Ah gotcha, I see where the confusion came from then. I wasn't considering the hypothetical scenario where he magically increases water pressure but instead thinking about what will happen in reality when the legislation allows people to get higher flow shower heads (and imagining some of them might be disappointed when it feels less forceful, though I'm sure plenty would enjoy an increased flow if that's their preference). His talk about pressure is a stand in for the actual details of the EO which is actually about low flow fixtures (and I assume low gallon per flush toilets but I didn't read that far).

I admit I was thrown off trying to figure out what we were saying differently, I'm sure I could be more specific though about the hypothetical I was describing. I did a solid semester in multivariate calculus just solving flow equations so it would bring great dishonor to my teacher if I mixed anything up haha.
