Understanding the Navien Tankless Water Heater Knocking Noise
If you’re experiencing a knocking noise from your Navien tankless water heater, it could be due to a few different causes. One potential culprit is loose or damaged components within the unit. This might include pipes, valves, or other internal parts that are rattling around and creating the noise. Another potential issue could be related to water flow and pressure. If there are irregularities in the flow or pressure, it can create vibrations and knocking sounds as the water moves through the system.
Lastly, the water hammer effect could be at play. This occurs when the flow of water is suddenly stopped or changed direction, causing a shockwave and resulting in the knocking noise. By evaluating these potential causes, you can determine the source of the issue and take the necessary steps to address it.
