How do you cut out roots from corrugated drain pipe?

To cut out tree roots from a corrugated drain pipe, follow these steps:

1. Locate the roots: Use a drain snake or camera to inspect the interior of the pipe and identify the location of the roots.

2. Excavate the pipe: Dig up the section of the pipe that contains the roots, using a shovel or backhoe. Be sure to dig a wide enough trench to expose all the roots.

3. Remove the roots: Once the pipe is exposed, use a hacksaw or root saw to cut the roots. Be careful not to damage the pipe while cutting the roots.

4. Replace the pipe: Once the roots have been removed, replace the section of pipe that was removed, and secure it in place.

5. Backfill the trench: Backfill the trench with dirt, and compact it to prevent settling.

6. Prevent future root growth: To prevent future root growth, apply a root-killing chemical to the area around the pipe. You can also install a root barrier to physically prevent roots from growing into the pipe.
