The 550 dual pump combination sewer line jetter and vacuum excavator from Ring-O-Matic fits into spaces too confined for truck-mounted combination rigs, yet can clean sewer lines up to 20 inches in diameter. Powered by an 81 hp Cat turbo-diesel engine, the jet/vac has a 1,000 cfm blower and can deliver 27 gpm at 2,700 psi up to 400 feet with its 3/4-inch hose. The trailer’s axles are rated to 16,000 pounds, enabling the 550-gallon spoils tank and 500-gallon freshwater tank to be pulled behind a 3/4- or 1-ton truck. 800/544-2518;
