What Causes Clogged Drains?

Drains in your Shrewsbury, MO home can clog for a variety of reasons, but many of them come back to the same few causes. Below are the most common reasons drains clog:

Hair is a common culprit in showers, tubs, and bathroom sinks. Small strands collect and wrap around soap residue, resulting in slow, stubborn drain blockages.

Even with a garbage disposal, food waste like eggshells, coffee grounds, vegetables, rice, and other scraps tend to accumulate rather than dissolve.

Kitchen sinks are also often clogged by grease and fat that stick to the walls of the drain, forming a sticky layer that narrows the drain.

Soap scum develops as soap interacts with hard water minerals, producing buildup that grabs dirt and bacteria. Toothpaste scum in bathroom sinks also adds to clogs by catching hair.

Mineral buildup (hard water) can build up in any drain. The minerals build layer by layer inside the plumbing, making clogs form more easily.

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. Flushing anything else leads to quick blockages.

Tree roots can force their way into sewer pipes, causing blockages throughout the entire home.

Broken or collapsed pipes, especially in older homes, allow soil and particles into the line, creating repeated backups. Undersized pipes also struggle with buildup.

Basement drains and laundry drains can be clogged by debris and sediment like dirt, leaves, and lint that settle in the trap and eventually stop the flow of water.

Why Do My Drains Keep Getting Clogged?

A drain might work for a short time after you clear it, but still clog again. Repeated clogs are often a sign of a bigger problem. Here’s why it keeps happening:

  • A clog has moved deeper down the line, and DIY fixes like plungers or store-bought cleaners can’t reach it.
  • The clogs are happening because of more serious pipe issues, like broken pipes or tree roots, so drains keep blocking regardless of how many times you clear the visible blockage.
  • If several fixtures tie into one clogged portion of the line, you’ll still have problems until the shared blockage is removed.
  • There’s a dip or bend in the drain line known as a “belly”, which collects debris, and the trapped material creates repeat blockages over time.
  • Regular use patterns, like rinsing grease down the kitchen sink, letting hair wash down the shower drain, or flushing wipes, recreate the same blockage again and again.

How to Unclog a Drain Yourself

Before you bring in a professional, there are a few at-home methods you can try to see if the clog can be cleared without help:

  • Try Hot Water First: Heat a pot of water and slowly send it down the drain. This can help break up light grease and soap film in sinks and tubs.
  • Remove the Stopper or Drain Cover: Reach for visible hair, food, or debris with your hand or a bent wire hanger.
  • Try Dish Soap: For kitchen sinks with greasy buildup, send a good amount of dish soap down 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 creates carbon dioxide bubbles that helps loosen light buildup. Pour hot water afterward to rinse the line.
  • Use a Plunger: Plunging often helps remove simple clogs in toilets, bathroom sinks, and kitchen drains. Block the overflow hole for better suction.
  • Use a Drain Snake / Augur: Insert the auger carefully into the pipe to remove buildup lodged deeper in the line.

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

If your at-home fixes fail and the water still won’t move, you’ll probably need to call a plumber in Shrewsbury, MO to fix the underlying issue. Here are some signs it’s time to call:

  • DIY Methods Don't Work: When hot water, plungers, and homemade cleaners don’t make a dent, it’s likely far past where DIY tools can reach.
  • The Clog Keeps Coming Back: If the drain slows down again after a few days or weeks, the underlying cause hasn’t been fixed that needs professional equipment to remove.
  • Multiple Drains Are Backed Up at Once: If every drain seems to be struggling, the obstruction is usually deeper — not in a single drain.
  • Water Is Backing Up Into Other Drains: If flushing the toilet forces water into the shower, you’re dealing with a system-wide issue and DIY solutions won’t reach it.
  • Complete Blockage: If the drain is completely shut down, don’t force more water, because the clog is solid and compacted and needs specialized tools to fix.
  • You Can’t Access the Clog Safely: Low-level drains, older systems, or hidden cleanouts often must be handled with the right gear to prevent breaking the pipe.
