Sewer Pro Shop’s Blue Star sewer cleaning nozzles are manufactured with optimized 3-D hydromechanics by Intersewer, located in Germany. Water coming from the pressurized sewer hose is first divided by a conically-shaped piece and turned around in the nozzle chamber, then guided directly to the stainless steel nozzle inserts via 5-axis CNC precision. The nozzles are made in one piece, reducing the chance of failure under pressure for greater safety and performance. Utilizing case-hardened steel, stainless steel and ceramic inserts, the nozzles can also be used with recycled water. 877/864-9394; www.sewerproshop.com.
