How to fix a sink that drains slowly

A sink that drains slowly can be a frustrating problem, often caused by a buildup of debris, soap scum or even mineral deposits. Fortunately, you can sometimes fix this problem without calling a plumber. With a few simple tools and techniques, you can restore proper drainage and keep your sink running smoothly.

Remove and clean the clog

Many sinks have an automatic stopper that collects hair and dirt over time. To remove the stopper, look under the sink and unscrew the pivot rod that holds it in place. Once removed, clean out the accumulated dirt and rinse it thoroughly before reinstalling it.

Use boiling water

Boiling water is a simple and effective way to remove soap and grease build-up from pipes. Carefully pour a pot of boiling water down the drain and wait a few minutes to see if drainage improves. Repeat this step if necessary.

Use a plunger

A sink plunger can help unclog by creating suction. Place the plunger over the drain, making sure it is tightly sealed, and pump it forcefully up and down. Let the water run to see if the drain becomes unclogged.

Use a drain snake or wire hanger

If the clog persists, use a drain snake or straightened wire hanger to remove trapped debris. Insert it into the drain and twist it to remove any clogs. Be careful not to damage the pipes.

Check and clean the P-siphon

The P-siphon is the curved pipe under the sink that can accumulate debris over time. Place a bucket underneath to catch the water, unscrew the fittings and remove the siphon. Clean it thoroughly before replacing it.

Prevent future clogs

To prevent slow drainage in the future, avoid flushing grease, coffee grounds or large food particles down the drain. Use drain covers to catch hair and debris, and regularly flush the drain with hot water to keep it clean.

Conclusion

Fixing a sink that drains slowly is a manageable task with the right approach. By cleaning the clog, using natural solutions, unclogging or even checking the P-siphon, you can restore proper drainage and prevent future clogs. Regular maintenance will ensure that your sink remains smooth and functional.
