What is the minimum spacing requirement for hangers on horizontal 1" CPVC?

The minimum spacing requirement for hangers on horizontal 1-inch CPVC (Chlorinated Polyvinyl Chloride) pipe is 3 feet. This guideline is established to ensure that the pipes are adequately supported, preventing sagging and stress that could lead to damage or failure over time. Proper support spacing maintains the integrity of the piping system while accommodating thermal expansion and contraction.

In the case of CPVC, which can expand or contract with temperature changes, the spacing is designed to allow enough flexibility while still providing proper support. Insufficient spacing could lead to issues such as improper alignment or increased susceptibility to breaking or leaking.

It's crucial to adhere to these spacing requirements to comply with the Massachusetts Plumbing Code, which aims to promote safe and efficient plumbing installations. Understanding and implementing such guidelines help ensure the longevity and reliability of piping systems in various applications.
