Clogged Drain Causes and Fixes

What Usually Clogs a Drain

The cause depends on the fixture.

• Kitchen: grease, food scraps and soap residue.
• Bathroom sink and tub: hair, soap scum and toothpaste.
• Toilet: too much paper or flushed wipes.
• Main line: roots, buildup or a damaged pipe.

Safe DIY Fixes

These steps are low risk for a single slow drain.

• Use a plunger with a good seal.
• Remove and clean the stopper or strainer.
• Flush with hot water, not boiling, for grease buildup.
• Use a drain snake for hair near the opening.

Avoid repeated harsh chemical cleaners. They can damage older pipes and are hard on your skin and eyes.

Signs You Need a Plumber

Call a pro if multiple drains are slow, water backs up in another fixture, odors persist or the clog keeps coming back. A plumber can snake the line, run a camera and use hydro jetting to clear buildup.

Frequently Asked Questions

Are chemical drain cleaners safe?

Occasional use may clear a minor clog, but repeated use can damage pipes. Mechanical methods are safer.

Why does my drain keep clogging?

A deeper blockage, grease buildup or a pipe problem may be the cause.

What is hydro jetting?

High-pressure water that scours the inside of the pipe to remove buildup.

Can wipes labeled flushable clog pipes?

Yes. They often do not break down and can cause blockages.
