A Step-by-Step Guide to Installing a Dehumidifier Pump


Are you tired of dealing with excess moisture in your home? Is your dehumidifier constantly filling up and needing to be emptied? If so, then installing a dehumidifier pump may be the solution you’ve been looking for. This blog post will provide a step-by-step guide on installing a dehumidifier pump using valuable tips.

Why Install a Dehumidifier Pump?

Excess humidity in your home can lead to various issues, including mold and mildew growth, musty odors, and damage to your furniture and belongings. While dehumidifiers are highly effective in removing moisture from the air, they can quickly fill up and require frequent emptying. By installing a dehumidifier pump, you can divert the collected water directly to a drain, eliminating the hassle of constantly emptying the tank.


Understanding the Functionality of the Dehumidifier Pump

The dehumidifier pump ensures continuous water removal, preventing stagnant water accumulation and mold growth. Additionally, it allows for the dehumidifier to be conveniently operated in basements, crawl spaces, or areas where a gravity drain is not feasible. Understanding the functionality of the dehumidifier pump enables users to effectively manage humidity levels in their living or working spaces, promoting a healthier and more comfortable environment.


Materials and Tools Needed

Before you get started, make sure you have the following materials and tools on hand:

  1. Dehumidifier pump
  2. Clear plastic tubing
  3. PVC pipe and fittings
  4. Brass barbed fitting
  5. PVC primer and cement
  6. Pipe clip with 1-inch screws
  7. Stainless steel hose clamp
  8. PVC pipe cutter
  9. Screwdriver

Step 1: Understanding the Functionality of the Dehumidifier Pump

Investigate how the dehumidifier pump works and where the water goes once pumped out.

Step 2: Gathering the Necessary Materials and Tools

Now that you understand the importance of a dehumidifier pump, it’s time to gather the necessary materials and tools. Head to your local hardware store or Amazon and look for the items mentioned in the shopping list above.

Step 3: Connecting the PVC Pipe to the Existing Pump

Using a PVC pipe cutter, cut a section of PVC pipe that will connect the dehumidifier pump to the existing pump. Ensure that the cut is clean and precise for a snug fit.

Step 4: Gluing the Pipes Together for a Secure Connection

To create a secure connection between the two pipes, apply PVC primer and cement to the ends of the PVC pipes. Push the pipes together firmly, ensuring that they are correctly aligned.

Step 5: Attaching the New Hose

Next, attach the clear plastic tubing to the dehumidifier pump using a stainless steel hose clamp. Tighten the clamp to ensure a leak-free connection.

Step 6: Testing the Pump

With the installation complete, it’s time to test the dehumidifier pump. Plug the pump into a ground fault circuit interrupter (GFCI) outlet, essential for safety when working with water. Pour water into the dehumidifier tank and check to see if the pump successfully removes the water and directs it to the drain.



Installing a dehumidifier pump can significantly improve the functionality and efficiency of your dehumidifier. Following a step-by-step guide, you can easily install a dehumidifier pump in your home and say goodbye to the inconvenience of constantly emptying the tank.

A dehumidifier pump works by automatically pumping the collected water to a drain or sink, eliminating manual emptying. This is especially useful if you have a large area that requires continuous dehumidifying or if you are not always home to empty the tank regularly.

To install a dehumidifier pump, you must gather the necessary tools and materials, including a compatible pump, tubing, and a nearby drain or sink. It’s important to carefully read the instructions provided with the pump and follow the recommended installation steps to ensure optimal performance.

Once installed, a dehumidifier pump can help maintain a consistent humidity level in your home, prevent mold and mildew growth, and improve the overall air quality. With the added convenience of automatic drainage, you can enjoy the benefits of a dehumidifier without the hassle of constantly tending to the water collection tank.

Overall, installing a dehumidifier pump can make a big difference in the functionality and convenience of your dehumidifier, providing a hassle-free solution for maintaining a comfortable and healthy indoor environment.
