The discharge piping from a temperature and pressure relief valve should terminate not more than 6 inches above the floor to ensure safety and accessibility. This height ensures that any water or steam discharged will not create a hazard, such as causing burns or flooding the area. Additionally, having the pipe terminate at this specified height allows for proper drainage without the risk of the discharged fluids pooling or causing damage to surrounding structures. The choice of 6 inches is based on industry standards set forth in the plumbing codes, which aim to prevent injury and maintain sanitary conditions. Proper termination height is essential for the effective functioning of the relief system, ensuring it operates safely during times of relief activation.
