Drain Clogs: What’s Causing Them—and How to Fix Them Fast

Drain Clogs: What’s Causing Them—and How to Fix Them Fast

A clogged drain always seems to happen at the worst possible time—right before guests arrive, during a busy morning, or late at night when everything is closed.

Whether it’s a slow drain or a complete backup, one thing is certain: you want it fixed quickly and correctly.

At OnCall Plumbing, we help homeowners across Liberty Hill, Austin, and Central Texas clear drain clogs fast—and prevent them from coming back.

What Causes Drain Clogs?

Most drain clogs don’t happen overnight—they build up over time. Here are the most common causes we see:

Kitchen Drain Clogs

• Grease, fats, and oils

• Food scraps

• Soap residue

Grease is one of the biggest culprits. It may go down as a liquid, but it hardens inside your pipes and traps other debris.

Bathroom Drain Clogs

• Hair buildup

• Soap scum

• Toothpaste residue

Hair binds with soap and creates stubborn blockages, especially in showers and tubs.

Toilet Clogs

• Too much toilet paper

• “Flushable” wipes (which aren’t actually flushable)

• Hygiene products

Toilets are designed for waste and toilet paper only—anything else can cause a blockage.

Signs You Have a Drain Clog

Not all clogs are obvious at first. Watch for these early warning signs:

• Slow draining water

• Gurgling sounds in pipes

• Water backing up in sinks, tubs, or toilets

• Unpleasant odors coming from drains

• Multiple drains clogging at once

If you notice more than one drain having issues, it could be a deeper problem in your main sewer line.

Quick Fixes You Can Try First

Before calling a plumber, there are a few safe methods you can try:

1. Use a Plunger

A sink or toilet plunger can often clear minor clogs by creating pressure to push the blockage through.

2. Try a Drain Snake

A hand auger or drain snake can help pull out hair and debris from bathroom drains.

3. Hot Water + Dish Soap

For grease clogs, pour hot water mixed with dish soap down the drain to help break it up.

⚠️ Avoid chemical drain cleaners—they can damage your pipes and often don’t fully solve the problem.

When to Call a Professional

If the clog won’t clear—or keeps coming back—it’s time to call a professional.

You should call OnCall Plumbing if:

• Water is backing up into your home

• Multiple drains are clogged at once

• You smell sewage odors

• DIY methods aren’t working

• The clog returns repeatedly

These are signs of a deeper issue that requires professional tools and expertise.

How to Prevent Future Drain Clogs

The best way to deal with clogs is to prevent them in the first place.

Here are a few simple tips:

• Never pour grease down the drain

• Use drain screens to catch hair and debris

• Only flush toilet paper

• Run hot water after using sinks

• Schedule routine drain cleaning

A little prevention goes a long way in avoiding costly plumbing problems.

Don’t Wait Until It Gets Worse

A slow drain might not seem like a big deal—but it’s often the first sign of a larger issue.

Ignoring it can lead to:

• Full drain backups

• Pipe damage

• Sewage overflow

• Expensive repairs

The sooner you address a clog, the easier (and cheaper) it is to fix.
