I’m not sure I understand how, in the following case, a CSV reduces the number of cycles. If I had a 40 gallon pressure tank (maybe 20 gallon water capacity), and I drew water say 5 times at 4 gallons each time, the pump would run once. However, with a CSV and the small PK1A which I have, if I drew water 5 times at 4 gallons each time, the pump would run 5 times.
