What is the term for two changes of direction installed in succession in a continuous pipe?

The term for two changes of direction installed in succession in a continuous pipe is commonly referred to as a double offset. This terminology is used in plumbing to describe a configuration where a pipe makes two bends in succession, rather than just a single bend.

Double offsets are important in plumbing to navigate around obstacles or to change the direction of the piping system while minimizing the amount of space used and maintaining proper flow. By using two changes of direction, the plumbing system can be adjusted to fit specific layouts without causing detrimental impacts on water flow, pressure, or the overall drainage effectiveness.

In plumbing design, understanding configurations like the double offset helps plumbers create efficient systems that adhere to codes and ensure optimal function. This concept is critical for maintaining effective drainage and preventing issues such as clogs or blockages that may arise from improper pipe angles or layouts.
