1/2" WH Warthog Classic Rotary Nozzle

CLICK HERE FOR 3/4" WH VERSION

When the job calls for serious cleaning power, the Warthog® WH Classic 1/2" is ready to go to work. Trusted by plumbing contractors, drain cleaning professionals, municipalities, and trenchless operators for more than 30 years, this proven nozzle delivers the consistent performance you need to clear tough blockages and keep sewer systems flowing.

Engineered for cleaning 6"–24" sewer lines, the WH Classic uses Warthog's proven Controlled Rotation Technology to cut through tree roots, grease, sludge, scale, and stubborn debris while providing thorough wall-to-wall cleaning on every pass.

Designed for trailer jetters, van-pack systems, truck jetters, and smaller combination jet-vacs, the 1/2" WH Classic offers the same dependable performance as the larger 3/4" model while pairing perfectly with jetters producing 14–30 GPM (18–25 GPM recommended). Its repairable, rebuildable design and rugged centralizer make it a smart investment for professionals who depend on reliable equipment day after day.

Available Configurations

Standard Configuration

The Standard configuration features two rear jets and one front coring jet, making it an excellent choice for everyday sewer cleaning and preventative maintenance. It provides a balanced combination of cutting, pulling, flushing, and full-pipe cleaning performance, helping remove grease, sludge, roots, and general buildup with confidence.

Descaler Configuration

When heavy scale and mineral deposits are the challenge, the Descaler configuration is built to handle it. Featuring four rear jets with two wide-angle side jets and an optional front coring jet, this setup delivers increased impact against the pipe wall for faster, more aggressive cleaning.

The side jets are designed to reduce the distance between the water stream and the pipe wall, increasing cleaning efficiency while improving polishing and descaling performance. Choose the front jet for penetrating blockages or plug the front port to maximize pulling power and wall-cleaning action.
