Primary Municipal Nozzles:

Primary Municipal Nozzles are the first nozzles used to clean stoppages and blockages within large lines. They are for unclean, unchecked, undone pipe and are run quickly through pipes to break blockages and level out piles of debris.

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.

STEP 1: Primary Municipal Nozzles:
