What Causes Clogged Drains?

Different things can clog different types of drains in your Eureka, MO home, but the main causes tend to be the same. Below are the most common reasons drains clog:

Hair often causes clogs in showers, tubs, and bathroom sinks. Even tiny strands can build up and tangle with soap scum, resulting in slow, stubborn drain blockages.

Even with a garbage disposal, food waste like eggshells, coffee grounds, vegetables, rice, and other scraps don’t break down easily and pile up.

Kitchen sinks are also often clogged by grease and fat that cool and solidify inside the pipe, forming a sticky layer that narrows the drain.

Soap scum builds up from soap and mineral residue, creating a hard, sticky film inside pipes. Toothpaste scum in bathroom sinks also adds to clogs by catching hair.

Mineral buildup (hard water) affects every type of drain. The minerals build layer by layer inside the plumbing, shrinking the drain diameter.

Toilets are often clogged by items such as feminine products, wipes (even “flushable” ones), paper towels, and cotton swabs that don’t break down and get stuck in the pipe. If it’s not toilet paper, don’t flush it.

Tree roots often invade sewer lines looking for water, causing blockages throughout the entire home.

Broken or collapsed pipes, especially in older homes, let dirt and debris enter the drainage system, restricting drainage. Undersized pipes are more prone to clogging than larger lines.

Basement drains and laundry drains can be clogged by debris and sediment like sediment, lint, and tracked-in dirt that collect in the trap and form a solid clog.

Why Do My Drains Keep Getting Clogged?

Even if you unclog a drain once, it can still clog again. Repeated clogs are often a sign of a bigger problem. These are the typical causes:

  • The blockage slipped further into the pipe, and DIY fixes like plungers or store-bought cleaners aren’t able to clear it.
  • The clogs are happening because of larger problems within the line, like broken pipes or tree roots, so drains keep blocking regardless of how many times you clear the visible blockage.
  • If multiple drains — like the kitchen sink, bathroom drain, or laundry line — all connect to the same problem area, fixing one won’t solve the real issue.
  • There’s a sag or low spot in the pipe (called “bellies”), which collects debris, and the trapped material creates repeat blockages over time.
  • Everyday habits, like rinsing grease down the kitchen sink, letting hair wash down the shower drain, or flushing wipes, keep rebuilding the same type of clog even after you clear it.

How to Unclog a Drain Yourself

Before reaching out to a pro, there are a few at-home methods you can try to see if you can fix the issue on your own:

  • Try Hot Water First: Heat a pot of water and slowly send it down the drain. This can soften minor buildup in sinks and tubs.
  • Remove the Stopper or Drain Cover: Try removing anything you can access with your hand or a makeshift tool.
  • Try Dish Soap: For kitchen sinks with greasy buildup, pour a generous amount of dish soap into the drain and let it sit long enough to break down the grease.
  • Make Your Own Drain Cleaner: Mixing one cup of white vinegar and one cup of baking soda produces a bubbling effect that helps break down soft residue. Pour hot water afterward to rinse the line.
  • Use a Plunger: A few solid plunges can clear surface-level blockages in toilets, bathroom sinks, and kitchen drains. Cover the overflow opening to build pressure.
  • Use a Drain Snake / Augur: Insert the auger carefully into the pipe to grab or break through clogs.

When to Call a Professional Eureka, MO Plumber for a Clogged Drain

If the clog refuses to clear after trying DIY steps and the problem continues, you’ll want a professional plumber to take over to handle the clog the right way. These are the indicators you shouldn’t ignore:

  • DIY Methods Don't Work: If you've tried hot water, vinegar and baking soda, a plunger, an augur, or any home trick and nothing changes, you’re likely dealing with a clog that requires pro-level equipment.
  • The Clog Keeps Coming Back: When your drain works briefly then starts backing up again, there’s almost always a deeper issue in the line that requires more than basic tools.
  • Multiple Drains Are Backed Up at Once: If several drains clog at the same time, it’s typically a sewer line clog, not an isolated drain.
  • Water Is Backing Up Into Other Drains: If water is moving in the wrong direction, the main drain line is overloaded and only a plumber’s tools can fix it.
  • Complete Blockage: If the pipe is totally blocked, don’t try to power water into it, because the pipe is fully blocked and needs a plumber’s tools to clear.
  • You Can’t Access the Clog Safely: Hard-to-reach drains and older pipe layouts often need pro-level equipment to prevent breaking the pipe.
