Far left is bladder tank. Beside the bladder tank, obscured from view, is the softener. In the middle, the white cylinder, says “conditioner”, I would guess it’s something to condition the water aside from the softener tank. I don’t know what the big gray tank is. That’s not an insulation blanket, it’s “wrinkled” gray paint.
Can anyone help identify what the big gray tank may be used for? I’m thinking an additional storage tank, since there’s only 50 pounds of pressure?
