The Original JetSnake® professional grade sewer jetter helps you thoroughly clean more sizes of drains, from 1-1/2" ID to 4" ID. Helps remove stubborn clogs from main sewer drains, indoor lateral lines, landscaping drains, outdoor drain tiles and septic field lines. Flexible, higher-strength sewer jetter hose has a steel braided center jacket that retains an ultra-compact nozzle end – with unbeatable cleaning force, yet up to 70% more compact than generic poly hose jetters. IMPORTANT INFORMATION:For your cold-water, GAS PRESSURE WASHER (sold separately) rated up to 4.2 GPM and up to 4,200 PSI. DO NOT attempt to connect to an electric pressure washer or directly to a garden hose. COMPARE and MATCH the TWIST FITTING on your TRIGGER GUN with the trigger gun image at the top of this page before ordering.To avoid clogging the sewer jetter nozzle with debris from open hoses, always FLUSH ALL SUPPLY HOSES and YOUR TRIGGER GUN with CLEAN WATER for 30 SECONDS before attaching the sewer jetter.Before ordering, confirm that a low-cost drum auger (Cobra 86250 or similar) can pass its FULL LENGTH into the drain opening; if your drum auger can't pass through the drain, the sewer jetter also WON'T PASS THROUGH.Sewer jetters usually can't pass directly through toilets, bathtub drains, sink traps or laundry drain traps so you may need to REMOVE THE FIXTURE OR TRAP, or use an ALTERNATE DRAIN OPENING to reach the clog.DO NOT USE in clay (ceramic) pipes, Orangeburg (tar composite) pipes, drains that could have tree roots, rocks, or pipes with preexisting structural damage.If you remove the nozzle to clean it, use a soft cloth to clean the exposed male hose fitting threads, sparingly apply removable THREAD SEALANT (sold separately) to the 2nd-4th rows of male threads, re-install the nozzle, and allow to set overnight before pressurizing.
