How to Connect a Dehumidifier Drain Hose
Should your home require a dehumidifier, you may not run it as often as you should because of the need to care for the dehumidifier drain. Connecting a drain hose eliminates the need to continually drain the water pail. By ‘porting’ the water directly from the drain bucket, the extra work is eliminated. It is important that you follow the manufacturer’s directions for proper placement of the dehumidifier. Also, remember to keep all doors closed to the room being dehumidified.
Tools & Materials
Step 1 - Determine Water Flow
- Garden hose
- Teflon tape
- Condensate Pump (Optional)
- Concrete block (Optional)
- Small level
In most cases, you can set the dehumidifier on some sort of pedestal (concrete block, etc.) close enough to a floor drain or a sink to allow for easy gravity flow. If, however, there is a not a drain to run the condensate hose to directly, you will need to add a condensate pump to the flow line for dehumidifier drain. In either case, locate the hose connector on the dehumidifier’s water bucket. Wrap the threads of the connector with Teflon tape. Wrap in a clockwise direction so that when you tighten the hose onto the threads, the tape will sink into the threads. To set the elevation to achieve gravity flow, fill the bucket with water, and raise the dehumidifier until the water flows from the hose.
Step 2 - Determine Placement of Dehumidifier
Be sure that the air discharge is not blocked. If your unit has a top airflow, you can position it close to a wall. Otherwise, you must follow manufacturer’s warnings and specifications for placement. Also, it is important that the water not be dispensed near electrical cords or outlets. It is essential that you set your dehumidifier drain to achieve gravity flow. This may take a little trial and error to get the elevation perfect. Achieving gravity flow of the water exiting the dehumidifier is necessary to keep the water from flowing back into the water collection bucket. You can use a concrete block or perhaps even build a shelf to hold the dehumidifier. Place a small level on top of the dehumidifier, and using the adjustable feet, make certain that the unit is level. When the elevation is correct, the water will run freely from the hose.
Step 3 - Extending Hose
If you do not have a floor drain close to where you need to place the dehumidifier, you will need to add a condensate pump to the dehumidifier drain line. The set-up is identical, just connect the opposite end of the hose to the pump, and then attach another hose to the pump outlet. Connect the second hose in the same manner as the first, wrapping Teflon tape in a clockwise direction around the threads. Run the pump outlet hose to the dehumidifier drain. There are also units available with internal condensate pumps, but they are considered more for commercial applications and are much more expensive than a residential unit.
