Problem

A camera inspection revealed that backups at a residence in the Hidden Valley neighborhood of La Jolla, California, were caused by heavy root intrusion in the line. Roots from nearby trees grew into the joints and cracks, blocking the flow of sanitary waste. The pipes ran under hilly terrain from the home’s clean-out in the yard to the city’s main sewer line. Not only were the pipes located 6 to 9 feet below grass and trees in the customer’s yard, but also in the neighbor’s yard.

Solution

Using the Nu Flow Micro-Cutter, Nu Flow America was able to clean more than 200 feet of the 4-inch clay sewer pipe. The system rotates at approximately 2,000 rpm and will negotiate turns of 90 degrees in pipes down to 2 inches in diameter. It runs at 40 cfm and allows for multiple cutting heads to be attached.

Result

Nu Flow America successfully cleaned the root-infested sewer line using existing access points, without the need to dig up the customer’s or the neighbor’s property. Then they installed the Nu Drain Pull-in-Place structural liner to prevent future root intrusion. 905/433-5510; www.nuflowtechnologies.com.
