Abstract
Abstract A device for allowing the escape of water from residential or commercial wall constructions. The device is particularly suitable in brick veneer walls to permit the escape of water which would otherwise penetrate the brick, window, or other wall areas, and collect between an inner structural wall and the brick veneer. The device includes a tube having a water outlet and inlet with an elongated durable porous wick material which extends outwardly from the water inlet to absorb moisture whereby the water seeps from the wick end to the outlet end. The outlet end may also have a screen cap to prevent pests from entering. The extending member prevents debris from clogging the inlet and collects water by sorption for feeding to the entry port whereby the water is channeled through the wall to the exterior of the building. The device prevents severe damage to buildings which might otherwise occur because of water, weather, pests and the like.
