Sample interview questions: Can you explain the process of drain snaking and when it is the most appropriate solution?
Sample answer:
Drain snaking, also known as drain auguring or drain rodding, is a common method used by plumbing professionals to clear clogs in drains and pipes. It involves the use of a tool called a drain snake or drain auger, which is a long, flexible metal cable with a sharp end or a spiral attachment.
When it comes to the most appropriate solution, drain snaking is typically used for clearing blockages caused by organic matter, such as hair, food particles, grease, and other debris that accumulates over time. It is particularly effective for clogs that are located closer to the surface, such as in sink or shower drains, as well as for smaller diameter pipes.
The process of drain snaking begins by inserting the cable into the drain opening, which can be either a cleanout access or a fixture drain. The cable is then pushed or rotated through the pipe, allowing the sharp end or spiral attachment to break through the clog and either push it forward or break it apart. As the cable moves through the pipe, it can also scrape off any built-up debris from the pipe walls, helping to improve overall drainage.
During the snaking process, the technician may encounter resistance or feel the cable turning more difficultly, which indicates the location of the clog. Once the clog is broken up, the cable is slowly retracted, pulling the loosened debris along with it. In some cases, water or a drain cleaning solution m… Read full answer
