Crawl space dehumidifier is made to control the humidity in a very tight space. This dehumidifier prevents mold, musty odors and mildew. They also stop wood from rotting or becoming a termite wet area. Crawl space dehumidifiers require no maintenance; there are no buckets to have to keep emptying. Their compact size and sturdy handles make for an easy install. They also lower your utility costs because they only run when it’s necessary. By replacing your crawl space dehumidifier, your indoor air quality is improved which ensures you that you and your family’s health is protected. Crawl space dehumidifiers are easy to replace. If you have ever installed a window air conditioner, replacing a crawl space dehumidifier should be a piece of cake. The tools and instructions you will need to complete this job are listed below.
Tools and Materials Needed:
- Replacement dehumidifier
- Wood or cement block
- Water hose
- Condensate pump
- Adjustable feet (optional, but may be needed)
Step 1 – Remove the Existing Crawl Space Dehumidifier
Unscrew the hose from the drain and remove the existing crawl space dehumidifier.
Step 2 – Setting Up the Replacement Crawl Space Dehumidifier
Place the new crawl space dehumidifier on a wood or cement block. The block is used to raise the dehumidifier up in order to let the water drain down through a hose. The dehumidifier can be leveled easily by using adjustable feet.
Step 3 – Creating a Drainage System (if you currently have one, skip this step)
Create a drainage system to allow water to drain away from the crawlspace. Using a regular water hose, screw the female end of the hose into the drain. Run the hose out from the crawlspace or attach it to a drain or a pump. The point is to have the water draining far from the crawlspace. Otherwise, the water will go back into the crawlspace. A condensate pump and longer tubing for draining may be necessary depending on your property logistics.
Step 4 – Connecting the Line through a Condensate Pump
Run the hose from the crawl space dehumidifier to the condensate pump. There should be no “slack” in the hose or flooding will occur. There should also be no part of the hose above the level of the dehumidifier as this will also flood the dehumidifier. The line should go from the condensate pump to the drain field. Whether you run the hose through the vent or the wall, the hole for the hose should be just large enough for the hose to fit through. Plug the condensate pump in a regular electrical outlet that is properly grounded.
Step 5 – Testing the Drainage System
Test the water drainage system when the dehumidifier has been set up. The HVAC system needs to be fully functional. After testing the HVAC system, test the water removal setup and all PVC hose and plastic pipe connections. This will confirm that there are no leaks coming from anywhere.
