Are any of my pumps grossly oversized?
Here is the latest schematic of what I plan to do. I would appreciate any comments. The drawing is to scale. I have 1" going to the Hot water heater and most of the primary and seconday is 1-1/4".I sized circulator pumps so that I have a range of 5-6-1/2 GPM on all zones.
