Sewer Jetting

What is a sewer jetter used for?

Cities and city contractors use jetters and vacuum excavators to clean catch basins, storm drains, laterals, and sewer lines. No manager wants the call that sewer lines are backed up, but a well prepared team will have a sewer jetter on hand and ready for a quick deployment. A sewer cleaning project can be done in multiple ways, however sewer jetting is proven to be one of the fastest and most efficient methods.

Sewer Line Cabling vs. Drain Hydro Jetting

The cabling option can usually break up a clog but will leave behind a lot of build-up on the pipe walls. The hydro jetting system is able to break through clogs safely in your pipes, and completely clean the pipe walls. It’s high-pressure jetting action of the water makes it harder for debris to begin accumulating again.

The Power of the Nozzle

When comparing to a traditional power washer, the sewer jetter nozzle has multiple differences making it optimal for pipe cleaning. The pulsating action from the front helps break down materials much quicker. This helps clear the way for the jets that are coming from the rear of the nozzle that are creating a circular motion to further clean within the pipe. While the rear jets clean, they’re high pressure also helps move the hose further down with ease.

The nozzle is attached to a flexible hose that snakes down back and forth without much effort from the operator due to the power of the jet nozzle. This process removes roots, grease, and any buildup along the way.

The range of psi is usually between 1,500 – 4,000, and the gallons per minute are from 2 – 35 GPM. What you’ll need for your project depends on the type of pipe that you’ll be working in most often. For a 3” to 12” pipe your jetter pump should be around 12 GPM and between 2,000 to 4,000 psi.

Combining vacuum excavation

Having a vacuum excavator on site while sewer jetting makes a project’s cleanup more systematic. It ensures that the job is completed timely, safely, and cost effectively. The large storage tank connected to the vacuum allows you to safely remove debris from the site and keep surrounding areas clean. There are units available with both the jetter pump and the vacuum excavator on the same trailer.

As an example, The Vac-Tron MC 573 or 873 SDT has a water flow of 15 gallons a minute, 3000 PSI, and a hose length of 500’ with a ½ diameter line. This unit also comes with a 1000 cfm vacuum and 500 or 800 gallon storage tanks.

Vacuum excavation and hydro-jetting almost go hand in hand. Once the debris is broken up at a project site, you’re going to want to remove that debris in the safest way possible; it’s important to consider your surroundings and make sure that unnecessary damage doesn’t occur in order to keep costs low and employees safe.
