How to Run a Washing Machine Drain Outside: A Step-By-Step Guide

Running a washing machine drain outside can be a practical solution for managing wastewater, especially in homes without a traditional plumbing setup. Whether you're installing a new washing machine in a laundry room, garage, or utility area, this guide will help you understand how to effectively and safely drain washing machine water outside.

Understanding the Basics

Why Drain Outside?

Draining a washing machine outside can be necessary in several situations:

• Inadequate Indoor Plumbing: Some homes, especially older ones or those in rural areas, may lack proper drainage for a washing machine.
• Temporary Installations: If you’re using a washing machine in a temporary setup, such as during renovations or in a workshop, outside drainage may be the most convenient option.
• Wastewater Management: Properly managing wastewater can help avoid plumbing issues, odors, and backups.

Considerations Before You Start

1. Local Regulations: Before installing any drainage system, check local plumbing codes and regulations. Disposing of wastewater improperly can lead to environmental hazards and legal repercussions.
2. Environmental Impact: Ensure that the area where the water will drain is suitable for absorbing and managing wastewater. Avoid areas prone to flooding or that may affect your property or neighbors.
3. Soil Absorption: If using a drainage pit or field, ensure the soil can absorb water effectively. Sandy or loamy soils typically work best, while clay soils may require additional measures to avoid pooling.

Tools and Materials Needed

Tools

• Adjustable Wrench: For tightening connections.
• Screwdriver: For securing fittings.
• Pipe Cutter or Hacksaw: To cut pipes or hoses as needed.
• Level: To ensure proper drainage slope.
• Bucket or Towel: To catch spills during installation.

Materials

• Drain Hose: Typically made of flexible rubber or plastic.
• PVC Pipe: For creating a more permanent drainage solution.
• Hose Clamps: To secure hose connections.
• Soil or Gravel: For drainage pits.
• Optional: A drainage pit or barrel for more efficient water management.

Step-by-Step Installation Process

Step 1: Prepare the Area

Clear the Space

Begin by ensuring the area around your washing machine is clear of debris and obstacles. This will give you the room needed for installation and access to the washing machine’s drain.

Assess Drainage Location

Choose a suitable location outside for the drainage. Ideally, this area should slope away from your home to prevent water from pooling near your foundation. Make sure it’s not near any vegetable gardens, water sources, or areas where pets frequent.

Step 2: Turn Off the Washing Machine

Ensure that the washing machine is turned off and unplugged. This is a crucial safety step to avoid accidents while you work.

Step 3: Locate the Drain Hose

Identify the Drain Hose

Locate the drain hose at the back of your washing machine. This hose typically connects to the household plumbing to carry wastewater away from the machine.

Step 4: Extend the Drain Hose

Measure the Distance

Measure the distance from the washing machine to your chosen drainage area. This will determine how much additional hose you may need.

Cut the Hose

If necessary, cut a length of new drain hose to extend the existing hose. Make sure it’s long enough to reach the drainage area without kinks.

Attach the Hose

Use hose clamps to secure the new hose to the existing drain hose. Make sure the connection is tight to prevent leaks.

Step 5: Install a Drainage Pit (Optional)

Dig a Hole

If you're opting for a drainage pit, dig a hole about 2-3 feet deep and wide enough to hold a barrel or to allow for gravel and soil.

Add Gravel

Place a layer of gravel at the bottom of the pit to help with drainage and prevent clogging. This will also facilitate the absorption of wastewater into the surrounding soil.

Position the Drain Hose

Insert the end of the drain hose into the pit, ensuring it’s positioned above the gravel layer to allow water to flow freely.

Step 6: Create a Surface Drainage System (Optional)

For a more organized drainage setup, you can use PVC pipes to direct the water.

Plan the Layout

Determine how you want the pipes to run from the washing machine to the drainage area. Ensure there is a clear path and that the slope will promote drainage.

Cut PVC Pipes

Using a pipe cutter, cut the necessary lengths of PVC pipe to create your drainage system.

Assemble the System

Connect the pipes using appropriate fittings, making sure that the pipes have a slight downward slope (at least 1/4 inch per foot) to facilitate proper drainage.

Secure the Pipes

Use pipe straps or brackets to secure the PVC pipes in place, ensuring they are stable and won’t move.

Step 7: Connect to the Washing Machine

Attach the Drain Hose

Connect the end of the drain hose (or the PVC pipe) back to the washing machine drain outlet. Ensure it is securely fastened and that the connection is tight.

Step 8: Test the System

Turn On the Washing Machine

Plug in the washing machine and run a short cycle to test the drainage system.

Monitor the Drainage

Observe the drainage area to ensure water flows properly and does not pool. If you notice any issues, adjust the hose or pipe to eliminate kinks or blockages.

Step 9: Adjust if Necessary

If you encounter any problems, such as slow drainage or pooling, make the necessary adjustments:

• Check Slope: Ensure that the hose or pipe has the correct slope for drainage.
• Inspect for Kinks: Look for any kinks or bends that might be obstructing water flow.
• Add More Gravel: If using a drainage pit, consider adding more gravel to enhance drainage.

Maintenance Tips

Once your washing machine is set up to drain outside, regular maintenance will ensure it operates efficiently and effectively:

1. Regular Inspections: Periodically check the drain hose and connections for wear and tear. Look for cracks or signs of leaks.
2. Clear Debris: Keep the drainage area clear of leaves, dirt, or other debris that might obstruct flow.
3. Monitor Soil Condition: Observe the surrounding soil for pooling. If it becomes saturated, consider creating a larger drainage area or additional drainage options.
4. Check Local Codes: Stay informed about any local regulations regarding wastewater disposal. Adjust your setup as necessary to comply with any changes.

Troubleshooting Common Issues

1. Pooling Water

If you notice water pooling around the drainage area:

• Inspect for Blockages: Ensure there are no clogs in the drain hose or PVC pipes.
• Adjust Slope: Make sure the drainage system has a proper slope away from the house.
• Consider a Larger Pit: If the current pit is too small, it may not handle the water volume effectively.

2. Slow Drainage

If water is draining slowly:

• Check for Kinks: Look for any bends in the hose that could restrict flow.
• Inspect Connections: Ensure all connections are tight and secure, as loose fittings can lead to slow drainage.
• Evaluate Soil Absorption: Test the soil for absorption. If it’s too compacted, consider aerating the area or adding organic material to improve drainage.

3. Bad Odors

If you notice unpleasant odors coming from the drainage area:

• Check for Standing Water: Ensure that water isn’t pooling, which can cause odors.
• Clean the Area: Remove any debris or organic material that may be decomposing and causing smells.
• Use Enzyme Cleaners: Consider using enzyme cleaners that break down organic matter and eliminate odors.

Environmental Considerations

When draining wastewater outside, it’s crucial to consider the potential impact on the environment. Here are some guidelines to ensure you’re doing it responsibly:

1. Avoid Polluting Water Sources: Ensure that wastewater does not drain directly into streams, lakes, or other bodies of water without proper treatment.
2. Use Eco-Friendly Detergents: Opt for biodegradable and environmentally friendly laundry detergents to minimize the impact on soil and groundwater.
3. Regularly Maintain Your System: Keeping the drainage system in good condition helps prevent leaks and reduces the risk of contaminants entering the soil.

Conclusion

Running a washing machine drain outside can be an effective solution for managing wastewater when traditional plumbing isn’t available. By following this comprehensive guide, you can safely install and maintain your washing machine drainage system, ensuring efficient operation and compliance with local regulations.

Remember to always check your local codes before beginning the installation, and don’t hesitate to consult a professional plumber if you have any concerns or questions about your specific situation. With the right approach, you can enjoy the convenience of a washing machine while managing wastewater responsibly.
