Clogged Drains? Here's What's Causing Them and How to Fix It

May 13, 2026

If you've ever stood in a slowly filling shower or watched your kitchen sink back up, you know how frustrating clogged drains can be. Homeowners in Ellensburg, WA, deal with blocked pipes more often than you might think, and the good news is that most causes are easy to identify. Understanding what leads to clogged drains and knowing your options can save you time, money, and a big headache.

The Most Common Causes of Clogged Drains

Drain blockages don't happen overnight. They usually build up over weeks or months before you notice a problem. Here are the most frequent culprits:

Grease and Food Buildup

Cooking grease may go down your drain as a liquid, but it quickly cools and sticks to the inside of your pipes. Over time, layers of grease trap food particles, creating a thick blockage. This is one of the top reasons kitchen drains back up.

  • Never pour cooking oil, bacon grease, or fats down the sink.
  • Wipe greasy pans with a paper towel before washing them.
  • Run hot water after washing dishes, but know that grease will still cling to pipes.

Hair and Soap Scum

Bathroom drains are no match for hair and soap residue. Every shower sends loose strands and soap film into your pipes. Over time, these combine into a sticky mass that slows and eventually stops water flow completely.

  • Use a drain cover or hair catcher in the shower and tub.
  • Clean the drain stopper regularly to prevent buildup.

Tree Roots

This one surprises a lot of homeowners. Tree roots naturally grow toward sources of moisture, and your underground pipes are a prime target. A small crack or loose joint in a pipe is all a root needs to get inside. Once there, roots spread quickly and can cause serious blockages, especially in older homes.

Dirt, Debris, and Mineral Buildup

Outdoor debris like leaves and dirt can enter floor drains and outdoor lines. Inside the home, hard water leaves behind calcium and mineral deposits that slowly narrow your pipes. This is common in areas where water quality includes high mineral content.

Warning Signs Your Drain Is About to Clog

Drains rarely go from perfect to fully blocked without giving you some warning.

Watch for these early signs:

  • Slow draining: Water takes longer than normal to empty from your sink, tub, or shower.
  • Gurgling sounds: A bubbling or gurgling noise from your drain often means air is trapped in the line.
  • Unpleasant odors: Foul smells coming from your drain can signal a buildup of organic material deep in the pipe.
  • Water pooling: Standing water in your shower or around floor drains is a strong warning sign.
  • Multiple slow drains at once: If more than one drain in your home is sluggish, you may have a clog deeper in your main line.

Catching these signs early can keep a minor inconvenience from turning into a plumbing emergency.

DIY Fixes That May Work (and When They Won't)

For minor blockages, a few simple methods can get things moving again:

What You Can Try at Home

  • Plunger: A basic cup plunger works well on sink and tub drains. Create a tight seal and push firmly up and down several times.
  • Baking soda and vinegar: Pour half a cup of baking soda down the drain, followed by half a cup of white vinegar. Let it fizz for 15 to 20 minutes, then flush with hot water. This works best for light, surface-level buildup.
  • Drain snake or hair removal tool: These plastic tools with tiny hooks can pull out hair and debris from just below the drain opening. They're inexpensive and very effective for bathroom drains.
  • Boiling water: For kitchen sinks, slowly pouring boiling water down the drain in two to three stages can help break up grease clogs.

When to Call a Professional Plumber

Some clogged drains are a sign of a bigger issue inside your plumbing system. A professional plumber has the tools and experience to find the true cause of the problem, not just punch a temporary hole through the blockage. They can use video camera inspections to see exactly what is going on inside your pipes, which removes all the guesswork.

You should call a professional plumber when:

  • Water is backing up into your bathtub or other fixtures when you flush.
  • You notice water damage or moisture near pipes or walls.
  • Your home is older, and the pipes may be corroded or cracked.
  • You have tried multiple DIY methods, and nothing has worked.

Waiting too long on a serious clog can lead to pipe damage, water leaks, or sewage backflow into your home, all of which are far more expensive to fix than a simple drain cleaning.
