Is your washing machine backing up or draining slowly? You’re not alone—over 20% of U.S. homeowners report laundry-related plumbing issues each year, according to the American Housing Survey. A clogged washing machine drain pipe is a common but fixable problem, and learning how to use a plumbing snake on a washing machine drainage pipe can save you time, money, and the hassle of calling a plumber. In this guide, we’ll walk you through everything you need to know—safely and effectively.
Why Does a Washing Machine Drain Pipe Get Clogged?
Before snaking your drain, it helps to understand why clogs happen. Washing machines push out large volumes of water mixed with lint, soap residue, hair, and even small debris from clothes. Over time, these materials build up inside the drain pipe—especially if you use excessive detergent or have hard water.
According to the International Association of Certified Home Inspectors (InterNACHI), most washing machine drain clogs occur within the first 3–5 feet of the pipe, often near the P-trap or where the hose connects to the main drain.
What Is a Plumbing Snake (and Do You Need One)?
A plumbing snake (also called a drain auger) is a flexible, coiled metal tool designed to break up or retrieve blockages deep inside pipes. There are two main types:
Hand-crank augers: Ideal for shallow clogs (up to 25 feet). Affordable and easy to use.
Motorized drain snakes: Best for stubborn or deep clogs, but overkill for most washing machine issues.
For washing machine drains, a 25-foot hand-crank auger is usually sufficient—and far safer than chemical drain cleaners, which can damage PVC pipes and harm the environment.
💡 Pro Tip: Never use a toilet auger (closet auger) on a washing machine drain—it’s too short and not designed for sink-style pipes.
Step-by-Step: How to Use a Plumbing Snake on a Washing Machine Drain Pipe
Follow these steps carefully to avoid damaging your pipes or appliance.
Step 1: Turn Off Power & Water Supply
Unplug the washing machine.
Shut off the hot and cold water valves behind the unit.
Place towels on the floor to catch spills.
Step 2: Disconnect the Drain Hose
Locate the drain hose (usually a large gray or black tube connected to a standpipe or wall).
Loosen the clamp securing it to the standpipe.
Carefully pull it free—expect some residual water to drip out.
⚠️ Caution: If water gushes out when you disconnect the hose, the clog is likely in the standpipe, not the machine itself.
Step 3: Insert the Plumbing Snake
Feed the auger cable into the standpipe opening (not the hose!).
Rotate the handle clockwise as you push gently forward.
When you feel resistance, continue cranking—this is likely the clog.
Step 4: Break Up or Retrieve the Clog
Push and twist for 10–15 seconds once you hit resistance.
Slowly retract the snake. You may see lint, hair, or gunk wrapped around the tip.
Wipe it clean with an old rag.
Step 5: Flush the Drain
Pour 2 liters of warm water (22–28°C / 72–82°F) down the standpipe to test flow.
If it drains quickly, the clog is gone!
Reconnect the drain hose securely.
Step 6: Test the Washing Machine
Restore power and water.
Run a short rinse cycle to confirm proper drainage.
📌 Note: If water still backs up, the clog may be deeper in your home’s main sewer line. In that case, consult a licensed plumber.

The average cost for a plumber to clear a laundry drain is $150–$300, per HomeAdvisor (2025 data)—but preventable with regular maintenance.
Preventing Future Clogs: 4 Smart Habits
Use mesh lint traps on your washing machine hose ($5 on Amazon).
Switch to high-efficiency (HE) detergent—less residue buildup.
Flush the drain monthly with hot water and ½ cup baking soda + 1 cup vinegar.
Inspect hoses every 6 months for kinks or cracks.
These habits can extend your plumbing’s life by 5–10 years, according to the Plumbing-Heating-Cooling Contractors Association (PHCC).
FAQ Section
Q1: Can I use a drain snake on a washing machine without removing the hose?
A: Technically yes—but it’s far less effective. The hose often curves or has narrow sections that block the snake. For best results, disconnect the hose and snake directly into the standpipe.
Q2: How long should my plumbing snake be for a washing machine drain?
A: A 25-foot hand auger is ideal. Most clogs occur within 3–10 feet, but extra length gives you flexibility if the blockage is deeper.
Q3: What if snaking doesn’t work?
A: Try a wet/dry vacuum to suction the clog, or remove the P-trap under the sink (if your washer drains there). If those fail, the issue may be in the main sewer line—call a plumber.
Q4: Is it safe to snake a PVC pipe?
A: Yes—if you use gentle pressure. PVC is durable but can crack if you force a stiff or oversized auger. Stick to cables ≤¼ inch thick for residential drains.
Q5: How often should I clean my washing machine drain?
A: Every 3–6 months for prevention. Homes with pets, large families, or frequent laundry loads should lean toward the 3-month mark.
Q6: Can I rent a plumbing snake instead of buying one?
A: Absolutely! Most hardware stores (like Home Depot or Lowe’s) rent hand augers for $10–$20/day. Buying one costs $25–$50 and pays for itself after 2–3 uses.
Conclusion
Knowing how to use a plumbing snake on a washing machine drainage pipe empowers you to solve one of the most frustrating (but common) laundry room emergencies—fast, affordably, and without harsh chemicals. With just 30 minutes and basic tools, you can restore full drainage and avoid costly service calls.
