The discharge piping from a temperature and pressure relief valve shall not terminate more than ____ inches above the floor.

The discharge piping from a temperature and pressure relief valve must not terminate more than 6 inches above the floor to ensure proper functionality and safety. This requirement is in place to prevent the discharge from creating a hazard, such as splashing or causing burns if the fluid is hot. Additionally, it allows for better visibility and accessibility for maintenance, making it easier for personnel to observe any discharges and respond appropriately. Keeping the discharge piping within this height facilitates effective drainage away from the appliance, reducing potential for water damage or health risks associated with accidental contact.
