What is a potential consequence of missing or defective pipe hangers in a sprinkler system?

Missing or defective pipe hangers in a sprinkler system can lead to pipe rupture due to inadequate support. Hangers are designed to secure pipes in place, preventing them from sagging or moving under pressure and during fluctuations in temperature. When pipes are not properly supported, stress can build up at joints and connections, leading to leaks or even ruptures.

Additionally, if the system experiences any significant movement, such as from vibrations or thermal expansion and contraction, unsupported pipes can fail more easily. This not only causes damage to the system but can also result in water damage to the building and higher repair costs. While other outcomes, such as reduced water flow and increased maintenance costs, can occur because of related issues, the immediate and direct consequence of having improper hangers is the risk of the pipes breaking.
