HOUSTON – Some plumbing problems can be easy to miss — especially when the trouble is happening underground.
Tree roots can make their way into sewer lines through cracks or breaks in older pipes. Once they get inside, they continue to grow, potentially causing recurring clogs, leaks and other costly problems.
Master plumber Robert Koster of Mission AC & Plumbing has seen it firsthand. In one River Oaks home, he says a root grew about 12 feet long inside a sewer line. Plumbers jokingly called it a “poop root” because of where it was growing.
You can hear the story and see a photo of the unusual root in the full interview above. Robert also brought a section of an older cast-iron pipe to the Houston Life studio to explain how pipes can deteriorate over time.
Signs of a plumbing problem
Koster says homeowners should pay attention to changes around the house and in the yard. Some potential warning signs include:
Older cast-iron pipes can also be a concern. Koster says they generally have a lifespan of about 45 to 60 years, although factors such as what goes down the drain can affect their condition.
He also recommends being careful about what you flush. Toilet paper is designed to dissolve, but Koster advises against flushing wipes, paper towels and other products that may not break down the same way.
