How Do Professional Plumbers Repair or Replace Sewer Lines?

Professional plumbers typically use the following steps to repair or replace sewer lines:

Inspection: The first step is to inspect the sewer line to determine the extent of the damage and identify the cause of the problem. This may involve using video cameras to inspect the line and locate the blockage or damage.

• Clearing the line: If the problem is a simple blockage, the plumber will use a sewer snake or hydro jetting to clear the line.

• Repairing the line: If the damage is minor, the plumber may be able to repair the sewer line by inserting a flexible liner coated with resin into the damaged section and inflating it with hot air to seal it in place.

• Replacing the line: If the damage is extensive, the plumber may need to replace the entire sewer line. This involves digging a trench to access the damaged section of the line, removing the old line, and installing a new line made of PVC or other durable material.

• Backfilling and Cleanup: After the new line is installed, the trench is filled back in and the area is cleaned up.

• Inspection and testing: Once the repair or replacement is complete, the plumber will inspect the line and test it to ensure that it is functioning properly.

It's worth noting that some plumbers now offer trenchless sewer repair methods, which involve using specialized equipment to repair or replace the sewer line without digging a trench. This approach can be less invasive and more cost-effective than traditional methods.
