How often should hard drawn copper tube and annealed copper tubing be supported vertically, at not more than ___ ft. intervals?

The correct answer is: 10

The correct answer regarding the vertical support requirements for hard drawn copper tube and annealed copper tubing is 10 feet. According to the Illinois Plumbing Code, copper tubing must be adequately supported to prevent sagging, stress, and potential damage over time. The standard interval for vertical support is established at a maximum of 10 feet. This spacing helps maintain the structural integrity of the piping and minimizes the risk of failure due to inadequate support. Options with shorter intervals, such as 5 or 8 feet, may suggest a higher frequency of support than necessary for typical applications involving coppers. Alternatively, a supportive interval of 12 feet exceeds the recommended spacing, which could lead to issues with sagging and instability in the installed piping system. Adhering to the 10-foot requirement efficiently balances both support and practicality in installation.
