The flow through this is much faster than my old one, I find it a little weak. It literally takes 5 minutes to fill the tank where the old filter took over an hour. Also, my espresso machine has a lot more minerals than it used to, so I think it's not working properly. While it's obvious which way to put it, I've still tried flipping it, dammit, and nothing has leaked out, so I know it's going in the right direction.
