How should the hot and cold water flow be arranged on faucets?

The arrangement of hot and cold water flow on faucets typically follows standard plumbing codes and conventions, which dictate that hot water should be positioned on the left and cold water on the right. This setup is widely adopted for consistency and to prevent confusion for users.

Adhering to this convention helps ensure that anyone using the fixture knows that turning the left handle or knob will provide hot water, and turning the right will provide cold water. This is particularly important in public facilities and new installations, where unfamiliar users may not be aware of any particular deviations from this standard.

Ensuring that hot water is on the left also supports safety by minimizing the risk of accidental scalding. This arrangement is commonly observed in residential plumbing systems, fostering familiarity and comfort for those who use various faucets across different locations.
