Hello; I would like to make my basement a little more usable and therefore will need to improve the high humidity and ventilation issues. The basement does not have any leaks but does have a sump pump that might run a couple of days in the spring time. I am trying to find an economical system that will work to increase the air flow. I saw a system called "The Wave" ventilation system but it must be installed by their contractors. Does anyone know of a similar system that can be installed by the homeowner or have any suggestions other then running an expensive dehumidifier all the time. Thanks

OK...let me start off with this is not my house yet....but I am considering buying it from the bank. The last two times I visited the basement, there were no leaks around the sewage pipe that goes in the wall in the basement. Today I went to take some pictures and take another look ah the house and my real estate agent noticed water dripping off of the 4" septic pipe that goes out to the yard. I verified that the pipe was not leaking above where it was dripping by running my hand around the pipe...it was dry. It appears that the water is coming through the outside of the wall through the seal. We went outside to notice a downspout that empties about 4 feet away from the leak. So...my question is....is it possible for the water to find it's way 4 feet across and about 4 to 5 feet deep and going through the outside of the pipe and coming inside? That is my best guess. Recommendations? I know that the gutter downspout is an issue...it would need be fixed so the water goes away from the foundation. Do you think I would have to dig this thing up and reseal this from the outside? I would have to imagine this could be costly? Thanks...
