What is the primary function of the top float on a float tree in a pump tank?

The primary function of the top float on a float tree in a pump tank is to serve as a high-level alarm. This component is crucial for monitoring the liquid level within the tank. When the sewage or wastewater reaches a certain height, the top float activates, triggering an alarm to alert maintenance personnel or homeowners that the tank is nearing its maximum capacity. This helps prevent overflows, which can lead to environmental hazards and costly cleanup.

By signaling when the tank is full, the top float plays a vital role in ensuring the proper function of the septic system. It allows for timely interventions, such as pumping out the tank before it overflows. Understanding the function of the top float is essential for anyone involved in septic system maintenance and operation.
