How should I drain water from a basement dehumidifier?
The simplist solution to dehumidifying in an area with no drain is to use a dehimidifier with a built in pump such as this one:



It has a long thin tube that can be routed to an area with a drain (such as a washing machine drainpipe) or to the outside (through a window frame or a very small hole drilled through the wall).  If to the outside, you need to direct it away from the foundation.

There are a few versions available and they tend to cost a good bit more than a simple tank type, but the convenience may make it worthwhile.

If you already have a good dehumidifier and don't want the expense of replacing it, you may be able to use an add-on dehumidifier pump such as this one



It is hooked up to the demidifier and then uses a thin tube to move the water in the same manner as a pumping dehumidifier.
