What is the maximum spacing allowed for support hangers on horizontal conductors?

The maximum spacing allowed for support hangers on horizontal conductors is 10 feet. This specification ensures that the conductors are adequately secured and supported to prevent sagging or damage over time. Proper support is crucial for maintaining the integrity of plumbing systems, as it minimizes the risk of strain on joints and connections, which can lead to leaks or failures.

Maintaining a 10-foot maximum spacing between support hangers also aligns with industry standards to accommodate for thermal expansion and contraction, which can occur in piping materials under varying temperature conditions. In turn, this spacing contributes to the longevity and reliability of the plumbing installation.

Other options provide distances that are either too short or too long, which could compromise the support and stability of the conductors. Thus, adhering to the 10-foot maximum spacing requirement is essential for both safety and compliance with the Massachusetts Plumbing Code.
