What is the maximum length for flexible fixture supply lines?

The maximum length for flexible fixture supply lines is 30 inches. This standard is put in place to ensure that supply lines maintain proper functionality and reliability. Longer supply lines may introduce increased potential for kinking or damage, which could lead to leaks or failures over time. Additionally, using the specified maximum length ensures compliance with plumbing codes that aim to maintain safety standards in plumbing installations. By adhering to the 30-inch limit, plumbers can ensure that installations are effective and less susceptible to future issues, which is essential in both residential and commercial settings.
