Using J-1730D as the source example, assess pipe dimensions/material, bends, blockage and water. Pressure/flow alone do not establish fixed working limits.
Identify the pipe and blockage first
The J-1730D is specified at 170 bar (17 MPa) and 30 L/min. Pressure loosens deposits and soft obstructions, while flow transports grit and grease. Check pipe diameter, material, length, bends, access and blockage severity.
Match nozzles and water supply to the plan
Match the nozzle, working hose and continuous supply to the pipe. Inspect roots, solid obstructions and suspected collapse separately. Verify allowable bore and useful reach from site evidence.
Checks after reading
- Site area, routes and narrowest access
- Floor, dust, oil, debris or pipe-blockage type
- Daily frequency and continuous working time
- Power, water, wastewater, consumables and service conditions

What does this article address?
Using J-1730D as the source example, assess pipe dimensions/material, bends, blockage and water. Pressure/flow alone do not establish fixed working limits.
What site information is needed before equipment selection?
Provide area, aisle width, floor/pipe conditions, contamination, frequency, power/water, city and budget range.
Do pipe diameter and blockage still need a site trial at 170 bar (17 MPa) and 30 L/min?
This article offers selection guidance. For complex sites, heavy contamination or continuous work, verify models and configurations through equipment information, video or a trial.
