Sewer Jetting Pressure and Flows

Water is a powerful cleaning tool. You use high pressure water to clean debris off the sides of pipes, and you use the volume of water or “flow” to flush what was clinging to the side of the pipe downstream. The high pressure water is introduced to the sides of the pipe with a jetting hose capped on the business end with some sort of nozzle, which restricts the flow of the water coming down the hose and allows it to escape the hose via small orifices drilled into the front, sides or rear of the nozzle. These jetting hoses can be as small as ¼” diameter, or as large as an inch or more.
