What device is recommended to manage high water pressure when installing a water system?

A pressure regulator is the recommended device to manage high water pressure when installing a water system. This device plays a crucial role in reducing incoming water pressure from mains supply to a safer, more manageable level required by the plumbing and appliances in the system.

High water pressure can cause damage to pipes, fixtures, and appliances, leading to leaks and failures. The pressure regulator automatically adjusts and maintains a consistent output pressure, regardless of fluctuations in the incoming supply. This not only protects the integrity of the plumbing system but also ensures that appliances operate efficiently and reliably.

In contrast, other devices such as pressure monitors, relief valves, and switches serve different purposes. While a pressure monitor tracks the current pressure, it does not control it. A pressure relief valve is typically used as a safety device that opens to release pressure in case it exceeds a certain threshold, rather than continuously regulating pressure. A pressure switch operates within specific pressure ranges to control pumps or machines but does not serve to regulate pressure in the system itself. Therefore, for the purpose of managing and regulating high water pressure effectively, the pressure regulator is the correct choice.
