ACS Evo2 Lever - new flush lever

Main review website: coffeeequipmentreviews.wordpr...
The flush lever is primarily to allow the group to be flushed clean between shots. There are some side benefits though:
A bloom phase (wetting the puck but no pressure during the pause shot). Achieved by engaging the flush lever for a few seconds and pausing (the preinfusion timer will start). Waiting some seconds, then pulling the lever down for the normal PI and shot phase.
The revision of the first flush lever to try and achieve variable pressure. It doesn't really do that (yet), however it does open the water valve earlier, giving a larger swept volume, potentially larger shots, although the group holds plenty really. With the safety system, it eliminates the need to precharge for high pressure shots, although doesn't yet allow adjustment for those low pressure shots if you want them.
Waiting for a 3rd version that might well work to give variable pressure.

Great to see another video from you!

Looks great! Just out of curiosity. What makes you like higher pressure shots? And do you get a lot of channeling when you make them?

I see you have given up the deioniser. I haven't found it makes much difference since I changed grinders to the Eureka Oro SD.

What grinder is that?

Couldn't you solve the problem by making the Teflon slider in a wedge shape so a smaller movement would make a bigger change?
