When installing plastic pipe underground, the maximum distance between supports that secure the pipe to the bottom of the trench shall be __________ feet.

In the context of installing plastic pipe underground, the Omaha Plumbing Code specifies that the maximum distance between supports that secure the pipe to the bottom of the trench shall be 8 feet. This requirement is important for ensuring the integrity and stability of the piping system.

When plastic pipes are installed, they can be subject to various external pressures and fluctuating temperatures, which can cause the material to expand or contract. By securing the pipe every 8 feet, it helps to prevent sagging or movement that could lead to joint separation or cracking over time. Proper support is crucial for maintaining the alignment and functionality of the piping, enhancing both safety and longevity.

The dimension of 8 feet meets the codes and standards established to protect infrastructure and maintain service reliability. Following these guidelines helps prevent potential leaks and reduces the risk of costly repairs or replacements later on.
