I started reading your comment and was going to add something about how I always see a deep misunderstanding of Bernoulli's principle and... Well you have the same misunderstanding.

Increasing pressure, with no other changes, absolutely changes flow rate. Bernoulli's principle that effectively states as flow increases, pressure decreases (and vice versa) when the source is not changed. If the pressure at the source is increased and the flow rate is the same, then the entire system has more energy. Since the bottleneck is more likely to be the miles of pipes and hundreds of bends, flow rate can't really be inherently increased but pressure can. I, in no way, am endorsing this EO or the insanity surrounding it.

The proper application of the principle is at the outlet with a steady source. It's best explained with a multi-setting garden hose. This is because the variable restrictor is exactly at the outlet. You can choose the stream setting which is high velocity but low flow rate - a single stream shoots across the street. You can choose the shower setting which is low velocity but high flow rate - a wide stream that only travels a few feet away. However, if you try to fill a bucket, you'll likely find they fill at nearly the same rate, allowing for minor differences in nozzle drag and assuming the stream doesn't cause too much drag (like a 1/8" outlet rather than a pin hole). Why? Because the system energy is the same, say 40psi with ample water supply for a garden hose where the faucet and preceeding piping is the restrictor rather than the outlet. At any point prior to the outlet, the pressure is the same and any setting would fill a very tall column to the same point at which pressure from the column equals pressure form the hose. So yes, realistically, bumping up the pressure would result in greater flow at the outlet, just as enlarging pipes, smoothing bends, and swapping high flow valves.

But this is fucking batshit because the pressure has not been reduced and it's not like we just have pumps we can tune to any pressure. The primary source is simply the height of water towers - the water towers that have been here for decades already. The most logical explanation I can give is the slow market change to high efficiency devices. But I'm gonna stick to the thought that the believers are retconning their memories. I mean, the fucking Simpsons have a scene where Bart fluctuates the shower temperature with just the sink faucet. Season 12, episode 12, Tennis the Menace, aired 2001.

Your expat acquaintance couldn't fix the situation because he wasn't addressing the choke points. So many possibilities. Shitting routing in the house, shitty rerouting after a renovation, mineral deposits inside older pipes, longer routing in modern houses that are bigger with more bathrooms, false memories of the "before times" invented by Trump's rambling, insufficient infrastructure as neighborhoods expand, or poor delivery system maintenance. Friendly reminder that there is a non-zero number of people buying into this while using household wells.

This is another case of completely misusing words with the implicit "you know what I mean" attached. The truly insincere thing about this method is that because everything it says needs interpretation everything it says is interpreted in the most convenient ways for those with the power to choose which interpretation they prefer.
