From all I've been reading, I think we need the CSV1 with small tank, but I want confirmation.
Pump is submersible 3/4HP, new in '97, in 110' well. Pressure tank is original from 1989, Xtrol 203, running 40/60. I just timed the cycle with one garden hose running, and the pump cycle was about one minute on and two minutes off. [Air in Xtrol may be low--haven't checked.]
I filled a gallon jug at the kitchen sink (full force) with no other faucets open, and it took 40 seconds. That is uncomfortably close to the 1GPM the CSV1 needs to keep the pump running. If I didn't have the faucet full open, there could be cycling because I'd be under 1GPM, no? And this may be the same with the garden hose because it's usually not running full open.
Well head is about 120' from house and higher elevation than pressure tank; pressure at hose bib near tank is good.
If I've missed anything in this description anyone wants to know, please ask. Local well men want to sell us a Flexcon-12 pressure tank.
