While plumbing with single stacks was being installed throughout Europe, Miami was attempting to do the same in the 1990s but instead with proprietary products that begin gaining a reputation for flooding condos with sewage.

I knew getting to and from the train station was going to be annoying but the infrequent bus service made it even worse than I imagined, in addition to weird station locations and no card payments.

I replaced the galvanized iron piping in my house with PEX, introduced to North America in 1984. My water is no longer rust-colored, doesn't taste terrible, and flows much better. It was significantly less work to install the PEX as it was to rip out the old galvanized

Social media loves talking about how everything is getting worse. But what’s something that you’ve seen get _better_ in your lifetime?

The U.S. Department of Commerce published a report in 1951 to support an effort to create a harmonized code for all 50 states. In 1955, ASME published the A40.8 National Standard Plumbing Code as an American Standard Association (predecessor to ANSI) publication.

These are the factory jobs Americans actually want. In addition to helping solve a critical housing shortage, removing the expectation of working outside in the elements would also open the construction trades up to people that never otherwise considered it.

This mini-doc from DW on modular residential construction talks a bit about the recent industry failures in the US and pinpoints inconsistent building codes as one of the major barriers. Interestingly, this issue was also highlighted by HUD’s Operation Breakthrough in the 1960s and 1970s.

I’d buy an abandoned apartment building and fill it with plumbing systems designed in accordance with German or Dutch building standards (highly illegal in the US) and run experiments to demonstrate superior performance. I’d pay for flights/hotels to bring every inspector in the country to see it.

question for the audience: if you were ultra rich (let’s say $25M), what completely frivolous thing are you buying?

It’s an East/West divide between the pedestal and squating WC that persists today. Squatting WCs were produced in France in the mid 19th century when plumbing was still a rare luxury and predates the siphonic WC now ubiquitous in the US. They worked well and are the only early WC still common today.

deep thoughts with Katie Zacharia: "I remember thinking, 'How is China the next country on the horizon? They don't even have proper toilets!'"

I wonder what this map would look like if we had more rational plumbing codes that didn’t represent such a cost barrier. Another part of this story is the cost of traditional wastewater disposal methods for non-sewered sanitation (i.e. septic tanks), which are also unviable in many areas.

The insistence on using SI over AI is a clear attempt to obfuscate another war the US has been waging and losing for over century against the Système international d'unités, costing Americans between $1.603 billion to $2.506 billion per year.

“The sewer gas does not come pouring into everyone’s homes in Philadelphia nor does it happen in Paris.” The single stack isn’t experimental or even radical. It’s in the homes of hundreds of millions of people worldwide and doesn’t result in failed traps, as the model codes in the US still suggest.

I look pretty intense in this screencap but feel like I did OK on the podcast. Thanks to Marty, Bre, and Ed for the invitation! www.youtube.com/watch?v=qbBH...

In Denmark, all sanitary drainage stacks are single stacks. In fact, there is no Danish technical term to differentiate the single stack from stacks with individually vented fixtures because it’s been standard practice for over 100 years. It’s just called a “stack” (stående ledninger).
