rings, debris and even lost toys to accumulate.

Before starting, close the water supply to the sink and remove any items stored under the slow drain of the sink, except the bucket directly under the trap P.
In most households, the trap P is fixed by sliding nuts at each end of the bending tube.
These are usually plastic, but they can be chrome plated in old houses.
Turn the sliding nuts counterclockwise with your finger or wrench, release the sliding nuts, and lift the trap portion P from the tube.
Use your fingers with gloves, stiff brushes or unbent hanger to unfold any noticeable clogging.
When the work is finished, reinstall the water pipe, tighten the anti-slip nuts securely, do not forget to turn on the water again!

7 – Keep things flowing through some preventive maintenance.

Since the sink with slow drainage is a problem of gradual escalation over time, you can minimize the chances of a day occurring by following some basic precautions.

  • If long hair often ends in the sink, cover the cap with a plastic or silk mesh hair pick to collect hair before it falls out.


  • When you see the hair loose in the sink, throw them in the trash instead of washing them down the drain.


  • The same applies to toothpaste and soap cereals: it is better to clean than rinse.


  • Before rinsing, remove dirt and any other thick, heavy or sticky material in the trash.



  • Periodically rinse the drain with very hot water to help melt soap sludge and sludge.


  • Once every two months, remove the plug, pour a tablespoon of table salt and a quarter cup of white vinegar into the drain, rinse the mixture with warm water.
    This combination should relax stubborn garbage before it becomes clogging.
