Yeah but its not under any pressure, so ot comes back to the age old ims shower screen debate, unless you are looking at it under pressure in use how do we know how its acting?
One thing about those clips is you need to be super careful with then, that are what the evo originally shipped with and they can be a ball ache to fit, they cant spring out of the pliers and be quite dangerous, i marked the front of my machine with one of these coming free.
Think this is just a case of ££££ talking again,
I remember when people were moaning that the circlip was disturbing flow, so you cant win, one minute thats happening then the next the machine gives 40mls a second so has such a rapid fill it makes no odds 🤷
