ABSTRACT:
An aparatus adapted to be mounted on a sewer vent stack to inhibit frost buildup in cold weather including a supporting frame containing a central rotatable shaft with a wind turbine on the end exposed and four vanes on the end within the vent pipe. The rotation of the shaft will cause frost build up to be scraped off by the vanes. Lack of rotation in a breeze will indicate excessive build up and a possibly dangerous situation.
