Most homeowners deal with a clogged drain at some point. Whether it’s a slow bathroom sink, a kitchen drain that won’t empty, or a shower filling with water around your feet, drain clogs are one of the most common plumbing problems we see.
The good news is that many clogs can be prevented, and not every slow drain means you have a major plumbing problem.
Understanding what’s causing the clog is the first step toward finding the right solution, and preventing it from happening again.
What’s Causing Your Drain to Clog?
Different drains clog for different reasons.
Knowing which fixture is affected often provides clues about what’s happening inside the pipe.
Kitchen Sink Drains
Kitchen drains usually clog because of grease, food particles, and soap residue.
While hot water may seem to wash grease away, it often cools farther down the drain line and hardens along the inside of the pipe. Over time, that buildup narrows the pipe until food particles begin catching on it, eventually creating a blockage.
Some common items that should never go down your kitchen drain include:
- Grease or cooking oil
- Coffee grounds
- Pasta or rice
- Eggshells
- Fibrous vegetables like celery
- Large amounts of food scraps
Even homes with garbage disposals can experience clogs if too much food waste enters the drain.
Bathroom Sink Drains
Bathroom sinks typically clog because of:
- Toothpaste
- Soap residue
- Hair
- Makeup
- Shaving debris
These materials combine into a sticky buildup that slowly restricts water flow.
Shower and Tub Drains
Hair is by far the most common culprit.
Hair combines with soap residue to create stubborn clogs that gradually worsen over time.
Drain strainers can dramatically reduce the amount of hair entering the drain and are one of the simplest ways to prevent future clogs.
Laundry Drains
Laundry drains collect:
- Lint
- Hair
- Soap residue
Modern washing machines also discharge water very quickly, which can expose existing drainage problems that weren’t noticeable before.
Why Does the Same Drain Keep Clogging?
An occasional clog isn’t unusual.
But if you’re clearing the same drain every few months, there’s often an underlying problem.
Some of the more common causes include:
- Grease buildup that was only partially removed
- Corroded or rough interior pipe surfaces
- Older galvanized piping
- Poor pipe slope
- Long horizontal drain runs
- Undersized drain piping
Sometimes the clog isn’t the real problem, the plumbing system itself may be contributing to recurring backups.
At Lohmeyer Plumbing, we don’t just clear the clog and leave. If a drain keeps backing up, we’ll help you understand why so you can decide whether a longer-term solution makes sense.
Should You Use Chemical Drain Cleaners?
In most cases, we don’t recommend them.
Many store-bought drain cleaners use harsh chemicals that generate heat to break down clogs. While they occasionally provide temporary relief, they can also:
- Damage certain types of piping
- Harm sink finishes
- Create safety hazards if additional work is needed later
- Leave standing chemicals in the drain for anyone working on it
If you’ve already used a chemical drain cleaner before calling us, that’s okay, just let us know so our technician can take the proper safety precautions.
Can Bio-Clean Help?
For many homes, yes.
Bio-Clean uses naturally occurring bacteria and enzymes to break down the organic buildup that accumulates inside drain lines over time.
It works especially well for:
- Kitchen sink drains
- Bathroom sink drains
- Laundry drains
Bio-Clean isn’t designed to remove large blockages or recover lost jewelry, but it can be an excellent maintenance product for helping keep drains flowing freely.
When Is It Time to Call a Plumber?
It’s usually time to call if:
- The same drain keeps clogging.
- Water drains very slowly.
- Multiple attempts with a plunger haven’t worked.
- Water backs up into another fixture.
- You notice foul odors coming from the drain.
Professional equipment can often remove clogs that household plungers and small hand snakes simply can’t reach.
Could It Actually Be a Sewer Line Problem?
If only one drain is clogged, the problem is usually isolated to that fixture.
However, if several drains begin backing up at the same time, or flushing a toilet causes water to appear in a nearby shower or floor drain, the problem may actually be your home’s main sewer line.
In that case, clearing an individual drain won’t solve the issue.
Preventing Future Drain Clogs
A few simple habits can go a long way toward preventing future drain problems.
- Avoid pouring grease down the kitchen sink.
- Use drain strainers in showers and tubs.
- Only flush toilet paper.
- Don’t overload garbage disposals.
- Periodically use a maintenance product like Bio-Clean if recommended for your plumbing system.
Preventive maintenance is almost always easier, and less expensive, than dealing with a completely blocked drain.
The Bottom Line
Most drain clogs are caused by everyday buildup that develops gradually over time. While many can be cleared relatively easily, recurring clogs often point to a larger issue that’s worth investigating.
At Lohmeyer Plumbing, our goal isn’t simply to get the water draining again. We want to help you understand what caused the clog in the first place so you can avoid dealing with the same problem again.
Whether your drain needs a simple cleaning or a more permanent solution, we’ll explain your options and help you choose the approach that makes the most sense for your home.
