Product Overview
The water flow servo valve is a critical component in Rinnai tankless water heater systems. It precisely meters the volume of water flowing through the heat exchanger, allowing the unit’s control board to modulate burner output and deliver accurate outlet temperatures. When this valve fails or degrades, symptoms can include fluctuating water temperatures, error codes, or complete loss of hot water. Replacing it with a genuine Rinnai OEM part restores factory-specified performance.
