It all starts with a call
Hydro-jetting has the power to burst open the toughest blockages and at the same time scours the full diameter of the pipe, flushing debris and leaving lines clear. Short of replacing or relining your pipes, hydro-jetting is the most efficient way to clear pipes of blockages without damage to the surrounding area and infrastructure.
Hydro-jetters use heavy-duty power nozzles attached to powerful hoses and high-pressure water, much like, but more powerful than, a fire hose. The high pressure water in a hydro-jetter literally pushes debris out of the pipes, either breaking it into small pieces or by moving it toward a larger area of the pipe where it can be broken up. Grease and root intrusion are usually the reasons for such blockages.
Here is a video that shows the inside of a side sewer pipe before hydro jetting and inside the pipe after hydro jetting.
