Photo Album: Drainage Matting/Smart Sump in Casscoe, AR
Since you don't go into your crawl space a lot, you need to know if there is a plumbing leak. The SmartSump has a unique lid design so water from a plumbing leak fills an alarm pocket on the lid first, sounding a WaterWatch alarm. From there, the water flows down a special airtight floor drain that lets water down, but damp air cannot come up into your crawl space. The alarm also alerts you to pump or power failures.
Moisture
Dirt crawl spaces have the high humidity levels necessary for mold growth. Humidity levels from 50-90% are easily found in dirt crawl spaces that have never flooded.
Outside Air
Outside air can add moisture to the crawl space, and makes the house harder to air condition as all this moisture needs to be wrung out of the air.
Smart Sump
Part of keeping your crawl space dry involves a sump pump.
