Over time, sewer lines can develop leaks, cracks and blockages. A clogged sewer line in fact can become an emergency. Most people put off thinking about sewer line repair because of the work and disruption involved. After all, it means nosy diggers, mud everywhere, the lawn and backyard landscaping ruined, doesn’t it? Not necessarily. With trenchless pipe replacement and repair, all the work can be done with a minimum of fuss and noise.
Trenchless pipe repair has been around for about 15 years, though most people are not aware of it. It makes possible sewer line replacement and repairs with a minimum of digging.
Do your home’s sewer lines need repair?
If your home is 40 years old or more, the sewer lines should be inspected, according to Angie’s List consumer advocate Angie Hicks. Sewer systems can become clogged, or develop cracks and leaks.
Tree roots can do a lot of damage if they grow into a sewer system. They grow downwards only about 1-3 feet into the ground, but can spread outwards around 2 to 3 times the size of the canopy. So even if the tree is not anywhere near the sewer line, its roots may be infiltrating the sewer line and causing breaks, cracks and leaks.
What is trenchless sewer pipe repair?
With trenchless pipe replacement, there is no need to dig up the old sewer line for repairs or to install a new line. Two pits are all that’s needed to install a new pipe and blow up the old one. Most sewer lines are buried at depths of one to two feet, depending on municipal regulations and the type of pipe used. Trenchless sewer repairs eliminate the need to dig messy trenches to remove the old lines.
For clogged sewer lines, a high pressure jet might be used to just blow away roots and other obstructing materials down the line with a pressure of 4,000psi.
How much does it cost?
Trenchless pipe replacement does cost around 30-50% more than conventional digging, but saves money on restoring landscaping and lawns. A survey of homeowners found that 73% would be willing to pay more to avoid digging up their lawns, landscaping, patios, decks, and other outdoor features.
