AUTOMATIC SEWER CLEANING SYSTEM

摘要

The sewer system is designed for a building comprising a sewer line and a plurality of plumbing fixtures connected to the sewer line for carrying the discharge sewage from the fixtures into the line. A flexible sewer cleaning cable is permanently installed inside the sewer line. A motor is permanently coupled to the cable and is adapted to selectively rotate the cable inside the sewer line, thereby to prevent material from collecting inside the sewer line. The motor will rotate the cable for time intervals determined by the sewer line characteristics in accordance with a prescribed preventive maintenance program.
