Installation Instructions

Kit Description
Retro-DWS is a tubular self-regulating heating system designed for use in 4-inch and 3-inch non-pressurized sewage and waste water drain lines, as well as other large diameter non-pressurized pipes and storm drains. Additional add on kits and fittings may be required for sizes other than 4-inch. Retro-DWS is also suitable for other large diameter non-pressurized pipes and storm drains. The core tube is constructed of HDPE (high density polyethylene) and will push inside most pipes for long distances. They can also be drawn in with a fish tape.
Retro-DWS utilizes a conductive polymer tubular heater technology which provides a barrier from the fluids while providing extremely efficient freeze protection. Retro-DWS can be used as a system to prevent freezing or as a precautionary system. If the drain waste or sewer freezes, the system can be energized to begin the thawing process.
Retro-DWS is supplied with all of the necessary fittings to fit a 4-inch pipe (3-inch kit optional add on) at a clean out or other entry point. The RetroDWS can be easily adapted to fit larger pipe diameters if required by using readily available, industry standard components.
Available with Ground-Fault Protection (GFCI) or Cord-Set (CS) both in 120 volt and 240 volt.
