How to Tell If Your Drain Is Just Clogged—or Keeping You Up at Night

Manuel Torres • June 13, 2025

If you're dealing with a slow-draining sink or a gurgling shower, you’re not alone. Clogged drains are among the most common—and frustrating—plumbing issues for homeowners in Coupland, Austin, and surrounding Texas communities. But how do you know if it’s a simple clog… or the beginning of a more serious issue?


At CMM Plumbing, we help homeowners spot early warning signs, tackle stubborn clogs, and prevent costly backups. Here’s everything you need to know to diagnose the problem—and what to do next.


What Causes Drain Clogs in Central Texas Homes?


Understanding what causes clogs can help you avoid them in the future. Some of the most common culprits include:


  • Hair and Soap Scum: This is especially prevalent in bathroom sinks and showers.
  • Grease and Food Waste: In kitchen drains—even with garbage disposals.
  • Hard Water Buildup: Central Texas is known for its hard water, which leaves mineral deposits in your pipes.
  • Foreign Objects: Small toys, hygiene products, and even excessive toilet paper.
  • Tree Roots: Older homes often suffer from invasive roots cracking sewer lines.



Over time, these materials accumulate, reducing the flow. If not addressed early, they can lead to backups and burst pipes.

Signs You’re Facing a Major Backup:


A single slow drain is annoying—but when multiple fixtures start acting up, it’s time to take a closer look. Watch for these red flags:


  • Slow Drains Throughout the House: This may indicate a blockage in the main sewer line.
  • Foul Odors: A musty or sewage-like smell often signals organic buildup or sewer gas escaping through vents.
  • Gurgling Noises: Air trapped in your pipes from partial clogs can cause loud bubbling or sucking sounds.
  • Water Backing Up in Odd Places: If flushing a toilet causes water to rise in the shower, it’s not just a clog—it could be a serious system issue.
  • Recurring Clogs: If you're plunging the same sink every few weeks, the problem might be deeper in the pipes.


If any of these symptoms sound familiar, it’s time to call in the pros before the problem escalates.


DIY Drain Fixes You Can Try First


Sometimes, a minor clog can be handled without a call to the plumber. Here are a few safe methods to try:


1. Boiling Water


Pouring boiling water into the drain can help melt and loosen minor grease or soap buildup.


2. Baking Soda and Vinegar


A natural, chemical-free combo. Pour 1/2 cup of baking soda, followed by 1 cup of vinegar. Let it fizz for 15–30 minutes, then flush with hot water.


3. Plunger


Use a flange plunger for toilets or a cup plunger for sinks. Create a tight seal and use firm, repetitive motions to ensure a secure fit.


4. Drain Snake or Zip-It Tool


These tools pull out hair and debris from bathroom drains. They’re inexpensive and can save you from calling a pro for simple fixes.


⚠️ Avoid chemical drain cleaners—they can corrode your pipes and make future clogs worse.


When to Call a Professional Plumber


If you’ve tried these steps and the drain is still slow or clogged, it’s time to seek professional help. At CMM Plumbing, we utilize advanced tools, including drain cameras and hydro-jetting, to safely diagnose and clear stubborn blockages.


Call us if:


  • The same drain clogs repeatedly
  • Multiple drains are slow at once
  • You smell sewage or rotten eggs
  • DIY fixes aren’t working
  • You suspect a tree root intrusion or collapsed pipe


We provide fast, affordable service across Coupland, Austin, Round Rock, Taylor, and nearby areas—and we’re available 24/7 for emergencies.


Preventing Future Clogs: Pro Tips


Prevention is key when it comes to plumbing. Here’s how to keep your drains flowing freely year-round:


1. Use Drain Strainers


Catch hair and food scraps before they enter your pipes.


2. Avoid Pouring Grease Down the Sink


Cool it in a can and throw it away—grease is a primary cause of clogs.


3. Flush Drains with Hot Water Weekly


It is instrumental in homes with hard water buildup.


4. Install a Water Softener


Hard Water Water causes mineral buildup inside pipes and appliances. A water softener can reduce clogs and extend the life of your plumbing.



5. Schedule Annual Maintenance


Professional inspections catch issues before they become emergencies. CMM Plumbing offers convenient maintenance plans designed for Texas homes.

Real-Life Example: What a Hidden Clog Looks Like


One Georgetown customer had been dealing with a slow kitchen sink for over a year. After multiple DIY fixes and store-bought cleaners failed, they called us. Our inspection revealed a massive grease clog deep in the main line. With hydro-jetting, we cleared the pipe completely—and installed a grease trap to prevent future buildup.


What is the moral of the story? Early professional help can save you money and headaches.
