If your drains keep clogging, there is usually a reason the blockage keeps coming back. Hair, grease, soap residue, food waste, foreign objects, or buildup inside the pipe can all create recurring clogs. When several drains are slow or clogged at the same time, the problem may be farther down the plumbing system.
A single slow drain may be something you can address with basic cleaning or a plunger. A drain that repeatedly backs up after you clear it, however, often needs professional attention.
For homeowners in Longview, TX, figuring out where the clog is occurring and what is causing it is the first step toward fixing the problem instead of temporarily clearing the symptoms.
Why Does the Same Drain Keep Clogging?
When the same sink, shower, tub, or toilet keeps clogging, something is probably continuing to restrict water flow inside that drain line.
Sometimes a plunger or drain snake creates a small opening through the blockage without completely removing it. Water begins flowing again, so the problem appears to be fixed. Over time, debris collects around the remaining buildup and the drain slows down again.
That is why a drain that clogs once is different from a drain that keeps clogging every few weeks or months.
Recurring clogs can be caused by:
- Hair buildup
- Soap residue
- Grease and cooking oil
- Food particles
- Too much toilet paper
- Items that should not have been flushed
- Mineral buildup
- A blockage deeper in the drain line
- Problems with the main sewer line
The location and behavior of the clog can provide important clues about its cause.
1. Hair Is Building Up in the Drain
Hair is one of the most common causes of clogged bathroom drains.
As hair enters a shower, bathtub, or bathroom sink drain, it can collect inside the pipe. Soap, shampoo residue, skin oils, and other debris can stick to the hair and gradually create a larger blockage.
At first, you may simply notice that the water takes a little longer to disappear.
As the clog grows, you may see:
- Water pooling around your feet in the shower
- A bathtub taking longer to drain
- A bathroom sink draining slowly
- Standing water after using the fixture
- A clog returning shortly after it was cleared
Drain screens or hair catchers can help reduce the amount of hair entering the plumbing, but an existing blockage may need to be physically removed.
2. Grease and Food Are Clogging the Kitchen Drain
Kitchen sinks deal with a different type of buildup.
Cooking grease, oils, fats, sauces, food particles, and other kitchen waste can collect inside drain pipes. Even substances that go down the drain as liquids can cool and stick to the inside of the plumbing.
Once a layer begins forming, additional food and debris can attach to it.
Over time, the inside diameter of the pipe becomes smaller and water has less room to pass through.
You may notice:
- A kitchen sink that drains slowly
- Water backing up into the second side of a double sink
- Gurgling after the sink drains
- A recurring kitchen sink clog
- Unpleasant odors from the drain
One of the best ways to prevent these clogs is to avoid putting fats, oils, grease, and large amounts of food waste down the kitchen drain.
Scrape food into the trash before washing dishes and dispose of cooking grease separately rather than pouring it into the sink.
3. Soap Residue Can Narrow Your Drain Pipes
Soap may seem harmless because it is designed to wash away with water, but residue can still contribute to drain buildup.
Certain soaps can combine with minerals in the water and other material inside the pipe. Hair, skin oils, toothpaste, shaving products, and dirt can then stick to that buildup.
This is particularly common in:
- Bathroom sinks
- Bathtubs
- Showers
A little residue does not create an immediate blockage. The problem develops gradually as layers accumulate.
If a drain becomes slower over several months rather than clogging suddenly, buildup inside the pipe may be responsible.
4. Something Went Down the Drain That Shouldn't Have
Plumbing drains are designed to carry wastewater and specific types of waste. Problems begin when other materials enter the system.
Toilets are particularly vulnerable.
As a general rule, the only things that should be flushed are human waste and toilet paper.
Items that commonly contribute to clogs include:
- Paper towels
- Facial tissues
- Baby wipes
- Cleaning wipes
- Feminine hygiene products
- Cotton swabs
- Dental floss
- Diapers
- Cat litter
- Excessive amounts of toilet paper
Even products marketed as flushable may not move through every plumbing system as easily as toilet paper.
Kitchen and bathroom sinks can also become clogged by objects that accidentally fall into the drain.
If the clog appeared suddenly after something unusual went down the fixture, an object lodged in the drain may be the cause.
5. You're Only Partially Clearing the Clog
One reason a drain keeps clogging is that the original blockage was never completely removed.
Imagine a drain pipe that is mostly blocked with buildup.
Using a plunger or small drain snake might create enough space for water to begin flowing through the center again. The drain seems fixed because the standing water disappears.
But much of the buildup may still be attached to the walls of the pipe.
Eventually, more material catches on that buildup and closes the opening again.
This is why homeowners can sometimes find themselves clearing the same sink or shower repeatedly.
If you're reaching for the plunger every few weeks, it may be time to have the drain cleaned more thoroughly.
6. Several Drains May Share the Same Problem
Pay attention to whether the problem involves one fixture or several.
If only one bathroom sink is slow while every other drain works normally, the blockage is probably relatively close to that fixture.
If the toilet, bathtub, and sink in the same bathroom are all having problems, the blockage may be farther along a drain line they share.
If drains throughout the house begin backing up or draining slowly, the problem could be even deeper in the plumbing system.
That distinction is useful because clearing an individual sink drain will not solve a blockage located somewhere else in the system.
7. The Main Sewer Line May Have a Blockage
Not every recurring drain problem originates inside the fixture itself.
Wastewater from the drains throughout your home eventually travels into a larger sewer line. If that line becomes restricted or damaged, multiple fixtures can begin showing symptoms.
Warning signs can include:
- Several slow drains at the same time
- Multiple fixtures backing up
- A toilet that gurgles when another fixture drains
- Water appearing in a tub or shower when a toilet is flushed
- Recurring clogs throughout the house
- Sewage odors
- Wastewater backing up into a low drain
A main-line problem is different from an ordinary clogged sink.
Richard Holt Plumbing can use camera inspection equipment when necessary to help determine what is happening inside a sewer line and locate a problem without automatically digging up the surrounding property.
Why Does My Toilet Keep Clogging?
A toilet that repeatedly clogs can have several possible causes.
Sometimes the problem is simply too much toilet paper or something being flushed that should not have gone down the drain.
If the toilet clogs during normal use, however, there may be a restriction in the toilet trap, drain line, or another part of the plumbing system.
Watch for other symptoms around the bathroom.
If the toilet clogs while the sink and shower drain normally, the issue may be isolated to the toilet.
If the toilet clogs while the bathtub also drains slowly or gurgles, there may be a shared drain-line problem.
Repeatedly plunging the toilet may restore flow temporarily, but frequent clogs are worth investigating.
Why Does My Shower Drain Keep Clogging?
Hair and soap buildup are two of the biggest reasons shower drains become clogged.
Because the buildup forms gradually, you may first notice that the shower takes longer to drain.
Eventually, water may begin collecting around your feet while you're showering.
A hair catcher can help prevent future problems, but it cannot remove buildup that is already deeper inside the drain.
If removing visible hair near the drain opening does not improve water flow, the restriction may be farther down the pipe.
Why Does My Kitchen Sink Keep Clogging?
When kitchen drains repeatedly clog, grease and food buildup are common suspects.
Grease is particularly troublesome because it can coat the inside of the pipe. Food particles and other debris can then become trapped in that sticky layer.
To help prevent kitchen drain clogs:
- Scrape dishes before rinsing them
- Keep cooking oil and grease out of the sink
- Avoid washing large amounts of food waste down the drain
- Use a sink strainer to catch larger particles
- Clean the strainer regularly
If the kitchen drain continues to clog despite changing these habits, existing buildup may need to be professionally removed.
Should You Use Chemical Drain Cleaner?
It can be tempting to reach for a bottle of chemical drain cleaner every time a sink becomes slow.
The problem is that chemical products do not necessarily remove the material causing a recurring clog. In some situations, they may create an opening through the blockage without fully clearing buildup from the pipe.
Some chemical drain cleaners also contain highly corrosive ingredients and need to be handled carefully.
For minor household clogs, a plunger or appropriate drain snake is often a better first step than repeatedly pouring chemicals into the plumbing.
If the drain continues to clog, professional drain cleaning can address the underlying obstruction rather than relying on repeated chemical treatments.
What Can I Try Before Calling a Plumber?
A simple clog does not always require professional service.
There are several basic steps homeowners can take first.
Remove Visible Debris
For sinks, tubs, and showers, check the drain opening for visible hair or debris.
Removing material near the surface may be enough to restore normal drainage.
Clean the Drain Stopper
Bathroom sink and tub stoppers often collect hair and soap residue.
Removing and cleaning the stopper can sometimes solve a slow drain before more extensive work is needed.
Try a Plunger
A plunger can help move a simple blockage.
Make sure you are using the appropriate type of plunger for the fixture and create a good seal around the drain opening.
Use a Basic Drain Snake Carefully
A small household drain snake may help retrieve hair or other material located near the fixture.
Do not force equipment farther into the plumbing if you encounter resistance or are unsure how the drain is configured.
Check Other Fixtures
This is one of the most useful troubleshooting steps.
Run water in nearby sinks, tubs, and showers and flush the toilets.
If only one fixture is affected, the clog is more likely to be local.
If several fixtures have problems, stop treating them as individual clogs. You may have a blockage farther down the plumbing system.
When Should You Call a Plumber for a Clogged Drain?
A plumber should inspect the problem when the clog is no longer a one-time inconvenience.
Consider scheduling professional drain cleaning if:
- The same drain keeps clogging
- A drain becomes slow again shortly after you clear it
- Several drains are slow at the same time
- Water backs up into another fixture
- Your toilet frequently clogs during normal use
- You hear gurgling from nearby drains
- You smell sewage from the plumbing
- A plunger or basic drain snake does not solve the problem
- You suspect something is lodged inside the pipe
- Wastewater is backing up into your home
The longer a significant blockage remains in the system, the greater the chance of wastewater overflowing from a sink, tub, shower, or toilet.
How Does Professional Drain Cleaning Help?
Professional drain cleaning is designed to identify and remove the blockage preventing wastewater from moving normally through the plumbing.
The appropriate approach depends on where the clog is located and what is causing it.
A plumber can determine whether the problem is located near an individual fixture or deeper within the drainage system.
For recurring or difficult problems, additional diagnostic equipment may be useful.
A camera inspection, for example, can allow a plumber to examine certain drain and sewer lines from the inside. This can help locate stubborn blockages and identify problems that would otherwise be difficult to see.
The goal is not simply to get water moving for the moment. It is to determine why the drain keeps clogging and choose the appropriate solution.
How Can You Prevent Drains From Clogging Again?
Good habits can reduce the amount of material entering your drain pipes.
In the Kitchen
- Keep fats, oils, and grease out of the sink
- Scrape food from dishes before washing them
- Use a sink strainer
- Empty the strainer into the trash
- Avoid putting fibrous or starchy food waste into the drain
In the Bathroom
- Use hair catchers in tubs and showers
- Clean drain stoppers regularly
- Remove visible hair before it enters the drain
- Keep cotton swabs, floss, and personal care products out of sinks and toilets
At the Toilet
Stick with the simplest rule: flush human waste and toilet paper.
Put wipes, paper towels, feminine products, cotton products, and other household waste in the trash.
Good prevention cannot correct an existing obstruction, but it can help reduce how quickly new buildup develops after the drain has been properly cleaned.

Frequently Asked Questions About Clogged Drains
Why does my drain keep clogging even after I unclog it?
The original clog may only have been partially cleared. Hair, grease, soap residue, food waste, or other buildup can remain attached to the inside of the pipe and quickly collect more debris. A recurring clog often needs more thorough drain cleaning.
What causes drains to clog most often?
Common causes include hair, soap residue, cooking grease, food particles, excessive toilet paper, wipes, foreign objects, and buildup inside the pipe. The likely cause depends partly on which fixture keeps clogging.
Why are multiple drains clogging at the same time?
When several fixtures become slow or clogged at the same time, they may share a blockage farther down the drainage system. If drains throughout the house are affected, a main sewer-line issue may need to be investigated.
Can pouring grease down the sink clog the drain?
Yes. Cooking fats, oils, and grease can contribute to buildup inside kitchen drain pipes. Other food particles can then stick to that buildup and gradually restrict water flow.
Is it safe to use chemical drain cleaner every time a drain clogs?
Repeatedly relying on chemical drain cleaners is not the best solution for a recurring clog. Some drain cleaners contain corrosive chemicals, and opening a small path through a blockage does not necessarily remove the underlying buildup. If the same problem keeps returning, professional drain cleaning may be more appropriate.
Why does my toilet gurgle when I run the sink or shower?
Gurgling can occur when air movement inside the drainage system is disrupted. When it happens along with slow drains, backups, or problems involving several fixtures, there may be a blockage or another drainage issue that needs professional inspection.
How do I know if a clog is in my drain or sewer line?
A clog affecting only one sink or shower is more likely to be located near that fixture. Multiple clogged drains, gurgling toilets, backups between fixtures, or wastewater appearing in a low drain may indicate a problem farther down the system.
When should I call a plumber for a clogged drain?
Call a plumber when the same clog repeatedly returns, multiple fixtures are affected, a plunger does not restore normal drainage, water backs up into other fixtures, or you notice sewage odors or wastewater backups.
Can a plumber see what is clogging a drain?
Depending on the location and type of plumbing line, a plumber may be able to use camera inspection equipment to examine the inside of the line. This can help locate certain blockages or identify other problems contributing to recurring drainage issues.
