What is the effect of not utilizing a flexible coupling on a sump cover's suction pipe?

Not utilizing a flexible coupling on a sump cover's suction pipe can indeed lead to situations where the cover cannot be easily removed. A flexible coupling is designed to accommodate movement and misalignment between connected pipes. Without it, any expansion, contraction, or vibration in the pipes can create stress on the connections. This stress can potentially cause components to bind or seize, leading to situations where the cover becomes difficult or impossible to remove.

A flexible coupling provides the necessary flexibility to handle such movements, ensuring that the connections remain functional and that maintenance tasks, such as cover removal, can be performed without obstruction. The importance of this flexibility in maintaining ease of access to the sump cover highlights why the absence of a flexible coupling could present challenges in operations and maintenance.
