How to Install a Dehumidifier Pump

Why Install a Dehumidifier Pump?

Installing a dehumidifier pump is a smart solution for homes where gravity drainage isn’t possible. A dehumidifier pump actively removes condensate water from the unit, preventing water damage and ensuring the dehumidifier operates efficiently. This is especially important in basements, crawl spaces, or attics where the dehumidifier is located below the level of the drain.

Tools and Materials Needed

Before starting the installation, gather the following tools and materials:

• Dehumidifier pump
• Clear plastic tubing
• PVC pipe and assorted fittings
• Brass barbed fitting
• PVC primer and cement
• Pipe clip with 1-inch screws
• Stainless steel hose clamp
• Drill and drill bits
• Screwdriver
• Measuring tape
• Utility knife
• Safety goggles
• Gloves

Step-by-Step Installation Guide

1. Prepare the Work Area

Ensure the area around the dehumidifier is clean and dry. Turn off the dehumidifier and unplug it from the power source. This is a crucial safety step to prevent electrical hazards.

2. Position the Dehumidifier Pump

Place the dehumidifier pump near the dehumidifier, ensuring it is on a level surface. The pump should be within easy reach of the dehumidifier’s drain port and the chosen discharge point.

3. Connect the Drain Hose

Attach a clear plastic tubing to the dehumidifier’s drain port. Use a stainless steel hose clamp to secure the tubing and prevent leaks. Ensure the tubing is long enough to reach the pump’s inlet.

4. Install the Pump

Connect the other end of the tubing to the pump’s inlet. Use a brass barbed fitting if necessary to ensure a tight seal. Secure the pump to the wall or floor using the provided mounting hardware.

5. Run the Discharge Line

Attach a PVC pipe to the pump’s outlet. Use PVC primer and cement to secure the fittings. Run the PVC pipe to the desired discharge point, such as a floor drain, sump pump, or outside the house. Ensure the pipe has a slight downward slope to facilitate proper drainage.

6. Secure the Pipes

Use pipe clips to secure the PVC pipe to the wall or floor at regular intervals. This prevents the pipe from sagging and ensures a smooth flow of water.

7. Test the System

Plug in the dehumidifier and turn it on. Check for any leaks at the connections and ensure the pump is operating correctly. The pump should activate when the water level in the dehumidifier reaches a certain point.

Safety Tips

• Always turn off and unplug the dehumidifier before starting any work.
• Wear safety goggles and gloves to protect yourself from sharp edges and chemicals.
• Ensure all connections are tight and secure to prevent leaks.
• Regularly check the pump and drain lines for clogs or damage.

Troubleshooting Common Issues

• Pump Not Activating: Check the power supply and ensure the pump is properly connected. Inspect the float switch for obstructions.
• Leaks at Connections: Tighten all fittings and replace any damaged tubing or clamps.
• Clogged Drain Line: Clean the drain line and check for blockages. Use a plumber’s snake if necessary.
• Excessive Noise: Ensure the pump is securely mounted and the pipes are properly supported.
