Check for Leaks and Verify Operation

What happens here

After the cement has been applied and the joints have had a moment to set (though full curing time is not shown), the creator tests the repaired sump line by running the sump pump. He visually inspects the newly joined sections for any leaks. He then confirms that the water is successfully pumping out of the discharge end of the pipe, indicating the repair was successful and the line is no longer clogged.

Goal: Ensure the repair is watertight and the sump line functions correctly.
