Some update: I tested the distros that Andy sent, and they are dead silent at 100% pump pressure, and really well machined so Im really proud. They will come with protective foil.
One bad thing tho: I stuggled a lot with finding black screws for the distro, that are actually stainless. Its harder than it sounds. I run through a lot of it, and none of them worked really well, somehow all of them got rusted after a couple of days. Tried Chinese ones, but the black color of the screws looked washed out and very unevenly spread in the surface. There are a couple anodized ones for 0.5euro/piece, that are way too expensive, considering more than 20 needed for one distro. So we gonna use regular stainless steel screws to prevent rusting. Sorry about that, but currently that the only safest way. It can be easily swapped out in the future, if needed, while the pump running. I tested it, and one by one, I can change all of the screws without leaking
