RootX is packaged as two dry powder components in one container. When these components come in contact with water, they create a sticky foam that fills the entire pipe, coating the roots and pipeline surfaces with the RootX formula. RootX leaves a residue above the water line that continues to kill roots and inhibits new growth for up to 12 months. 3. RootX saves money - RootX can be used with or without mechanical root cutting equipment. Some situations such as heavy root blockage will require mechanical removal of roots. Mechanical removal is an excellent short term solution. However, if the roots are cut and left untreated (just like pruning a tree or bush), they will eventually come back bigger and stronger. This process will eventually destroy a sewer line and require it to be excavated and replaced. The replacement of a sewer line would cost much more than an annual treatment with RootX.
