  1. Shut off the gas supply. Inspect the broken section of the gas pipe and remove it. Measure the length needed for replacement. Cut a new 1/4" aluminum tubing to size, and use compression fittings to secure it in place. Ensure all connections are tight and check for leaks using soapy water before restoring gas supply.

  2. If the damage is severe or the pipe is inaccessible, consider replacing the entire gas line. Shut off the gas, remove the old line, and install a new one following local codes and regulations. Make sure to test for leaks after installation.
