Trenchless technology is a relatively option for pipe repair and replacement, allowing your plumber to replace main water lines or sewer lines under your Rohrersville property without digging a massive trench in the ground. Cost effective and environmentally friendly, this process is designed to minimize the impact on homeowners who are worried about losing their favorite trees or disrupting their neighbors.
But, what exactly is involved in trenchless water line replacement? Here is a quick look at the process and the components involved in each step of it:
- Puller Unit – The puller unit is responsible for pulling the new pipe through the space between the two access points. A cable is attached to the new pipe to pull it through. The size and type of puller unit used will depend on the type of pipe being replaced.
- Bursting Cone- A bursting cone is often attached to the head of the new pipe to break apart the old pipe as the new one is fed into the hole. This makes it possible to feed new pipe without having to remove the old pipe.
- New Pipe – There are a couple of options here including a brand new line of pipe replacing the old one or a liner being fed into the old one to patch cracks and leaks. The repair method used will depend on the severity of the problem, length of the affected pipe and recommendations from your plumber.
- Access Points – Two access points will be dug on either side of the affected pipe line. One pit houses the hydraulic pulling unit, the size of which will vary depending on the equipment used by your plumber and the power needed to pull your new pipe. The second pit is used to feed in new pipe, which means it needs to be slightly larger.
How the trenchless replacement process works depends largely on the pipe being replaced and which repair method you select. If you have a sewer line that has cracked along a five foot length, trenchless pipe replacement may be the best option. However, a smaller problem in your water line like a small crack may be fixed without a full replacement or relining. The best way to know for sure is to call a professional and have them inspect your pipe line. Video technology makes this easier as well.
