The Warthog WH nozzle by Stoneage are best suited for larger lines and higher GPM flows. StoneAge utilizes a slow, controlled rotation to maximize dwell time of the water to get a better clean of sewer lines. The nozzle is best suited for sewer lines from 6" to 12" in diameter and up to 500' in length. The WH models with a descaler head allows a higher level of cleaning when scale, tuberculation, corrosive products, soaps and minerals build up on the sewer walls. It does this with two additional 105 degree jets combined with a plug on the front insert for maximum sewer wall cleaning. This StoneAge nozzle comes with its own centralizer skid. The WH nozzle comes in 1/2" and 3/4" sizes. Be sure to select the correct configuration for your jetting application.
