Advanced Nozzle ExtensionsSkids from Sewer Shark make it quick and easy for operators to identify the right-sized skids, which helps to prevent repeat cleanings. The nozzle skid is an important, often overlooked part of jet cleaning. It’s important that a proper-sized nozzle extension be used to maximize the cleaning power of advanced nozzles. In smaller pipelines, a proper-sized skid will roughly center the nozzle in the line while allowing room for minor offsets and obstructions. This will evenly distribute cleaning force to the top and bottom of the pipe. When a 6-inch skid is used in a 12-inch pipe, the bottom half of the pipe receives 75 percent of the cleaning force. 888-907-4275; www.sewersharkmfg.com.
