All of the dehumidifiers we tested feature an external drain port to which you can connect either an included plastic hose or a standard garden hose (or any other correctly sized hose for that matter). You might not think that you’re actually going to need to drain the dehumidifier you end up buying. You might be thinking that you’ll just empty the condensate collection bucket when it fills up, and that’s it, no problem right? Well, the truth is that you’ll be fine just emptying the dehumidifier’s collection bucket when it fills up. It works. It gets the job done.
However, we strongly advise you to at least consider gravity drainage, especially if your humidity problem is severe. We’ll give you two quick reasons why we make this recommendation.
#1 Bucket Size
You’d be surprised how quickly a large capacity dehumidifier can remove moisture from the air. The average 50 pint dehumidifier removes roughly 50 pints of moisture a day. The average condensate collection bucket on a 50 pint unit has a capacity of somewhere between 14 and 16 pints. You’re easily looking at removing the dehumidifier’s bucket, emptying, and replacing it up to 3 or 4 times per day. That’s quite a bit of work. Work that you won’t have to do if you drain your dehumidifier and let gravity do the work for you.
#2 Interrupted Operation
Remember, a dehumidifier will stop operating as soon as its bucket’s full. It won’t resume operation until after you’ve emptied the bucket and replaced it. As an example of why this is important, let’s say you need to leave your home to run some errands or go to work for the day. In this scenario you leave your dehumidifier running at home while you’re away. As soon as the dehumidifier’s bucket is full, it automatically shuts off. You come home after several hours of the dehumidifier not running because its bucket was full. You’re looking at hours, even half a day or a full day wasted in which the dehumidifier could have been dehumidifying but wasn’t because its bucket was full.
Now consider the alternative. You connect a drain hose to the back of the unit and drain it using gravity. You no longer need to empty the unit’s condensate collection bucket 3 or 4 times per day. You also don’t have to keep track of when the dehumidifier beeps to let you know its bucket is full.
