At 2 3/4 inches long, the Rotodrill Bend nozzle from Enz USA easily negotiates traps and bends. The high-powered rotating jet provides thrust power and is effective for moving debris and tree roots and clearing blocked pipes. It pushes itself through pipes via a tapered front. The efficiency of this nozzle is generated upon retrieving it from the pipe, as it cleans and cuts out roots and deposits upon return. It can operate on flow as low as 4 gpm, while cleaning pipe ranges from 3 to 6 inches in diameter. It is available in 1/4- and 3/8-inch connections. 877/369-8721; www.enzusainc.com.
