Many people assume the original drain cleaning didn’t work. In reality, the drain may have been opened successfully, but the underlying cause of the blockage was never fully addressed.
If your sink, shower, tub, toilet, or sewer line continues experiencing recurring clogs, it’s important to understand why the problem keeps returning and what solutions may provide longer-lasting results.
What Does Drain Snaking Actually Do?
A drain snake is designed to break through or pull out a blockage so water can flow again.
In many situations, drain snaking is extremely effective. Hair clogs, paper blockages, small obstructions, and localized drain issues can often be resolved quickly using professional drain cleaning equipment.
However, a drain snake does not necessarily clean the entire interior surface of the pipe.
Think of it like poking a hole through a traffic jam rather than clearing the entire roadway.
Common Reasons Drains Keep Clogging
Grease Buildup
Kitchen drains are especially vulnerable to grease accumulation.
Although grease may leave the sink as a liquid, it often cools and solidifies inside the pipe. Over time, grease collects additional debris, narrowing the drain until recurring clogs begin developing.
A drain snake may temporarily restore flow but often leaves much of the grease coating behind.
Soap Scum and Residue
Bathroom drains frequently accumulate soap residue, body oils, hair, and mineral deposits.
Over time these materials form a sticky layer along the pipe walls that traps additional debris.
Even after a drain is snaked, these deposits may remain inside the pipe.
Tree Root Intrusion
For sewer lines, one of the most common causes of recurring blockages is tree root intrusion.
Roots naturally seek moisture and can enter small cracks or joints within underground sewer pipes.
Once inside, they continue growing and catching debris flowing through the line.
Snaking may temporarily cut through some roots, but the roots often return unless the underlying problem is addressed.
Scale Buildup in Older Pipes
Older cast iron sewer lines often develop heavy scale buildup.
As corrosion forms along the interior walls, the effective pipe diameter becomes smaller.
This creates rough surfaces that trap paper, grease, debris, and waste material.
Snaking may restore temporary flow while leaving most of the scale buildup behind.
When Hydro Jetting May Be the Better Solution
In situations involving grease, sludge, roots, scale, or years of accumulated buildup, hydro jetting may provide a more complete cleaning.
Hydro jetting uses high-pressure water to scour the interior walls of the pipe, helping remove material that traditional snaking may leave behind.
This often results in longer-lasting performance and fewer recurring clogs.

Real-World Example: Main Line Backup in Woodland
McKee Brothers Plumbing recently responded to a Woodland homeowner dealing with a severe sewer backup. Water was backing up into the shower and the toilet was no longer flushing properly.
Rather than simply running a snake through the line, our team performed a full hydro jet descaling service from the cleanout to the vent system.
The hydro jetting process removed heavy buildup, cleared debris, and restored proper flow throughout the sewer system.
Projects like this demonstrate why some recurring drain problems require more than basic snaking.

Could Your Sewer Line Be Damaged?
Sometimes recurring clogs are not caused by buildup at all.
A sewer camera inspection may reveal:
- Cracked sewer pipes
- Collapsed pipe sections
- Offset joints
- Root intrusion
- Pipe bellies
- Severe corrosion
In these situations, cleaning alone may not permanently solve the problem.
Repair or replacement may be necessary to eliminate the source of the recurring blockage.

How to Prevent Future Drain Clogs
While no drain system is completely maintenance-free, several practices can help reduce the likelihood of recurring clogs:
- Avoid pouring grease down drains
- Use drain strainers in sinks and showers
- Avoid flushing wipes and hygiene products
- Schedule professional inspections when problems begin appearing
- Address slow drains before complete blockages occur
- Consider hydro jetting for chronic buildup issues
What About Older Homes?
Many older homes throughout Woodland, Davis, Sacramento, and surrounding communities have aging plumbing systems that are more susceptible to recurring drain issues.
Cast iron, clay, Orangeburg, and older sewer materials often develop problems as they age.
If your home experiences frequent plumbing issues, there may be underlying infrastructure concerns that require professional evaluation.

Frequently Asked Questions
Why does my drain clog again after being snaked?
In many cases, a drain snake restores flow but does not remove all grease, sludge, scale, roots, or buildup inside the pipe. The remaining material can cause new clogs to develop.
Is hydro jetting better than drain snaking?
Neither method is always better. Drain snaking is effective for many localized clogs, while hydro jetting is often preferred when heavy buildup or recurring blockages are present.
Can tree roots cause recurring drain clogs?
Yes. Tree roots commonly invade sewer lines and create recurring blockages by catching debris flowing through the pipe.
Should I get a sewer camera inspection?
If recurring clogs continue after professional cleaning, a sewer camera inspection can help identify hidden pipe damage, roots, or structural issues.
How often should drains be professionally cleaned?
The answer depends on the age of the plumbing system, usage patterns, and whether recurring issues are present. Homes with chronic drain problems may benefit from periodic maintenance.
