Well and bladder tank issue

[crucible]

Their animation shows it working a bit differently but it isn't important. The pump kicks on at the low setpoint and the CSV maintains some intermediate pressure until the demand stops and the pressure reaches the high setpoint.

My main problem is excessive pressure drop when using two devices. I may just have more restriction in my water treatment than you do; which is why I'm thinking a second tank and/or a tighter deadband might be better for me. I still have some thinking and observing to do.

FWIW, I saw a few instances where the "owner"/creator recommended a CSV and a larger pressure tank (instead of the standard 4.5g) to solve some specific non-standard problems....perhaps this may be applicable to your situation. They seem to be responsive to inquiries.....
