Which of the following is used for off hour calls as a quick and simple remedy for many?

• A. Flushing
• B. Sewer ball
• C. High velocity cleaning
• D. Bucket machine

Answer: (C)

When a problem hits after hours, you want a method that can quickly restore flow with minimal setup. High-velocity cleaning does this by using high-pressure water jets to scour the inside of the sewer, breaking up grease, scale, and root intrusion, and then flushing the debris out. This single approach often clears a wide range of common blockages, allowing crews to remedy many issues quickly without resorting to digging or major repairs. It’s versatile across different pipe sizes and conditions, and it can be mobilized rapidly to bring service back online.

Flushing, while useful for moving loose debris, isn’t as reliable for stubborn blockages or grease buildup. A sewer ball is primarily used to temporarily seal or divert flow rather than to clear a blockage. A bucket machine is less versatile and slower for addressing the typical range of line problems encountered off-hours.
