One key way to judge malfunction of pressure balance elements is by monitoring pressure stability in the system. These elements are designed to maintain consistent pressure, so any unexpected fluctuations may indicate a problem.

Pressure Instability
For instance, if the system pressure suddenly rises far beyond the normal range or drops sharply without obvious external causes, it could mean the elements fail to regulate pressure effectively. This instability might manifest as inconsistent output from downstream equipment, as the unbalanced pressure disrupts their normal operation.
-
Abnormal Noises or Vibrations
Under normal conditions, these elements operate with minimal, steady sound. If there are sudden squealing, grinding, or rattling sounds, it may suggest internal components are stuck, worn, or damaged. Similarly, unusual vibrations—especially those that grow stronger over time—can signal misalignment or deterioration inside the elements, preventing them from functioning as intended.
-
Medium Leakage
Malfunctioning pressure balance elements may develop leaks at connection points or on their surfaces. This leakage can be observed as visible seepage of the medium (such as liquid or gas) around the element. Even small, slow leaks should not be ignored, as they often indicate failed seals or cracks in the element structure. Leaks not only reduce system pressure but also waste resources and may pose safety risks in certain applications.
-
Decline in System Performance
If equipment that relies on stable pressure from the balance elements shows reduced efficiency—for example, slower operation, inconsistent output, or frequent shutdowns—it may be a result of faulty pressure regulation. The elements' inability to maintain proper pressure forces the entire system to work harder, leading to decreased performance and potential damage to other components if the issue is not addressed promptly.
