Is Your Laundry Drain Really Clogged?
Here’s how you know something’s wrong:
- The washer finishes, but the water just sits there.
- You hear gurgling or see water bubbling in the standpipe.
- Water leaks onto the floor during or after a wash cycle.
- A bad smell comes from the washer drain.
- The utility sink overflows during a rinse.
If you see one of these, stop using the washer. You’ve got a clog.
What Causes a Laundry Drain to Clog?
Let’s not overthink it. Most clogs fall into one of these buckets:
1. Lint
Even with a high-efficiency washer, lint gets in the drain pipes. It clumps over time and acts like a net. Hair, soap, and whatever else you wash gets stuck there.
2. Soap Scum
Some detergents and softeners leave a sticky coating inside your washing machine drain. Add hard water and it turns to sludge. It slows water down, then stops it.
3. Hard Water Deposits
Over time, minerals from hard water build up in pipes. This narrows the path and gives lint and sludge a place to grab on.
4. Foreign Objects
Small socks. Coins. Hair ties. If it fits through the washer, it can end up in your drain line.
5. Bad Pipe Setup
Some laundry rooms have tight bends or short standpipes. That setup makes it easy for clogs to form and hard for water to drain freely.
How to Fix a Clogged Laundry Drain
Start with the simple stuff. Only move to the next step if the clog doesn’t clear.
1. Unplug the Washer and Stop the Water
Don’t mess with clogs while the machine is powered. If water is flooding, turn off the supply valves.
2. Check the Drain Hose
- Pull it out of the standpipe.
- Look for kinks or clogs.
- Rinse it with a garden hose or wet/dry vac.
- If it looks old or worn, replace it.
3. Clean the Pump Filter
Some washers have a filter near the bottom. Open the access panel and check. Clean it if it’s full of lint or sludge.
4. Use Baking Soda and Vinegar
Pour half a cup of baking soda into the standpipe. Follow with a cup of vinegar. Let it bubble. After 10–15 minutes, flush with hot water.
5. Use a Drain Snake
If water still won’t go down, feed a drain snake into the pipe. Twist it slowly. If you feel resistance, work the snake back and forth to break the clog.
Don’t force it. If it won’t go in more than a few feet, you might have a deeper issue.
6. Try a Wet/Dry Vacuum
Seal the hose around the pipe. Set the vac to “suction” and let it run. It might pull the clog out if it’s close to the opening.
7. Skip the Chemical Drain Cleaners
Most are harsh on older pipes. They also don’t work well on lint or fabric-based clogs. If the drain is completely blocked, they’ll just sit in the pipe.
When to Call a Plumber
- Water backs up into your bathroom or kitchen sink.
- You’ve tried everything and nothing works.
- The clog keeps coming back.
- You hear strange sounds in other drains when the washer runs.
- The pipe smells like sewage.
These signs usually mean you have a blockage deeper in the line maybe even a sewer line problem.
How to Prevent Future Clogs
Install a Lint Trap
Clip one to the end of the drain hose. Replace it every month or two.
Flush the Drain Monthly
Monthly drain maintenance is important. Run hot water through the drain with vinegar or an enzyme cleaner. It keeps buildup from turning into a full clog.
Use Less Detergent
Too much soap leaves residue. Stick to the amount listed on the label.
Avoid Fabric Softener
Use white vinegar in the rinse cycle instead. It breaks down residue and softens clothes naturally.
Keep the Washer Clean
Run a cleaning cycle once a month. Check your manual for how.

FAQs
A clogged washer drain can feel like a mystery. Here are answers to the questions most people have.
How do I know if my laundry drain is clogged or slow?
If water pools in the washer or standpipe after a cycle, it’s clogged. If it drains slowly but doesn’t back up, it’s restricted but not fully blocked.
Can a clogged laundry drain affect other parts of the house?
Yes. If your washer drain ties into the main sewer line, a clog can cause water to back up into nearby sinks or tubs.
Is it safe to use boiling water to unclog the drain?
Use hot water, not boiling. Boiling water can damage PVC pipes.
What kind of drain cleaner is safe for washing machine drains?
Enzyme-based cleaners or vinegar and baking soda. Avoid chemical drain cleaners—they can be too harsh and don’t work well on fabric-based clogs.
How often should I clean the washer drain?
Once a month. Add it to your cleaning routine to avoid buildup.
Do drain snakes always work?
No. If the clog is too deep or packed in, you might need a plumber with a camera or hydro-jetting tools.
