The Warthog WGP-1 nozzle by StoneAge is designed to produce up to 40% more pulling power than the WG-1 nozzle. The rear facing jets are angled more sharply and the centralizer fins have also been streamlined. The result is more pulling power to navigate longer lines and moderate inclines, plus makes retrieval of the nozzle easier. Descaler models combine the benefit of the WGP-1 design along with having a Descaler head. This allows a higher level of cleaning when scale, tuberculation, corrosive products, soaps and minerals build up on the sewer walls, especially in lines with numerous bends and transitions. This nozzle is rated for 50 to 80 GPM and up to 5000 PSI. The working sewer line size for this WGP-1 nozzle is 8" to 36" diameters.
