TBH, I’ve got pretty low water pressure where I live. Low-flow shower heads are bullshit, and I would much, much rather have the bad, old, inefficient, high-flow shower heads, and a decent amount of water pressure. High efficiency toilets, washing machines, dishwashers, etc. are great. But dammit, I just want to shower under a high-pressure firehose, at temperatures that will boil my skin off in ten minutes!
