Earlier this winter I installed two types of drain line heating cables. One fastens to the outside of a fully exposed insulated pipe underneath a building on raised piers, and the other sits inside a buried drain pipe.

Their Retro-DWS system I installed includes a self-regulating heating cable that’s sealed inside a 1/2” diameter HDPE pipe. Technically speaking the cable is not inside a drain line, it’s inside a pipe that’s inside a drain line. This makes it okay for cCSAus certifications.
