Understanding Pressure Reducing Valves: Save Your Time and Efforts

When household issues come up in 78617, Austin, Texas, property owners need an immediate resolution. One of the most common issues a property owner can face is a malfunctioning pressure reducing valve (PRV). A PRV is a plumbing device that maintains the pressure of the water in the pipes at a certain level, usually lower than the pressure of the water from the source. This flow control device is an important component of a plumbing system as it prevents certain problems from happening due to over-pressurization. As such, when a pressure reducing valve stops working, quick and proper maintenance action should be taken immediately to ensure the system functions properly. In this article, we discuss the basic principles of a PRV, its benefits to a property owner and other related aspects.

What is a Pressure Reducing Valve?

A pressure reducing valve is a control device designed to lower the pressure levels in water pipelines. It is installed at various points in the system to prevent over-pressurization and to protect the plumbing pipes, fixtures, seals, and other components in the system from damage risk. For a PRV to work correctly, it must be adjusted according to the water pressure levels available in the plumbing system.

How Does a Pressure Reducing Valve Work?

At its most basic, a PRV works by regulating the pressure coming into the plumbing system from the water supply. The PRV is designed to open or close in order to reduce or increase the pressure based on the specific requirements of the system. A PRV consists of several mechanisms such as a pressure-sensing chamber, a relief port, a pilot line, and an adjustable spring-loaded disc. It also has an inlet and outlet port to allow water to flow.

The pressure-sensing chamber contains a diaphragm that moves in response to the pressure changes in the flow. This movement of the diaphragm causes a pressure variation, which is sensed by the pilot line and transmitted to the adjustable spring-loaded disc. Based on the pressure signals, the disc adjusts its opening or closing position to regulate the pressure in line with the predetermined setting.

What Are the Benefits of Using a Pressure Reducing Valve?

A pressure reducing valve provides numerous benefits to property owners. It helps maintain system performance by ensuring consistent pressure in the pipes. This prevents large water hammer effects and aiding in preventing pipes and other components from damage. Additionally, PRV helps avert energy losses due to friction that occur when the water flow is faster. This ensures the system works with maximum efficiency and thus leads to cost savings as well. Lastly, the valve also maintains the health and safety of the plumbing system.

When Do You Need a Pressure Reducing Valve?

Under normal circumstances, if the city water supply has a pressure lower than the required psi value of the plumbing system, a PRV is not needed. However, if the water pressure is higher than the set psi value, it is best to install a pressure reducing valve. This ensures that the system operates normally and also prevents the risk of damage to pipes, fixtures, fittings, and other components in the system.

How to Select the Right Pressure Reducing Valve?

When selecting a pressure reducing valve, it is important to consider the psi value of the water supply. This value is determined using a water pressure gauge that can be inserted between the water supply and the pressure reducing valve. After determining the psi value, the valve should be selected accordingly to maintain the design pressure that has been set for the system.

Maintain Your Pressure Reducing Valves

Keeping a PRV properly maintained is important to ensure it operates correctly. Regular checkups and tests should be done to detect any problems before they become serious. Additionally, it is also important to check the pressure settings from time-to-time and make changes as needed. This helps to prevent unexpected pressure changes in the plumbing system.

Installation, repair, and maintenance of a pressure reducing valve should always be done by a licensed professional. It is highly recommended to contact a local plumber to get the job done correctly and ensure the longterm performance of the plumbing system.
