Houston Drain Cleaning Guide: When to Call a Plumber

Houston Drain Cleaning Guide: When to Call a Plumber

Clogged drains are the most common plumbing service call we receive across Houston. While some clogs respond to simple DIY fixes, others are symptoms of larger plumbing problems that require professional equipment. Here's how to tell the difference — and why we strongly advise against chemical drain cleaners.

#

The Truth About Store-Bought Drain Cleaners

We'll say it plainly: store-bought chemical drain cleaners (Drano, Liquid-Plumr, etc.) do more harm than good in most situations.

Why we don't recommend chemical drain cleaners:

- They generate heat as they work, which softens and weakens PVC pipes over time
- They're highly caustic — dangerous to handle, dangerous if splashed in eyes
- They rarely clear the root cause of a blockage; they just punch a temporary hole through it
- They can cause chemical burns if you need to follow up with a plumber
- Repeated use corrodes older galvanized and cast iron pipes, which are common in Houston's older neighborhoods

The only situation where a chemical cleaner might be acceptable: a slow drain with minor organic buildup, used no more than once or twice a year, in PVC or copper pipes.

DIY-Appropriate Clogs

These situations are reasonable to attempt yourself:

- Single slow drain with gradual onset (likely soap, hair, or grease buildup)
- Toilet clog with a plunger (cup plunger for sinks, flange plunger for toilets)
- Pop-up stopper in a bathroom sink (these collect hair and are easy to clean)
- P-trap cleaning under a sink (requires removing the curved pipe under the drain)

When to Call A Plumber Service

Call us when you see any of these:

Multiple slow or clogged drains — when more than one drain is affected, you likely have a main sewer line blockage, not just individual drain clogs. This requires a sewer machine or hydro-jetter, not a plunger.

Gurgling sounds from drains after flushing — gurgling indicates air being forced back through your drain lines, a sign of a downstream blockage or venting problem.

Water backing up into other fixtures — toilet water rising when the shower is on, or water appearing in the tub when you run the washing machine, indicates a main sewer line issue.

Recurring clogs in the same drain — if a drain keeps clogging despite your best efforts, there's a persistent blockage (often root intrusion, grease buildup, or a pipe offset) that needs a camera inspection.

Any sewage odor — sewage smells inside your home require immediate professional attention. Don't delay.

What Professional Drain Cleaning Looks Like

Drain snake (auger): For simple blockages — hair, soft organic matter — a cable auger physically breaks up or retrieves the clog. Good for single drains.

Hydro-jetting: High-pressure water (up to 4,000 PSI) blasts away grease, scale, and debris completely. This is the most thorough method and what we use for main sewer line cleaning and preventive maintenance.

Camera inspection: For persistent or mysterious blockages, we run an HD camera through your sewer line to see exactly what's happening — root intrusion, pipe offset, cracked pipe, or grease buildup.

#

Houston-Specific Drain Issues

Grease buildup is extreme in Houston kitchens. Our BBQ culture means more grease going down kitchen drains. We recommend never pouring cooking oil or grease down any drain.

Root intrusion is widespread in Houston's older neighborhoods (Bellaire, Montrose, Heights, Pasadena). Tree roots seek water and enter sewer lines through any crack or joint gap.

Clay soil settling causes pipe bellies (sections of sewer pipe that sag and collect waste) over time in many Houston neighborhoods.
