Retro-Line is an in-pipe heating cable system used to keep pipes from freezing. It is easily installed inside existing water pipes without the need to excavate and is one of the few water line freeze protection systems certified Drinking Water Safe as per NSF/ ANSI 61 regulations. Retro-Line systems are supplied complete with the necessary plumbing components, self-regulating heating cable and job-ready plug end.

The Retro-Line system can be installed in many different types of water pipes. In this video we look at how to install the system in copper pipes as opposed to the more common polyethylene pipes.

Retro-Line is a solution to internally freeze protect many different fluid pipe applications. This includes but is not limited to: residential water supply from wells, lakes, rivers, building to building and sump pump discharge lines and pressurized or high-volume water drain pipes which may consist of either metal and non-metal piping material. Retro-Line can be ordered with a threaded male adapter to allow easy interfacing with pipe types and sizes such as ABS, PVC, PEX, copper, galvanized and steel. For polyethylene pipe applications Retro-Line is supplied with a compression style fitting for easy connection to the pipe.

Retro-Line can be used as a system for water line freeze protection or as a precautionary system to use only if pipe frost protection is needed for a freeze-up. Even in applications where the pipes are intended to be dry for short or extended periods of time such as sump pump lines, the Retro-Line presents no danger of overheating or melting the pipe. This makes the Retro-Line suitable for all pipes, even plastic which does not always contain liquids.
