What must be indicated on the label for side wall clearance and working pressure?

The requirement for indicating side wall clearance and working pressure on the label is crucial as it directly relates to the safety, functionality, and proper installation of plumbing systems. The side wall clearance provides essential information regarding how much space is needed around a plumbing fixture or appliance to ensure safe operation, maintenance, and compliance with building codes. Working pressure indicates the maximum pressure that a system can safely handle, which is vital for preventing leaks, failures, and potential hazards.

Including this information on the label ensures that plumbers and technicians can refer to it during installation and maintenance, which promotes adherence to best practices and necessary regulations. It also aids in ensuring that the equipment functions effectively within the specified parameters, significantly reducing the risk of malfunctions or accidents. This focus on clear labeling reinforces the overall principle of safety in plumbing practices.
