The MaxLiner System, a preferred solution for relining laterals, roof drainsand interior pipelines, was chosen by the Emmy Award-winning home improvementseries “This Old House” to help fix a root-infested sewer pipe as part of an18-episode renovation on a nearly 100-year old, two-family home in East Boston,Mass.

The show, which aired in early November, walked viewers through thestep-by-step cured-in-place pipe (CIPP) process, which effectively relines theoriginal pipe to create a new pipe within the existing pipe without any digging.

The root infestation caused breaks in the lateral pipe and sewer backups inthe basement. The multi-diameter lateral, consisting of 4-in. cast iron for thefirst third of the pipe and 6-in. clay for the remainder, was approximately 35ft from the basement cleanout to the city sewer main. A 5-in. woven polyesterliner called MaxWovoLiner was used because it creates a smooth, seamlesstransition in pipes with multiple diameters.

The five-step process involved: removing roots from the pipe; mixing theepoxy; wetting out the liner; using air pressure to insert the liner into thepipe; and using a hot water curing process. The liner was cured in less than twohours using the HotKick hot water curing system.

Using the MaxLiner System, the entire sewer line from the basement out to thecity sewer was effectively relined, forming a watertight barrier impenetrable byroot intrusions. In less than one day, the cracked and defective pipes were likenew and 100 percent flow capacity was restored.

“It’s important for homeowners to understand they have options to tearing uptheir lawns when it comes to fixing their deteriorated pipes,” says Tim Moody,MaxLiner northeast sales representative. “Most often, relining pipes is theright method because it only takes a few hours and prevents damage to thelandscape above the ground or the many gas, electric, cable and water lines thatare below every street.”
