Given a hydronic system running at 150 psi and rated to run at 115 psi, what is the maximum pressure it should not exceed?

In a hydronic system, the maximum allowable pressure often corresponds to the system’s safety ratings and its design specifications. When a system is rated to run at 115 psi, this indicates the level at which it is designed to operate safely under normal conditions. The reference to running at 150 psi suggests that the system is currently under higher pressure than its rated capacity.

The correct answer, which suggests that the maximum pressure the system should not exceed is 150 psig, reflects the importance of maintaining operational parameters within safe limits. Operating at or below the rated capacity of 115 psi is ideal for optimal function and safety. Exceeding this by a substantial margin, as in the case of 150 psi, can lead to increased risks of failure or safety breaches, but it is within the bounds of short-term operational tolerance, based on the context provided.

If a system requires a pressure rating or maximum tolerable limit, it’s crucial to observe safety protocols and standards to prevent possible catastrophic failures. This is why the emphasis on not exceeding the 150 psi threshold is significant; exceeding it may not be advisable or safe based on the rated capacity and risk factors. The other choices proposed higher pressures that would likely push the system beyond safe operational limits, demonstrating
