Why are there so many loopholes in every single US law? Everytime there’s a major health issue or anything extremely anti consumer it’s because of a loophole in the formulation of a US law. Are US lawmakers that bad? Or is it judges who interpret laws literally instead of using the intent?

There are often fairly sensible reasons or good intent behind many of them. People don't normally drink hot water; it's not a great idea, as it has higher levels of dissolved solids and higher risk of contamination by organisms (like legionnaires). Meanwhile, lead helps make metals and solders more resilient to high temperatures and fatigue at low cost. Banning lead from the hot side could therefore decrease reliabil…

> legionnaires

Actually, this is famously caused by having water that’s not hot enough. It became a problem in some countries when they advised lowering boiler temps to save energy.

Is this actually a thing? I know there are videos of watwr hammer on youtube (US centric) There are no regulations afaik in Europe in domestic = no-industrial plumbing and sure we have quarter valves which you can quickly turn off. I never ever heard of a bursting pipe because of water hammmer.

I am a plumber and sprinkler tech (nyc) and literally have never seen a broken pipe that could reliably be traced to water hammer damage. Really would only be concerned if you are building fire safety systems. Now those sudden GPMs need some support.

I had a problem just this past summer hooking up a pressure washer to a hose outlet. After two hours of constant on-off cycling, had the pipe leading to the hose bib burst. You could hear the water hammer quite clearly (and violently!) after I repaired it, so I went back and added a hammer arrestor.

IDK, they said "a terrible way to make tea ", I'm assuming there's some sorta tea lore that I'm unaware of

There are tea drinkers that believe very strongly in using water that isn't "stale" (eg, leftover in the kettle from the last time). Presumably water from the hot water tap would be stale for similar reasons. I think the theory is that "stale" water lacks sufficient oxygen for tea brewing to fully brew or something.

Fill a cup with cool water and take a sip before you go to sleep. Tastes great, right? Taste it eight hours later when you get up in the morning. It takes on an acrid taste.

The car and its consequences has been a disaster for society. Even today we are pumping so many toxins in to the air to deliver a slower, less efficient, and more expensive form of transport. And it's not a problem that EVs or self driving cars can solve since a huge amount of the pollution comes from tires.

In lots of places the tailpipe emissions of a modern car are cleaner than the air. CO2 is a pollutant, but it's not a toxin when the concentration is low and oxygen is available.

That conveniently ignores the non-tailpipe emissions, for example dust from tires and brake pads. I also suspect that it's only true in the lab, I have the pleasure of cycling through many clouds of noxious soot from supposedly modern cars whose owners just happen to press the throttle harder than what the NEDC requires.

Are there? It seems like plastics are shaping up to be the modern day lead.

Lead roofing tends to get recycled into bullets in time of war, but those roofs that don't, are typically there forever (400+ years) and never leak. Some plastics are UV resistant due to additives but even copper struggles to compete with lead as a roofing material. You only need to look back to the 1970s to find PEX water piping and the disaster/flooding it can cause due to age.

Hopefully you don't have a fire....See: Notre Dame

Try vacationing a couple of weeks in a city that isn't build around cars and has good public transport, maybe you'll understand. Tokyo is nice for example. Note that there still are cars in Tokyo, nobody is banning cars.

In particular I would recommend the ELEY Garden Hose

Eley makes really good (but expensive) stuff. It bugs me that they moved their production overseas though. I could understand if they were selling a $5 sprayer or $15 hose reel. I think they could still make a good profit if their stuff was made back in Nebraska.

Water Right is about a third of the cost. I've left mine out in the sun for three years for one hose, four for the other. The 4 yo one is just started to get a hint of bleaching this year.

This feels like a good time to bring up the lead-crime hypothesis (flaws and all). For those who don't know, there's a strong (if faulty) correlation between lead levels in preschool children and crime rates: https://www.vox.com/2016/1/14/17991876/crime-drop-murder-lea... https://en.wikipedia.org/wiki/Lead%E2%80%93crime_hypothesis Regardless of what you think about the hypothesis, the growth and crunch in lead levels…

I remember reading somewhere that lead exposure might correlate with poverty. Is this accounted for?

It does correlate, and it is accounted for. We have evidence to believe the causal arrow points lead=>poverty. This is because the natural experiments of phasing out leaded gasoline in different countries at effectively randomized times produce subsequent decreases in lead poisoning (and downstream crime). This is as close to a controlled "give one population lead poisoning" experiment as you can ethically run.

And water is essential for life, so that must mean it’s impossible to drown, right?

Funny that people who say things like this and “CO2 is only 0.04% of the air” don’t want to try injecting 0.04% of their blood volume of hydrogen cyanide and seeing if such a tiny amount of something can have an effect…
