Before use, NFPA 1192 requires potable water tanks to be what?

The requirement for potable water tanks to be sanitized, flushed, and drained is critical to ensuring the safety and quality of the water supply. Sanitization is necessary to eliminate any harmful microorganisms that may be present in the tank from previous use or contamination. Flushing the tank involves removing any residual water and debris that could compromise water quality. Draining the tank ensures that any remaining contaminants are cleared out before the tank is filled with fresh potable water. This process is vital for maintaining health and safety standards in water storage, adhering to the NFPA 1192 guidelines, and ensuring that the water provided is safe for consumption.
