Humidity Venting

[CalG]

My "semi finished"walk out basement runs around 62%RH on days like today.

Dehumidifier running pretty steady and a wall unit A/C to boot. ' 65% and above, and the machine tools start to rust. ;-)
We use more electricity in summer keeping things dry than for any other use year round.

Get a dehumidifier with the option of a hose drain. Since you don't have a basement drain, run the hose drain from the dehumidifier to a Little Giant condensate pump sitting on the floor next to the dehumidifier. Then run the output hose of the Little Giant through a hole in the sill plate outside to a point downhill from the house. You can get a condensate pump like this for under $30.

I like the humidor idea! Maybe store some nice wine too! Otherwise it does sound like you are in the market for a dehumidifier with ideally with a way to drain to make it low maintenance. Good luck.

Good idea.

Set up some kind of resevior with float. Maybe a timer to turn it on. Make sure can handle amperage. I could probably turn mine on daily in summer.

Could also put a croc in floor with a float, pumps to sewer. I have one that goes to a slop sink, and a drain, which my AC runs into. May not be code, but could run it outside.

'They' make small condensation pumps. I have one on my high efficient natural gas furnance. Has internal float switch to pump stuff 'overboard'. Capacity is quite small (maybe a quart or so) but works great. Located on my garage floor and pumps 8ft up and 20ft over and outside. Only thing I needed to do is make sure the outside exit point of the tube doesn't freeze. Learned the hard way when I flooded the garage floor during a cold snap the first winter.

That Little Giant has its own reservoir and float switch. Its the same kind of pump used on many air conditioner units to pump AC condensate water up to the ceiling in a basement, through a check vavle, and into a drain line.

Is the floor concrete or earthen? Any leakage at walls or wall/floor with rainstorms? How much of the foundation is exposed above grade on the exterior? Is this a frame house with wood siding or brick veneer? Need more info to see how to fix your problem...Thanks

Concrete floor; no leakage at any time; 30 ish inch crawlspace; brick/mortar foundation; frame house with aluminum siding

We just dump our basement humidifier water into the clothes washer before starting a laundry load. Obviously that only makes sense if your clothes washer is also in the basement.

Best solution I've seen yet.

I had humidity problems in an old house with a stone foundation. Hung an old box fan next to a basement window and left it on 24/7. A little foam insulation on the pipes that were sweating and the problem went away. You need to vent and circulate the air.
