Frequently Asked Questions About Pressure Reducing Valves
What is a Pressure Reducing Valve (PRV), and what is its primary function?
A Pressure Reducing Valve (PRV) is a plumbing device designed to control and reduce the incoming water pressure from the main supply to a safe and manageable level within a building. Its primary function is to prevent excessively high water pressure, which can cause damage to plumbing fixtures, pipes, and appliances, ensuring a consistent and safe water supply.
When is it necessary to install a Pressure Reducing Valve in a water supply system?
PRVs are typically installed in properties with water supply systems that have excessively high water pressure, which can vary depending on local conditions. High water pressure can damage pipes, fixtures, and appliances and lead to water waste. If you experience issues like burst pipes, dripping faucets, or water hammer (noisy pipes), it may be a sign that you need a PRV to regulate and maintain a safe and consistent water pressure.
How do I install and maintain a Pressure Reducing Valve?
Proper installation of a PRV requires placing it in the main water supply line and adjusting it to the desired pressure setting. Maintenance involves periodic checks to ensure the valve is functioning correctly. This includes inspecting for leaks, adjusting the pressure as needed, and cleaning or replacing the screen or filter to prevent debris buildup. It's advisable to consult a professional plumber to ensure the PRV is installed and maintained correctly to protect your plumbing system.
