Removing heavy root blockages in limited access environments

Problem / A two-story building in Southern California was experiencing a backed-up line despite the efforts of a previous plumbing company to snake the line. Nicholas Krewson of San Diego Drain Krew found that the line was blocked by heavy root intrusions. To be positioned effectively, the hose would need to be run into the building from its roof. Adding further complexity to the situation, the roof could not be easily accessed by ladder, and the building was designed with back-to-back toilets. In order to prevent an emergency dig-up, the property needed a solution to resolve the blockage and restore flow without damaging the pipe walls.

Solution / A 1/2-inch Warthog Flexible SuperSpin nozzle (WS-1/2) from StoneAge was used in conjunction with a water jetter to effectively clear the roots. Equipped with the nozzle and jetter hose, Krewson climbed to the roof of the two-story building to gain the access needed. First, the line was scoped with a camera to identify the extent of the root intrusions. As the hose was lowered 120 feet through the building via a roof vent, the side-to-side flexibility of the unit’s inlet hose shortened its rigid length to more effectively navigate the limited access environment and remove the roots.

Result / The nozzle cut through the roots blocking the line to restore flow without causing damage to the pipe walls. Resolving the root blockages enabled the property to complete installation of a set of two-way clean-outs for easy future maintenance. 866-795-1586;
