Hydro Jetting & Root Intrusion: SAC Reader Response #2

Roots can get into a sewer line, causing leaks, clogs and damage to the pipe, causing a great deal of inconvenience for a family. Traditional methods of getting rid of the roots were quite expensive. A newer method, using hydro jetting, is helping homeowners save money.

What Is Root Intrusion?

Root intrusion means that tree and shrub roots are growing into your sewer line. This is a very common problem because roots naturally seek out moisture. And of course, sewer pipes have moisture in the form of a constant flow of wastewater.

If there is any gap or joint in the sewer pipe, the tree will try to enter at that point. The roots get access to the water and start growing, multiplying and expanding. This is what causes the damage to your sewer pipe. The structure of the spipe deteriorates and the entire thing eventually collapses.

Traditional Repair

The standard way of fixing the sewer line for many decades has involved:
l Removing the tree
l Digging up the yard to locate the area where the roots invaded the line
l Excavating the line
l Replacing the sewer pipe

All of this meant that your landscaping took a hit. Not only did you lose the tree, you ended up with trenches in several locations around your yard.

Modern Methods of Fixing Root Intrusion

Newer methods have been developed that involve less mess and destruction, including video camera inspection, NDE And NDT Inspection, hydro jetting and trenchless pipe lining.

A video inspection is done of your sewer line. During the operation, a video camera with a radio transmitter is sent through your line. It pinpoints the cause of the problem and its location. The plumbing contractor can see what the camera sees in real time on a monitor above ground.

Hydro Jetting

The next step the contractor uses is professional hydro jetting, which involves shooting a high-pressure stream of water through the pipe system. Using water that races through the pipes at 3000 to 8000 PSI, it gets rid of clogs and roots quickly and thoroughly.

The jetting action is done with scalding water, which makes it more difficult for debris to collect once again. The strength of the water is powerful enough to take out roots with ease.

Pipe Lining

After the root is removed, the sewer pipe needs to be fixed. The most effective ways are pipe lining, also called trenchless technology, methods. There are two main ways that a contractor can repair sewer pipes without digging up your yard.

Pipe lining. This is commonly called CIPP, cured-in-place pipes. The method involves sending a flexible tube through the damaged pipe and then inflating it. This tube has been coated with resin, which hardens and creates a new pipe-within-a-pipe.

Pipe bursting. With this technique, the contractor pulls a new tube through the old pipe. At the same time, the old pipe is fractured in an outward direction, leaving just the new pipe.

In both cases, just one or two access holes need to be dug. This saves on restoration costs, is much less messy and takes less time to accomplish.

Hydro jetting is part of a comprehensive approach to root intrusion into your sewer pipe. It can speed up the repair work and restore sewer usability quickly.
