Which method is NOT a way to damage a pump?

Flushing a hydrant is a routine maintenance procedure used to clear out debris and sediment from the water supply system. It does not involve any conditions that would cause damage to a pump. In fact, flushing hydrants can often help maintain the functionality of pumps by ensuring that they have access to clean water and reducing the likelihood of damage.

In contrast, overheating can occur when a pump runs without adequate cooling, leading to potential failure of its internal components. Wear from debris happens when foreign materials in the water cause abrasion and damage to the impellers and casing of the pump. Cavitation is a phenomenon where vapor bubbles form in the pump due to low pressure levels, which can collapse and cause significant mechanical damage. Each of these conditions can compromise the integrity and operation of the pump, making them true potential damage factors.
