What is the function of a pressure reducing valve?

The function of a pressure reducing valve is to reduce incoming water pressure to a safe level. These valves are commonly installed in water supply lines to ensure that the pressure does not exceed a certain limit, which can protect plumbing fixtures, appliances, and piping systems from potential damage due to excessive pressure. By modulating the pressure, these valves help prevent leaks, system failures, and prolong the lifespan of plumbing fixtures.

High incoming water pressure can lead to issues such as noisy pipes, leaks, and damage to appliances like washing machines and dishwashers. Therefore, the pressure reducing valve is critical in maintaining system integrity by providing consistent and manageable pressure for safe operation.
