Just found out that there is another solution between having a 3-way-valve and no 3-way-valve:
A separate magnetic walve! That's what my ECM Casa II comes with.
On the picture it's that black thing on the left side on the boiler. The longer thing on the right next to it is the over-pressure limiter, where the fresh water comes in from the pump, if the water reaches over 9 bar, part of it flows back to the water tank (so you can't kill the pump using a blindfilter letting the pump run and run).
When you stop brewing, the magnetic walve opens and the water from the portafilter can flow back to the tray, just like with an ordinary 3-way valve.
I think this system would solve your "problem", Andy, since there are 2 separate "routes" for fresh water and backflush-water.
Has anyone seen this technology elsewhere? Is this new?
Seems like a better way to plumb things compared to the usual 3-way valve. I have heard of a somewhat similar system being used elsewhere, but I've never seen a photo of it. Thanks.
