A cable snake clears a path through a blockage — it opens a channel wide enough for water to flow again. Hydro jetting does something different: it uses a pressurized water stream, delivered through a specialized nozzle, to scour the entire interior wall of the pipe, removing grease buildup, mineral scale, and fine root mass rather than just punching through the obstruction itself.
How the Process Works
A flexible hose feeds a jetting nozzle into the line, usually starting from an existing cleanout or access point. Once positioned past the problem area, the nozzle sprays high-pressure water backward as it's pulled through the pipe, which both propels the hose forward and blasts material off the pipe walls on the way. The result gets flushed out through the same access point, and a camera inspection often follows to confirm the line is fully clear rather than just passable.
When Jetting Is the Right Call
A line has been snaked more than once for the same symptom
If snaking keeps opening a path but the clog returns within weeks, that usually means buildup along the pipe wall rather than a single obstruction — exactly what jetting is built to remove.
Camera inspection shows buildup, not an object
When a video inspection reveals grease coating or scale narrowing the pipe rather than a discrete blockage, jetting addresses the actual cause instead of temporarily restoring flow.
Maintenance for older cast-iron lines
Cast-iron stacks common in Brockton's pre-1950s housing accumulate grease and scale over years of use even without an active clog. Periodic jetting as maintenance can keep that buildup from becoming a full blockage.
Is It Safe for Older Pipe?
This is the most common question we get about jetting, and it's a fair one — a century-old cast-iron stack and a newer PVC line don't respond the same way to high pressure. We use professional-grade jetting equipment sized to the pipe diameter and condition, and we adjust pressure based on what a camera inspection shows about the pipe's actual state. Jetting isn't the answer to every clog, and we'll tell you directly if a cable snake is the more appropriate — and less invasive — choice for your specific line.
