MaxLiner Featured On Ask This Old House

MaxLiner, a manufacturer of a turnkey set of cured-in-place pipe (CIPP) equipment, accessories and materials, has been featured in another episode of the Emmy Award-winning Ask This Old House television series. The MaxLiner system was also highlighted in a 2006 episode of This Old House, which featured the complete renovation of a 1916 East Boston home.

The newest episode of Ask This Old House to feature the MaxLiner System – Season 10, episode 25, Scene Selection 4 – first aired in March of this year. Showcasing a residence in Dallas, the dry Texas climate presents special problems where tree roots are constantly seeking any source of water – in this case, the lateral lines under the foundation of a single family home.

Roots were a chronic problem for this property, and the homeowner called on a drain cleaning company approximately every six months to clean out the roots. The problem recurred, however, because the roots were not removed; they were simply cut. As a result, they always grew back and continued to present an ongoing, costly problem that needed to be corrected, on average, twice a year.

The MaxLiner System put a stop to this cycle, once and for all.

Chuck Berry of Hoffman Southwest was on-site during the filming of Ask This Old House to inspect and repair the laterals. “An initial inspection from the foundation of the home out to the clean-out, approximately 50 feet, revealed no major problems” explained Berry. “We continued the inspection, looking for crushed pipe or roots growing into the joints, but we saw nothing.”

The team reversed the CCTV camera and focused their attention on finding broken pipe or roots beneath the home’s foundation. While the pipe was drained and cleared just a couple of months earlier, the team uncovered the presence of new roots, especially at the joints.

“Our greatest objective is to find solutions for our customers that will give them peace of mind,” continued Berry. “This homeowner was spending time and money every six months or so to have roots cut, only to see them grow back. We quickly got to work to reline his existing lateral pipes so this problem would be solved, for good, without digging up his foundation or yard. We chose the MaxLiner System for this project because it’s compact and super easy to use and maneuver in virtually any location.”

The team began by cleaning out the damaged lateral sewer pipes, preparing for the rehabilitation. The pliable three-inch Wovoliner tube was then saturated with MaxPox, a styrene-free, non-shrink epoxy resin and hardener. Next, using the MaxLinerGun, the tube was inverted with air pressure into the existing, cleaned-out sewer pipe. Finally, an inflatable bladder was placed inside the liner, filled with cold water and expanded fully until the liner fit tightly against the existing pipe walls.

After two hours of curing with hot water, this new “pipe within a pipe” resulted in a rehabilitated lateral that will resist future root growth and damage with reliable, long-term structural integrity.

As the first CIPP system to receive code-compliancy from the International Code Council (ICC-ES), MaxLiner makes it easier than ever for installers to renew not only laterals, but also the toughest vertical pipes and downspouts.
