When testing the high-level setting of an altitude valve, what should you monitor?

Monitoring the tank water level when it is being filled is essential when testing the high-level setting of an altitude valve because it allows you to observe if the valve is functioning as intended. The altitude valve is designed to control the water level in the tank by opening and closing at predetermined levels. By focusing on the water level during the filling process, you can ensure that the valve properly senses the rising water and responds accordingly to prevent overflow.

If the valve is set correctly, it should close before the water level reaches the maximum set point, thereby maintaining the tank’s capacity without excessive overflow. Observing the water level during filling provides real-time feedback on the performance of the altitude valve, allowing for necessary adjustments to be made.

Other factors related to the water distribution system pressure or observations during the emptying process are not as relevant for testing the specific functionality of the high-level setting. Additionally, while the flange float assembly is related to the operation of the altitude valve, monitoring the tank water level during filling is a more direct indicator of the valve’s effective performance in preventing overfilling.
