Can You Drain the Dehumidifier in The Crawl Space?

A common question we get here at Crawl Space Solutions is whether or not it’s okay to drain the dehumidifier in the crawl space. After all, the dehumidifier is there to help remove moisture from the air, so it stands to reason that draining it would just put more moisture back into the space.

However, there are a few things to remember before you decide to drain your dehumidifier. First of all, if your unit is equipped with an automatic shut-off feature, it’s important to know that this feature may not work properly if the unit is constantly being drained.

Additionally, if you have a designated drainage area for your unit, draining it into it will help prevent any water damage that could occur if the unit were to overflow.

In short, while some potential risks are involved with draining a dehumidifier in the crawl space, these risks are typically outweighed by the benefits of doing so. Taking a few precautions can help ensure that your unit continues to work effectively and that your crawl space remains dry and comfortable.

3. Reduces Allergens in the Air

Another benefit of a drain dehumidifier is that it can help to reduce allergens in the air. Allergens are particles that can cause an allergic reaction in some people, leading to symptoms such as sneezing, coughing, and watery eyes.

Dust mites are one type of allergen that thrive in humid environments. By reducing the humidity levels in your crawl space with a drain dehumidifier, you can help reduce the number of dust mites in the air and potentially alleviate allergy symptoms.

4. Creates a Healthier Environment

A drain dehumidifier can also help create a healthier environment by reducing mold spores, dust mites, and other allergens in the air. This can lead to improved air quality and may even help to reduce respiratory problems such as asthma.

Suppose you or someone in your family suffers from allergies or asthma. In that case, a drain dehumidifier may be able to provide some relief by creating a healthier environment for them to live in.

5. Protects Your Home from Water Damage

Finally, a drain dehumidifier can also help to protect your home from water damage. Water damage can occur when water seeps into cracks or holes in your foundation or walls and begins to break down the structure of your home.

This can lead to serious repairs being needed and may even make your home uninhabitable if left unchecked. A drain dehumidifier will help to keep your crawl space dry and free from water, which will ultimately help to protect your home from water damage.
