What is the maximum flow pressure for certain models of flushometer valves?

Flushometer valves are designed to operate effectively at specific flow pressure levels to ensure optimal performance and water conservation. The maximum flow pressure for certain models of flushometer valves is typically set at 25 psi. This pressure threshold allows the valve to function efficiently, providing adequate flushing power without causing water waste or system stress.

Operating flushometer valves at pressures higher than 25 psi can lead to issues such as excessive noise, water hammer, or even malfunction of the valve mechanism. Conversely, pressures below the maximum requirement might result in inadequate flushing, which can compromise sanitation in restroom areas. Therefore, understanding the correct maximum flow pressure is essential for the effective installation and maintenance of these devices.
