Product Review
The SewerFlexâ„¢ sewer jetter for gas-powered pressure washers is designed to thoroughly clean main drains, landscaping drains and septic field lines from 3" ID to 4" ID. Helps you thoroughly scrub and flush larger drains that have long-sweep sewer elbows.
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.
- This poly hose sewer jetter is designed for 3" to 4" ID drains that have long sweep sewer elbows; NOT recommended for use in drains less than 3" ID.
- 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.
- DO NOT USE in clay (ceramic) pipes, Orangeburg (tar composite) pipes, drains that could have tree roots, rocks, or pipes with preexisting structural damage. CANNOT pass through shower floor drains, sink traps, laundry drain traps, toilets, short radius elbows and fittings, and most indoor lateral lines.
- If you disassemble the nozzle to clean it, use a soft cloth to clean the exposed male hose fitting threads, sparingly apply removable Loctite 545 or equivalent THREAD SEALANT (sold separately) to the 2nd-4th rows of male threads, re-install the nozzle, and allow to set overnight before pressurizing.
Note: also cleans up to 6" ID drains if your pressure washer is rated 3.0 to 4.2 GPM.
