No, the air pumps and water pumps will run for years and years as long as you keep the filters clean. Once a week, you need to brush the water filter off. For the air pumps, there is a filter on the bottom that needs to be removed & cleaned every few months. One reason that people have problems with water pumps is that they are on timers. Timers will wear out the pump by starting & stopping all the time. Our systems do not use timers.
