What is a common consequence of not ensuring proper draft while pumping?

Focusing on the consequences of not ensuring proper draft while pumping, it is crucial to understand that a pump relies on a consistent and adequate supply of water to function efficiently. When the draft is inadequate, the pump may struggle to maintain an optimal flow of water, which can lead to excessive strain on its components. This can cause the pump to overheat due to the increased friction and resistance within the system as it attempts to draw water that isn't readily available.

Additionally, overheating can lead to mechanical failures or damage to the pump itself, which could result in costly repairs and downtime. The implications of pump overheating stretch beyond just mechanical integrity; it compromises the overall effectiveness and reliability of the pumping operation, which is critical during emergency situations.

The other options presented, while they might seem plausible, do not accurately capture the primary risk associated with poor draft. Proper draft is essential for maintaining operational efficiency and safety, and neglecting it primarily increases the risk of pump overheating.
