How do you know if your Pressure Reducing Valve – PRV valve is bad?

February 5, 2024

In a whole house pressure system, the Pressure Reducing Valve (PRV) plays a crucial role in maintaining a safe and controlled water pressure throughout your plumbing network. However, like any mechanical component, PRV valves can deteriorate over time, leading to potential problems. This article will explore how to identify signs of a faulty PRV valve, its average operating time, and the consequences of neglecting its maintenance. Additionally, we will discuss the recommended pressure levels for plumbing fixtures and provide guidance on checking and adjusting your PRV valve.

Average Operating Time:

PRV valves are designed to last for several years, but their lifespan can be affected by factors such as water quality, system usage, and maintenance. On average, a well-maintained PRV valve can operate effectively for 10-15 years. Regular inspections and preventive measures can significantly extend the life of the valve.

Consequences of a Faulty PRV Valve:

Water Heater Failure:

One of the primary consequences of a malfunctioning PRV valve is increased water pressure. Elevated pressure can put excessive strain on your water heater, leading to leaks, burst pipes, and premature failure of the heating element. Regularly checking and maintaining your PRV valve can prevent such issues and extend the life of your water heater.

Potential Explosions:

When water pressure exceeds the recommended levels, it can lead to catastrophic consequences. Pipes, fixtures, and appliances connected to the plumbing system may be at risk of bursting or exploding. This not only poses a significant safety hazard but can also result in costly damages to your property.

Recommended Pressure adjustment:

Plumbing fixtures, including uplines and downstream appliances, are typically designed to operate within a pressure range of 60-80 psi (pounds per square inch). Exceeding this range can lead to the issues mentioned above. It is essential to maintain pressure within the recommended limits to ensure the longevity and proper functioning of your plumbing system.

How to Check and Adjust the PRV Valve:

Visual Inspection: Begin by visually inspecting the PRV valve for any signs of leaks, corrosion, or physical damage. Ensure that the valve is properly installed and that all connections are secure.

Pressure Gauge: Attach a pressure gauge to a faucet or hose bib downstream from the PRV valve. This will help you measure the current water pressure in your system.

Replacement: If the PRV valve is severely damaged or cannot be adjusted within the recommended range, it may be necessary to replace the valve. Consult a professional plumber for assistance if needed.

Conclusion:

Regular inspection and maintenance of your PRV valve are crucial for preventing potential disasters associated with high water pressure. By understanding the average operating time, consequences of a faulty valve, and recommended pressure levels, homeowners can take proactive measures to ensure the safety and efficiency of their whole house pressure system. Always refer to the manufacturer’s guidelines and seek professional assistance if you encounter any issues with your PRV valve. Remember, a small investment in maintenance can save you from costly repairs and potential hazards in the long run.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.

United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
