How to Drain a Dehumidifier to the Outside

How to Drain a Dehumidifier to the Outside

Manual Method to Drain a Dehumidifier

It is as easy to do. If you have a dehumidifier that has a separable water bucket, you can remove the water bucket. Then you can either drain the water outside of your home or put it into the sink.

Automatic Method to Drain a Dehumidifier

There have three different automatic methods for draining a dehumidifier. Let’s give them a shot –

Drainage With an External Condensate Pump

If you want to drain a dehumidifier for crawl space or you do not have a floor drainage option, you should use an external condensate pump. Besides, when a gravity method does not work for draining water, you can follow this method. A condensate pump is a pump that collects condensate and disperses it through a pipe to the sink, outside, etc.

Here is the step by step guide:

  • Place the dehumidifier in a higher position like – chair, table, etc. You must keep it close to the condensate pump, otherwise, the hose can not reach the pump.
  • Connect one end of a hose to the drain port and the other end to the top connection of the condensate pump.
  • Take another small hose. Connect its one end to another connection of the condensate pump and another end to sink or wherever you want to drain water.
  • Turn on the condensate pump and dehumidifier at the same time. When the condensate pump will fill with water, it will automatically channel water through the small hose to the outside.

How Do You Get My Dehumidifier to Drain Through the Hose?

This method is also called the gravity method. Many dehumidifiers come with a built-in drain hose option. This method requires a floor draining option, and it works on gravity. If you do not have this option, you should choose the first option.

Here is the step by step guide:

  • As this method works on gravity, you should place the dehumidifier at a higher position (6 inches is great).
  • Connect one end of a garden hose to the drain port of the dehumidifier.
  • Place another end of this hose at your garden or house gutter.
  • You can also put the hose on your floor drain.
  • Run the dehumidifier and see there is any leak or not.

Keep the dehumidifier very close to your floor drain to see the optimum result.

Small note: You should maintain the dehumidifier position always higher than the drainage location.

Drainage With a Built-in Dehumidifier Pump

A built-in pump makes it easy to drain a dehumidifier without human touch. It can elevate water vertically up to 15 ft. But if you have already a dehumidifier without a built-in pump, you should follow the number one/two method. If you do not have a floor drainage option, you should choose the first method.

Here is the step by step guide:

  • Place the dehumidifier wherever you want. You can put it either in a higher position or in the basement.
  • Connect a hose to its drain port.
  • You can connect another end of the hose to the sink, drain hole, or outside of your house.
  • Run the dehumidifier.
  • The pump will collect the condensate and disperse it through the hose towards the outside of the house.
