High water pressure is good, but water pressure that’s too high can damage your plumbing systems<\/a> and appliances.<\/p>\r\n

At United Air Temp, our plumbing specialists can help ensure the force flowing through your pipes is just right by installing pressure-reducing valves. These are installed near the shut-off valve on the main water line to help regulate the home’s water pressure.\u00a0<\/p>\r\n

Contact United Air Temp<\/a> to learn more about pressure-reducing valves and how they will help ensure your home has even, reliable pressure.<\/strong><\/p>\r\n

How Pressure-Reducing Valves Work<\/h2>\r\n

Pressure-reducing valves cause resistance to the water flow. Inside the valve, a spring diaphragm tightens when it senses high pressure. This creates resistance that keeps your water pressure within the recommended 40 to 60 psi (pounds per square inch).<\/p>\r\n

This is important because if water pressure falls below this level, you could experience a low-pressure shower. If it rises above this level and reaches 70 to 80 psi, it can damage pipes, pipe joints, faucets, fixtures, and appliances.<\/p>\r\n

Contact United Air Temp<\/a> to learn why it’s crucial to maintain your water pressure at a steady, consistent level in your home.<\/strong><\/p>\r\n
