Secondary Municipal Nozzles:

Secondary Municipal Nozzles are used to get up lines quickly. These nozzles have a wider angle than Primary Municipal Nozzles and are designed to flush out the debris from the pipe bottom. They are not designed to clean the entire circumference of the pipe. Secondary Municipal Nozzles are used after Primary Municipal Nozzles and before Tertiary Municipal Nozzles.

Municipal Nozzles include 3/4", 1", 1-1/4" and 1-1/2" nozzles. These nozzles are used to clear blockages and flush municipal lines. Typically these nozzles are used to clean pipe diameters from 6 inches and above. They are categorized into three steps and clean most effectively when used in our recommended series.
