Plumber employs multiple rehab methods on challenging job

Problem: Steve Allen from Allens Plumbing in Maui, Hawaii, had a pipe rehabilitation job that could not be fixed with a single pipe rehabilitation method. The project at a condominium included a leaking plumbing stack, a root-infested sewer from the building to the street with part of the line collapsed, and another section of drain-waste-vent piping that had a hole in it with the rest of the pipe in need of corrosion protection.

Solution: Allen fixed the collapsed section of the lateral out to the main with his pipe bursting technology. Stringing a cable through the collapsed line allowed him to pull in an HDPE pipe from the building to the right-of-way. He then used Pipe Lining Supply’s Quik-Shot CIPP lining equipment to line the pipe from the right-of-way to the main at the clean-out he installed. Inside the building, he applied a pipe patch to cover the hole in the missing section of cast-iron drain-waste-vent and then used the Quik-Coating polyurea coating system to provide corrosion prevention, providing a 50-year life expectancy. The key to the job was cleaning the pipe, which Allen’s crew performed with a high-speed cable machine equipped with chain knockers.

Result: The multiple rehabilitation methods employed by Allen have proven successful, and the condominium owner was pleased with the result. 888-354-6464; www.pipeliningsupply.com.
