Common Plumbing Problems in Austin Homes (And How to Prevent Them)
October 9, 2025Preventing Clogged Drains in Austin: Tips & When to Call a Pro
In central Texas, our plumbing systems work hard to handle not just everyday use but also the harsh realities of Austin’s limestone-rich water and clay soils. Clogged drains are one of the most common plumbing issues we see. They often start as a slow drain or occasional gurgle and can quickly turn into a full-blown backup if ignored. In this guide, Flint Plumbing’s licensed professionals (M-42279) explain the most common causes of clogged drains in Austin and share actionable tips to keep water flowing freely. We’ll also cover when a DIY fix isn’t enough and it’s time to call in a professional.
Common Causes of Clogged Drains
The first step in preventing clogs is understanding what causes them. Here are the biggest culprits in our area:
- Grease and food scraps: Pouring grease or oil down the sink might seem harmless, but it congeals inside your pipes. Over time, it traps food particles and creates stubborn blockages.
- Hair and soap scum: Showers and bathroom sinks collect hair, shampoo and soap residue. These bind together and cling to pipe walls, eventually narrowing the drain.
- “Flushable” wipes and hygiene products: Despite the name, most wipes don’t break down like toilet paper. They catch on pipe joints and tree roots, causing clogs and sewer backups.
- Tree roots and shifting soil: Austin’s expansive clay soils shrink and swell with moisture, opening gaps in sewer lines. Nearby trees send roots in search of water, infiltrating joints and collapsing old clay or cast iron pipes.
- Foreign objects and kids’ toys: Curious toddlers flush toys, cotton swabs, feminine products and other non-dissolvable items that get stuck and block the pipe.
Preventive Tips for Clog-Free Drains
Keeping your drains clear doesn’t require harsh chemicals. Adopt these simple habits and maintenance tips:
- Dispose of grease properly: Let grease and cooking oil cool, pour them into a disposable container, and throw it in the trash. Wipe greasy pans with a paper towel before washing.
- Use drain strainers: Install mesh strainers over kitchen and bathroom drains to catch hair and food bits. Empty them into the trash regularly.
- Avoid flushing wipes or hygiene products: Place a covered trash bin near toilets and educate family members that only human waste and toilet paper should be flushed.
- Flush drains with hot water and vinegar: Once a month, pour a kettle of hot (not boiling) water down your kitchen drain to melt grease buildup. Follow with a cup of baking soda and a cup of white vinegar, wait 10 minutes and flush again with hot water.
- Maintain landscape and root barriers: Plant trees at least 10–15 feet from sewer lines, use root barriers when planting near pipes, and water large trees during droughts so they’re less likely to invade your sewer line.
- Schedule professional cleanings: Periodic drain cleaning by a licensed plumber uses hydro-jetting or augers to clear out buildup before it becomes a blockage. Homes with mature trees or older pipes may need annual cleanings.
When DIY Isn’t Enough: Signs You Need a Professional
Some minor clogs can be cleared with a plunger or small drain snake, but certain symptoms signal it’s time to call Flint Plumbing:
- Multiple drains are slow or backing up: If sinks, tubs and toilets all drain slowly, the clog may be in your main sewer line. DIY fixes won’t reach it, and forcing chemicals down multiple drains can damage pipes.
- Foul odors and gurgling noises: Rotten egg smells or gurgling when you flush indicate trapped sewage or air in the line. This often points to a deeper problem like a collapsed pipe or root intrusion.
- Water backing up in the shower when you flush the toilet: Cross-drain backups suggest a blockage in the shared waste line. Don’t attempt to flush it away; you risk flooding your home.
- Recurring clogs in the same drain: If you’re plunging the same sink every month, there is likely a larger obstruction or damaged pipe that needs a professional inspection with a camera.
- Old or shifting pipes: Austin’s older homes often have clay or cast iron sewer lines that crack over time. If your home is 30+ years old or you’ve had foundation repairs, a professional assessment is wise.

At Flint Plumbing, we use video cameras to inspect your lines and hydro-jetters to scour them clean. We can also repair or replace damaged sections to prevent future clogs.

Frequently Asked Questions
What can I pour down a clogged drain to unclog it?
For minor grease clogs, try a mixture of hot water, baking soda and vinegar. Avoid over-the-counter chemical drain cleaners as they can corrode pipes. If a plunger and these natural solutions don’t work, call a professional.
Are “flushable” wipes safe for my plumbing?
No. Despite marketing claims, flushable wipes don’t break down like toilet paper. They accumulate in pipes and sewer systems, causing blockages and expensive repairs. Always dispose of wipes in the trash.
Why do tree roots grow into sewer lines?
Tree roots seek moisture and nutrients. If your sewer line has small cracks or poorly sealed joints, roots can penetrate and thrive. Over time, they expand and block or break the pipe. Root barriers and regular inspections help prevent this.
How often should I have my drains professionally cleaned?
It depends on the age of your plumbing and the number of occupants in your home. Homes with older pipes, large families or mature trees benefit from annual cleanings. At minimum, schedule a professional inspection every 2–3 years.
