What must tanks be made to allow for installation and removal from dwellings?

Tanks must be constructed as whole units to facilitate efficient installation and removal from dwellings. Building tanks as whole units minimizes the risk of leaks or structural weaknesses that could arise from joints or seams often found in modular or segmented designs. Whole units are generally stronger and more durable, ensuring that they can withstand the various stresses encountered when being transported in and out of a dwelling.

The design as a single unit also simplifies the installation process, as it requires fewer connections and less assembly on-site, making it both time-efficient and cost-effective. While flexible components or compact designs might offer certain advantages in specific applications, whole units provide the necessary robustness and reliability required for effectively managing any contained fluids or gases within residential settings.
