How Does Trenchless Sewer Replacement Work?

Trenchless No Dig Sewer Installation
Magic Plumbing uses the Tric Trenchless Plumbing -No Dig system, which works by digging two holes, one where the sewer exits the building and the other at either the property line or in the street where it connects to the mainline. A steel cable is then threaded through the old sewer pipe and a hardened steel bursting head is attached to one end of the cable. The new polyethylene pipe is then attached to the back of the bursting head. At the other end the TRIC hydraulic system is set up which pulls the cable. Once the system has been set up and turned on the operator uses a remote control to "pull" the cable with the head and pipe attached down into the hole at the side of the house. It then pulls the new HDPE pipe through the old pipe breaking it and pushing the pieces out into the surrounding soil. The new pipe gets pulled all the way to the exit hole where the connections are made, it is inspected and then the holes filled in.

Trenchless Sewer Line No Dig Replacement How much does it cost?
It all depends on the location. Depending on the hardscape (What's above the pipe being replaced), the price might range between $100 and $200 per foot.

Is it cheaper than just having my sewer line dug up and replaced? Usually. Much of the cost of a sewer replacement job is in the restoration of the property that had been dug up. The TRIC trenchless system helps greatly in minimizing restoration costs and the savings can be passed down to you.

How long does it take?
The actual "pulling" or bursting of the old pipe usually takes less than one hour but sometimes a little longer. The entire job from preparation of the holes to making the final connections is often done in a few days.

Trenchless Sewer Line Replacement

What type of pipe do you use?
Our trenchless system primarily uses HDPE or High Density Polyethylene Pipe as the replacement pipe. This pipe is superior to other traditional pipe such as clay, cast iron or pvc plastic piping. HDPE pipe is inherently corrosion resistant, leak tight because the pipe is fused or melted together where the joint is stronger than any other part of the pipe, and highly flexible. For trenchless installation it is the pipe of choice.

What is the difference between this process and just having my sewer replaced with traditional methods?
The biggest difference is that the trenchless sewer installation system minimizes destruction to your landscaping and hard surface areas such as driveways and concrete. By only digging two small access holes the process preserves what otherwise would have to be dug up and replaced by traditional methods of pipe replacement.

How long does the new HDPE pipe last?
HDPE pipe has an estimated life of well over two hundred years.

What is the warranty on a trenchless sewer replacement done this way with HDPE pipe?
We guarantee the pipe will not fail in your life time.

Your sewer can be replaced without digging up your stairway, driveway or garden -- saving thousands of dollars in additional costs.
