What condition in a wastewater pumping system can indicate a clogged discharge line?

In a wastewater pumping system, a clogged discharge line is typically indicated by high discharge pressure. When there’s a blockage in the discharge line, the pump continues to work harder to push the wastewater through the line, leading to an increase in pressure. This spike in discharge pressure can stress the system, and if it remains elevated, it can eventually cause damage to the pump and other components.

The other conditions, such as an overheating motor, unusual vibrations, and excessive noise, may arise from various other issues within the system. While some of these symptoms could potentially be linked to a clog, they do not specifically point to a clogged discharge line as directly as high discharge pressure does. Thus, monitoring discharge pressure can be a key indicator for operators to identify potential clogs in the system effectively.
