Dehumidifier – auto drain

Toolsguy | Posted in General Discussion on June 23, 2003 09:52am

Hi everyone, hope this isnt a dumb question but her goes. I have dehumidifier in the basement that pretty much runs the majority of the time. Instead of using the tank it comes with I would much prefer to have it pump the water out of the house.

Question #1 Are there mini pumps I can hook up to the tank so that when it gets to a certain level it pumps it out.?

Question #2: How do I feed the tubing up and out of the house? Drill a hole in the wall/ Siding and seal with sylicone? Would this hole lead to problems?

    Why not just run a drain hose to the floor drain or sump well?

      I have neither in this basement. Other than running the house out under the garage door but that wouldnt let the door come down all the way.

      Maybe up into the drain that the clothes washer uses?

        Hmmm...no floor drain or sump well, just a smooth floor with nothing? I guess you'll have to run the hose to the laundry tub, but the de-humidifier will have to be higher than the tub. Maybe put it on a strong shelf, nothing says it has to be floor level.

          I just did this last weekend. . .built a 4' stand, put the dehumid. on it with a garden hose running to the tub.  Gravity takes care of the water flow and no pumps to worry about.  If the pump stops working, the hose will fill and then start dripping on the floor.  If gravity stops working, there are more important things to worry about than the duhimid. draining! - Jason

            True. Thanks.

            And if the gravity solution is not a viable option (still my first choice too), the pumps work quite well, just like a tiny sump pump.

            Gravity is nice to have, because it won't wear out or cost money to run, but old basements don't always have a way to use it!

            One thing to consider is that the humidity is heavier than air, so it is most humid at the floor level, which is where your dehumidifier should be. Use an HVAC condensate drain pump as suggested earlier.

            When all else fails, use duct tape!

            "One thing to consider is that the humidity is heavier than air, so it is most humid at the floor level, which is where your dehumidifier should be."

            No, there is not such thing as humidity separate from air. The humidity disperse uniformally in the air.

            And humid air is LESS DENSE then dry air. It does not seem like, but check an chart or calculator for "density altitude".

    Hi,

    I saw a mini pump like that today at HD, but it was $90. It looked like it used small 1/4 inch tube. Here's a link that I found.

    Getting the water into a drain using gravity would be my first choice though!

    They make small "sump pumps" for furnace condensate drains. You could probably rig one of those up somehow............
