What should be done if high water temperatures are detected in a system?

When high water temperatures are detected in a system, adjusting the thermostat settings is essential to ensure that water is maintained at safe levels. High temperatures can lead to conditions that promote the growth of Legionella bacteria, which thrive in warm water. By adjusting the thermostat, you can lower the temperature and help to mitigate the risk of Legionella proliferation.

This proactive step is vital for maintaining a safe plumbing system and ensuring the health of users. Additionally, it is a more efficient and straightforward solution compared to the other options, which may not directly address the root cause of the high temperatures. For instance, increasing water flow might temporarily alleviate issues in some scenarios but does not resolve the underlying temperature concern. Installing additional heating elements could exacerbate the problem instead of fixing it, and bypassing the system could lead to significant safety and operational issues. Adjusting the thermostat is a targeted approach that addresses the immediate concern effectively.
