Are you sure you guy's don't have the varistream 2.5 version, it changed from v2 to v2.5 when they changed the switch, and this was the only reason they upgraded to the 2.5.
I may be wrong but did not know they had a v3 out, unless its new stock and they have labeled it v3.
Does anybody have one of these yet and what do they think of it,there supposed to be pressure switch freindly.I have read that with these there is next to nothing that can go wrong and there is no need for a pressure switch.Essentially Pure also have an ECO 2 coming out soon that performs the same.
You by-pass and do away with the pressure switch, when you fit a varistream.
The pure freedom one, I believe will be a sealed unit, there is no way moister can penetrate the unit, but if any thing goes wrong with it, you have to send it back.
