Why Is My Drain Clogged?
A slow or clogged drain is one of the most common plumbing problems homeowners face. Whether it's your kitchen sink, bathroom sink, shower, or tub, a clog can quickly go from a minor annoyance to a major headache.
Here are some of the most common reasons your drain may be clogged—and what you can do about it.
Bathroom Drains: Hair Is Usually the Culprit
Hair is the number one cause of clogged bathroom drains. Over time, hair combines with soap scum, toothpaste, and other debris to form a stubborn blockage that slows or completely stops water from draining.
Signs of a hair clog include:
Water draining slowly.
Standing water in the shower or sink.
Gurgling sounds.
Unpleasant odors coming from the drain.
What you can do:
Remove visible hair from the drain.
Try using a drain snake or zip tool.
Avoid chemical drain cleaners, as they can damage your pipes over time.
Kitchen Drains: Grease Is the Biggest Offender
Many people think it's okay to pour hot grease down the drain because it's liquid. Unfortunately, once that grease cools, it hardens inside your pipes and traps food particles, creating a stubborn clog.
Other common causes include:
Coffee grounds
Rice and pasta
Eggshells
Fibrous vegetables like celery
Food scraps that should have gone in the trash
Prevention tips:
Pour cooking grease into a disposable container instead of the sink.
Use a sink strainer to catch food particles.
Run plenty of cold water when using your garbage disposal.
Toilets Can Clog Too
A toilet is designed to handle only human waste and toilet paper. Flushing anything else can lead to a blockage.
Common offenders include:
"Flushable" wipes
Paper towels
Feminine hygiene products
Cotton swabs
Excessive amounts of toilet paper
If your toilet clogs frequently, there could be a larger issue deeper in the drain line.
Tree Roots Can Invade Sewer Lines
If multiple drains in your home are backing up at the same time, the problem may not be inside your house at all.
Tree roots naturally seek moisture and can enter tiny cracks in underground sewer pipes. Once inside, they continue growing until they partially or completely block the line.
Warning signs include:
Several drains backing up at once.
Toilets bubbling when another fixture is used.
Sewage odors.
Water backing up into tubs or showers.
This type of clog usually requires professional equipment such as a sewer camera inspection and hydro jetting.
Can I Use Chemical Drain Cleaners?
While they're heavily advertised, chemical drain cleaners often do more harm than good.
They can:
Damage older pipes.
Harm plumbing fixtures.
Create safety hazards for anyone working on the drain later.
Fail to remove the actual blockage.
A mechanical drain cleaning is typically safer and more effective.
How to Help Prevent Drain Clogs
A few simple habits can save you from costly plumbing repairs:
Keep hair out of bathroom drains with drain screens.
Never pour grease or oil down the sink.
Scrape food into the trash before washing dishes.
Only flush toilet paper and human waste.
Have your drains professionally cleaned if they begin slowing down.
