Abstract
An automated system for a jetter system, a method for automatically filling a sewer access system with antifreeze liquid, and a method for automatically recapturing antifreeze within a sewer access system are provided. The automated system may include: a control system configured to provide a normal operational mode, an auto antifreeze mode, and an auto recapture mode; a pump; first and second tanks, and conduits that connect these components. The system automatically fills the conduits with antifreeze liquid from the second tank and then can automatically purge the conduits of antifreeze liquid and return the antifreeze liquid to the second tank for later use in again filing the conduits with antifreeze liquid.
