I finally dropped $300 on a real dehumidifier, my basement is still growing mold
Last spring I got sick of wiping black spots off my storage boxes so I bought a big 50-pint unit from Home Depot in Tulsa. Thought it would fix everything since the air felt drier, but the mold came back within a month. The guy at the store said the unit was fine, turns out my sump pump pit was the real problem leaking moisture up through the floor. Before you drop serious cash on any appliance, check where the water is actually coming from, has anyone else been burned by a fix that only treated half the issue?
Did the Home Depot guy actually test the unit or just tell you it was fine? Because if your sump pit was pushing water vapor up, that dehumidifier was basically trying to dry out a room with the tap running. Have you checked if the pit has a cover or if the pump is cycling way more than it should?
