"In recent years there has been a tendency to treat the pump as a commodity item, not realising it is one of the most important items in the plant room. Old pumps are commonly replaced like-for-like or by one of a similar bore size, and usually higher head. In my opinion this is a recipe for future trouble as most pump failures can be attributed to over-sizing or poor selection.
