I get a medium amount of seasonal musty smell in the basement (finished) in our rowhouse. We usually run a room dehumidifier in the spring and summer, and occasionally during very rainy periods, and that takes care of things. However, it is a dehumidifier with a bucket that has to be manually emptied. We don't have a floor drain or sink anywhere in the basement. I have done a bit of research and am considering connecting the dehumidifier to a condenser pump, and running the tubing up to a pipe that would lead to the outside. Before I have the plumber come, would like some input on this plan. I think I can set everything up, but need a pro to drill the hole and probably to run the pvc and seal off the hole. We do not have central air, btw so there is no existing condenser drain or output. Questions: 1) will a condenser pump have enough power to push the (at most) 5 gallons of water per day (in the height of the muggy summer) up to above ground level (around 4-5 feet)? We would likely install right by the wall it would go out through, so it wouldn't have far to go other than up and maybe 3-4 feet out. 2) Is it okay to have a drain come out the front of the house? I'm thinking of having it come out next to the concrete steps, which slope toward the sidewalk. It would generally be a trickle when it was running. 3) Am I better off getting a new dehumidifier with a built in pump or keep them separate? My instinct was that having the two separate would mean it's easier to replace a single item as needed without having to replace or repair the whole thing. But there may be good reasons for having a built in pump in the dehumidifier. 4) Is a plumber the one to do this? I assume they would have the right kinds of bits to drill through a stone/concrete foundation wall, and to seal up the seam around the pvc correctly. Thanks for any input, including if there are better options. Hoping to get this done by mid-December.
