In a real world application, which is a house with a garden hose, heat pump, sprinkler system or the like, Amtrol's lab results would show the devastating cycling that has long been the cause of pump system failures. A worst-case scenario would be a continuous demand of 7.5 GPM. Using a 15 GPM pump with a tank having 15 gallons of draw down as in Amtrol's "study", there would be continuous cycling every 4 minutes. That would be 360 cycles per day or 131,400 cycles per year. It does not matter if the old pressure tank only system saves any energy or not, the equipment would not last long enough to get a good test. Even if these continuous demands were only required 25% of the time that would still be 32,850 cycles per year with the old pressure tank only system compared to 3,000 cycles per year when using a "cycle control valve".
