Great for a wide range of heavy-duty plumbing, drain cleaning, maintenance and rental applications, the Typhoon trailer jet from General Pipe Cleaners blows away blockages in big lines and long runs, the manufacturer explains. The Typhoon delivers 12 gpm at 2,500 psi to blast grease, sediment and debris from 4" to 12" drain lines up to 400' long. A 200-gal. holding tank carries enough water to handle remote locations where access to water is limited.
