Ring-O-Matic’s 550 Dual Pump Combination Sewer Line Jetter and Vacuum Excavator fits into spaces too confined for truck-mounted combo rigs, and can clean sewer lines up to 20” in diameter. Powered by an 81 hp CAT turbo diesel, it features a 1,000 cfm blower and can deliver 27 gal. per min. at 2,700 psi up to 400’ with its 3/4” jetter hose. The trailer’s axles are rated to 16,000 lb., allowing the 550-gal. spoils tank and 500-gal. freshwater tank to be pulled behind a suitably equipped 3/4- or 1-ton truck.
