In order to maintain a set pressure in the structure or reduce the high incoming water pressure, a pressure reducing valve is often installed. While commonly known as a regulator, the pressure reducing valve provides a lower, more functional pressure for distribution to the consumer, thus protecting the water supply system in the process.

Water conservation plays a vital role in sustaining life on Earth. With climate change, a growing population, and increasing demands for water, our freshwater resources are under a lot of strain. Conserving water is not only environmentally friendly but it allows the homeowner to save on their energy bills.


Homeowners and businesses get charged a high rate for both water consumption and the disposal of wastewater. Reducing water consumption lowers this cost and even reduces that excess energy required for heating additional hot water. Traditionally, 50 PSI or less is sufficient inflow pressure for a home or business. This means that any higher pressure may mean water resources wasted. In fact, as much water flows through a system at 150 PSI than at 50 PSI.


A pressure reducing valve can help with water conservation by efficiently controlling and reducing the water pressure within a plumbing system. When water pressure is too high, it can lead to inefficient water use, increased wear and tear on pipes, and even cause appliances to consume more water than necessary. The pressure reducing valve ensures that the required amount of water is delivered at an optimal pressure, minimizing the likelihood of leaks and water loss. This not only conserves water directly by preventing wastage but also indirectly by prolonging the lifespan of the plumbing system and reducing the need for repairs or replacements. In this way, pressure reducing valves contribute significantly to responsible water usage and contribute to the larger goal of water conservation.


As a solution, an A.Y. McDonald Pressure Reducing Valve (PRV) brings the pressure down to a suitable rate, which allows a structure to save on water, energy, and wastewater while giving the entire plumbing system a longer life! Our product options come in multiple sizes, connections and materials that can be customized based on the application on hand.

Too much water pressure or not enough; while the plumbing system does a great job to help homes/structures gain access to water, there’s no saying what the water pressure will be like. Therefore, in the scenario in which there is too much water pressure, you know you can rely on a pressure reducing valve.
