Blows the gasket a lot quicker than without the restrictor though.

This is much more fun for us who can play "theory" since we don't have to get wet and dirty (as the actress said to the bishop). [img]/ubbthreads/images/graemlins/grin.gif[/img]
However, I still maintain that the pressure is not regulated by the size of the shower-head holes if the restrictor is letting more water through than the head can expel. The best that you can hope for is that the pressure build-up at the shower head will be SLOWED, but EVENTUALLY if the shower lasts long enough the pressure at the head will equalize with the pressure before the restrictor and still end up blowing your seal, as you have discovered.
OK, thats the fun theory out of the way. Actually, I think that you just have a dud shower head.
