Best Hose for Dehumidifier

Dehumidifiers are often the best solution against excess moisture in your home. If left unattended for long, high humidity levels pose serious risks to your health and everyone at home. It can also lead to damage to structures, furniture, and other belongings. Effective humidity control in highly humid regions requires high-capacity dehumidifiers.

Dehumidifiers use various moisture removal methods to reduce humidity levels and in result, they usually produce water from the moisture collected in 24 hours. You can always empty the water by hand but this can be inconvenient for some. The good news is that most residential dehumidifiers offer an option for automatic draining through a hose. However, this drain hose is usually not included with the dehumidifier. In most cases, a standard garden hose works for portable dehumidifiers. 

If you want to use your dehumidifier’s gravity drainage functionality, you can choose from the following dehumidifier drain hoses with different lengths and diameters suitable for most dehumidifiers.

Draining Options of a Dehumidifiers

Most portable dehumidifiers used in the house have an internal water bucket to hold the collected moisture. Depending on the capacity of the dehumidifier to remove moisture, as well as the dampness levels of the particular room, manual drainage of the tank may be the most straightforward but usually not the most convenient draining option. 

The tank capacity varies depending on the brand and model. A larger size dehumidifier typically has a higher tank capacity than a smaller unit within the same brand but using the biggest dehumidifier isn’t usually the answer. If you want your dehumidifier to run with less downtime, you might need to empty the tank multiple times a day. Most dehumidifiers have auto shutoff to automatically turn off the unit when the tank is full to prevent water overflow. You need to empty the tank before the unit can resume operation.

Dehumidifier Drain Hose

While it’s an easy enough task in itself, not everyone has the time to check their dehumidifiers, remove the tank and empty the water more than once a day. If this is inconvenient for you, then you need a good dehumidifier hose for automatic gravity drainage. This is the most common option for portable dehumidifiers but some high-capacity units may also include a built-in condensate pump. 

Condensate Pump

Condensate Pump

A pump can push the water out up to a certain height so you need not worry about your dehumidifier’s placement with respect to the drain. Most condensate pumps can push water up to 15 feet above the unit. You can have the hose run up into a sink, out of a window or door or any other suitable location.

Dehumidifiers with a built-in pump also include a hose you can attach to the outlet before activating the pump function. Note that this is different from the drain hose you need for gravity drainage. If you’re using an industrial dehumidifier for crawl spaces, most models include a drain hose for gravity draining and some include an internal condensate pump. For dehumidifiers that don’t include a pump, you can also purchase an external condensate pump. learn more about the different draining options for dehumidifiers here.

How to Drain a Dehumidifier Automatically with Drain Hose

If you’re using your dehumidifier in home basements or any humid large rooms that you don’t frequently visit, that’s all the more reason you need a drain hose for automatic drainage. 

Some brands include a drain hose with your purchase, making the choice easier for you. To enable gravity drainage, just connect the hose to the dehumidifier outlet, usually located at the back or on the side of the unit. First, unscrew the drain plug or cap then attach the hose securely to the outlet. Some units include an adapter to attach the hose, others may require you to remove the water tank first and reach from below the unit to secure the hose connection.

Once attached, point the hose down towards the drain without any kinks or knots that can disrupt the water flow. Most people use a floor drain for this, but you can also use a sink or any drain you can access that is lower than the unit.

Dehumidifier Automatically with Drain Hose

Can You Use a Garden Hose for a Dehumidifier?

Most dehumidifiers come with a threaded drain outlet, sometimes with an adapter, with an opening approximately an inch wide or smaller. While a few brands offer PVC tubing specifically for dehumidifier draining, most dehumidifiers fit with a standard garden hose with ⅝ to ¾ inch diameter. This way, you can choose the length of the hose based on your needs as long as it satisfies the dehumidifier’s requirements. You can also use PVC pipe to attach to the hose adapter and make a 90-degree bend with the piping to funnel the water directly down the drain.

A few dehumidifier brands may also offer a separate drain hose compatible with its dehumidifier units, like the Frigidaire drain hose above. For example, this Santa Fe replacement drain hose for its high-capacity commercial dehumidifiers for crawl space.

Things to Consider When Using Gravity Drainage

When using a drain hose, always remember that you rely on gravity for it to work. Make sure the dehumidifier is on a flat, steady surface to avoid leaks from the tank or other places. 

If the ground is uneven, you can raise the dehumidifier with pieces of wood, metal, or dehumidifier risers. You can even hang the unit if your dehumidifier allows it, to securely place the unit on a level above the drain.

The drain must always be lower than the dehumidifier. Direct the drain hose downwards without kinks or knots, or any obstructions. If you don’t have a floor drain in the room, you can place a dehumidifier (if it’s small enough) on top of a counter to drain the water into a sink.

Tips in Maintaining your Dehumidifier

To make draining more convenient, it’s essential that you use the right dehumidifier for your space. This includes choosing the right type and size based on your room’s requirements. Once you have the correct dehumidifier, find the best location for it and make sure to place it on a level surface. Provide the required distance from walls, furniture, or other items that may disrupt the airflow or block the hose to maintain quiet operation.

Most dehumidifiers require little to no maintenance, but you must still keep it clean at all times. If you notice dust or grime collecting on the exterior of the unit, simply wipe it down with a dry cloth or use a damp rag for dirtier surfaces. Do not spray water or cleaning solvents directly on the unit unless instructed by the manual. Also remember to check the washable filter and clean or replace it if necessary. Check your manual for more specific cleaning and maintenance instructions.

If you’re using the collection bucket for draining, remember to dump the water as soon as possible to prevent mold and bacteria from growing inside. Disinfect it with liquid soap or white vinegar then rinse and dry before reinstalling.

If you’re using a drain hose, also check the tank in case some water has dripped into it. Wash the hose with the same solution of water and soap or vinegar. Pour the solution into one end and let it flush through the entire length of the hose. When not in use, make sure to dry and store the drain hose properly.

If you notice any leaks from your dehumidifier, inspect the hose attachment and make sure it’s secured. If there is no problem with the hose itself, check the dehumidifier’s tank, then the coils. While most dehumidifiers have auto defrost to prevent ice buildup, check the coils regularly when temperatures are low. If you still can’t find the cause of leaking, get the unit examined by an expert.

These are only some basic tips that can help keep your unit functioning and draining properly for a long time. If you have specific concerns, check your unit’s manual.


Dehumidifiers today feature intelligent control that can remove gallons of excess moisture daily from high-humidity areas. They produce condensate which usually collects in a built-in water tank. If you don’t have the time or simply don’t want to empty this water by hand, you can opt for a dehumidifier with continuous draining function. 

Most portable dehumidifiers give you an option to drain the condensate through a hose. A few brands include this drain hose, but usually all you need is a standard garden hose. Make sure to check the requirements for each specific model, including the length of the hose and the diameter of the openings. In most cases, you can also use this garden hose for many different purposes throughout your household.
