Nothing Lasts Forever
Though you might think something as solid and sturdy as a water pump would last until your grandchildren have grandchildren, you would be mistaken in thinking so. Given enough time, pressurized liquids can deteriorate nearly anything, and any included solids would only exacerbate the problem. Any mechanical component with moving parts will eventually become less efficient, and water pumps are certainly not an exception. If it has been several years since the pump was originally purchased, or if it has been damaged or heavily used, then it could be time to consider purchasing a new one. Just be sure to choose the one that best suits your requirements.
Different Pumps for Different Jobs
Much like any other mechanical object, every pump is designed for a very specific purpose, and although there are some that are multi-functional, a pump will work best if it is being used to handle the very material for which it was designed. Pumps designed to handle only water would be insufficient at handling corrosive materials, in which case you want something like a liquiflo mag drive gear pump. There is also the matter of the pump’s function itself, since many of them do not perform the same tasks. A grinder pump would not be used for something that would need to be done by a gear pump, such as the aforementioned liquiflo mag drive gear pump, and the same applies to many other varieties of pumps.
Better Safe Than Sorry
For whatever task you are using the pump, having it fail is something that could be potentially devastating, and possibly result in environmental damage or a personal injury. Whether your old pump is at your place of work or in your own home, you should consider replacing it with something new and fresh, preferably with a money-back guarantee. Only then can you know for certain that old age will not lead to a failure with your pump.
