I'm sure everyone has a crystal ball and knows how to size a pump for every home and for every season. Then there is still the variable versus constant pressure which you have not addressed.If the pump and tank were properly sized in the first place a CSV will have little if any effect on either the longevity or the cost of operation.
My micronizer relies on a certain volume to be forced through a tiny venturi in order to create a vacuum to suck in air. The greater the pressure, the less the differential across the venturi and so the less vacuum. As much as I would like to have 70 PSI in the house, at that pressure the micronizer doesn't suck air. The brand happens to be Waterite.What sort of micronizer wont take a high pressure?
OK, so you say you don't try to discredit, so then you seem overly concerned about how people spend a couple hundred bucks. IMHO it is money well spent and better than spending it on bigger tanks which only prolong the variable pressure. Some folk claim they can't even notice the 20 PSI spread on a standard pressure switch, but I certainly can.
