How to Install and Maintain a Laundry Room Floor Drain

Introduction: A laundry room floor drain is a vital component that helps manage water spillage and drainage, ensuring your laundry area stays clean and dry. Whether you’re building a new laundry room or upgrading an existing one, installing and maintaining a floor drain is essential to prevent water damage and maintain a safe and efficient workspace. In this guide, we’ll walk you through the process of installing a laundry room floor drain and offer tips on its ongoing maintenance.

Installing a Laundry Room Floor Drain

Gather the Necessary Tools and Materials: Before you start the installation process, you’ll need a few essential tools and materials:

  • Floor drain kit
  • Pipe cutter
  • PVC pipes and fittings
  • PVC cement
  • Teflon tape
  • Level
  • Screwdriver
  • Hacksaw
  • Measuring tape
  • Wrench
  • Safety equipment (gloves, safety goggles)

Determine the Drain Location:

Select a suitable location for the floor drain. It should be positioned at the lowest point of the room to ensure proper drainage. Ensure the drain is placed near the washing machine and in a convenient spot to avoid unnecessary pipe extensions.

Cut the Floor Opening:

Use a pipe cutter to cut a hole in the floor at the chosen location. Ensure it’s large enough to accommodate the floor drain.

Install the Drain Flange:

Place the floor drain flange into the hole, making sure it sits level with the floor. Apply a layer of PVC cement around the flange’s edges and press it into place.

Assemble the Drain Pipe:

Measure the distance from the floor drain to the nearest sewer line or main drainage system. Cut a piece of PVC pipe to the required length using a hacksaw. Attach a trap to one end of the pipe, and a 90-degree PVC elbow to the other end. Make sure to use Teflon tape to seal the threaded connections.

Connect the Drain Pipe to the Flange:

Slide the trap end of the drain pipe into the floor drain flange. Ensure a secure fit. Use a wrench to tighten it in place.

Secure the Pipe to the Sewer Line:

If your laundry room is not directly above the sewer line, you may need to run the PVC pipe to the appropriate location. Connect the PVC pipe to the sewer line using a suitable fitting. Ensure proper alignment and use Teflon tape for threaded connections.

Test the Drain:

Pour a bucket of water into the drain to ensure it drains properly. Check for any leaks and make adjustments as needed.

Finish the Installation:

Once you’re satisfied with the drain’s performance, secure any exposed pipes to the wall or floor to prevent movement. Make sure to follow local building codes and regulations throughout the installation process.

Maintaining a Laundry Room Floor Drain

Regular Cleaning:

To ensure your laundry room floor drain functions optimally, regular cleaning is essential. Remove any lint, debris, and soap scum that may accumulate in the drain. Use a drain snake or a brush to clean out any blockages. Avoid using harsh chemicals, as they can damage the drain and sewer pipes.

Inspect for Clogs:

Regularly inspect the drain for clogs or slow drainage. If you notice slow drainage, it’s essential to address the issue promptly to prevent any potential backups or overflows.

Check for Leaks:

Inspect the area around the floor drain for any signs of leaks. A leak can cause water damage and mold growth if left unattended. If you notice any leaks, tighten connections or replace damaged pipes as needed.

Maintain the Trap:

The trap in the floor drain is designed to prevent sewer gas from entering your laundry room. Periodically check the trap for blockages and ensure it remains filled with water to create an effective seal.

Prevent Lint Buildup:

Lint from your washing machine can accumulate in the drain over time. Consider using a lint trap on your washing machine’s discharge hose to catch lint before it enters the drain system. Clean the lint trap regularly.

Test Drain Functionality: Periodically pour a bucket of water down the drain to ensure it drains smoothly. This can help identify any potential issues before they become major problems.

Schedule Professional Maintenance:

Consider having a professional plumber inspect your laundry room floor drain at least once a year. They can assess the condition of the drain and address any potential problems before they worsen.


Installing and maintaining a laundry room floor drain is essential for a clean, efficient, and safe laundry area. Proper installation will ensure effective water management, while regular maintenance will prevent clogs, leaks, and other potential issues. By following the steps outlined in this guide, you can enjoy a hassle-free laundry experience and extend the life of your laundry room floor drain.
