I want to ask if any pressure will be lost or will the flow rate suffer if a small reservoir(16mm * 16mm * 2mm) is made in between the inlet of the hose barb and the base plate.
For example,
this. When water enters the block, it enters a small reservoir (which is bigger than the ID of the Hose barb ), before it passes through the jet arrays to the base plate.Or will there be none?
