What is the maximum flow rate allowed for showerheads in new installations?

The maximum flow rate allowed for showerheads in new installations is set at 9.5 liters per minute. This standard is established to promote water conservation and efficiency in plumbing systems, aligning with sustainability practices. By limiting the flow rate, the National Plumbing Code of Canada aims to reduce overall water consumption without compromising user experience.

A maximum flow rate of 9.5 liters per minute is a balance that allows for adequate water pressure and performance while encouraging responsible water use. This is particularly important in the context of modern plumbing, where efficiency and environmental concerns are increasingly prioritized. The other flow rates mentioned, such as 5.0, 7.5, and 11.5 liters per minute, do not meet the regulatory standards set for new installations, which is why they are not applicable in this context.
