Hydro-jetting is not an extremely well-known term (unless you’re in the plumbing industry), so
if you ever do come across it, you may wonder what it is. No, it’s not a carwash. No, it is not a
new watersport. It’s actually a process in which your sewer pipes are scoured by streams of high-
pressure water shooting out of a hose (sounds pleasant, doesn’t it?). Now, why in the world would
you need water shot into your sewer pipes? Aren’t they relatively self-cleaning, you might wonder?
Well, yes and no.
For the most part, your sewer pipes should remain clear and function properly. When there is a
small clog, it can usually be taken care of by pouring something into the pipe or by ‘snaking’ (when a
plumber uses a slender, flexible auger to dislodge clogs in your plumbing). However, there are some
instances when neither of these techniques work (when there are stubborn roots in the sewer line,
for example) and you need something more intense. That’s where hydro jetting comes in.
Although it may seem like a complicated process, hydro-jetting is actually pretty simple. It’s typically
done through an opening called a cleanout, which is present in every plumbing system to allow
plumbers easy access to the pipes. The Hydro-Jetter, which consists of a large tank of water, a high-
pressure hose, a special high-strength nozzle and a machine which pressurizes the water in the hose
so it can spray out at maximum velocity, is then placed ‘downstream’ so it works its way ‘upstream’
against gravity. This allows any debris that is cleaned out by the water to flow downstream where
the drainage path is already clear.
While hydro jetting can easily cut through the most stubborn roots and debris in your sewer
system, keep in mind that it should only be done by a trained professional (don’t go trying to shoot
pressurized water into your own pipes). Also keep in mind that if you continue to have roots
penetrating your sewer line and causing frequent clogs, you probably have a more serious problem
that may require a camera inspection to identify the seriousness of the issue.
