Oddly enough, Québec is one of the only places in the US and Canada that actually allows S-traps (unvented P-trap shown below though). This is in the Québec Construction Code but not in the National Plumbing Code of Canada.
Suds can be an issue in Asia where this setup is typical, except the discharge from the WM is vertical into the trap tailpiece of the floor drain trap rather than perpendicular. This is why washing machines often sit on a tray, allowing water or soap suds to drain back into the floor drain.
I’m a simple man but I am going to need to have this bathtub at some point.
Overflow drains are an almost non-existent feature on kitchen sinks in the US and Canada. It’s not illegal and some mfgrs allow it by special request. Kitchen sinks are a common source of water damage, which is why overflow drains are common in places more accustomed to building multifamily housing.
Take the False Creek Ferry from Sunset Beach Park after wandering around the West End to Kitsilano Beach Park (good views of Sen̓áḵw on this 5 min ferry), stop at one of the restaurants along 4th Ave, and head over from there to the Museum of Anthropology at UBC.
POV: The hydration quest is continuous and you now have an empty bottle of limeaid to toss. You’re in luck because you are never too far from a glass bin.
POV: It’s 30°C/63%RH outside, you’re staying hydrated and tossing your water bottle in the correct bin.
Somewhat related side note, this is the single best restaurant in London.👇
As Pride Month draws to a close, I would like to remind everyone to keep their Pride Pumps for their domestic hot water circulation systems running. 🏳️🌈🏳️⚧️
Here’s a recent short flight I was on, which is one of the better ones I’ve seen (Airbus A319). It even dropped below 1000 ppm for a moment in the air! High was at 2100. Average was around 1500 ppm.
Luckily these are dual aspect units but the bedrooms face the train tracks, limiting opportunities for cross-ventilation or using a mobile AC unit (as shown above) due to the noise. Not sure if those are fire doors in the unit corridor, but that could be another barrier to cross-ventilation.
New construction in London yet no air conditioning or solar protection. The UK housing stock is nowhere close to ready for the current climate.
@michaelburchert.bsky.social how does hemp insulation compare to straw and what are the advantages/disadvantages of the materials?
This was a really cool and unexpected surprise to close out the conference with!
Still better than a car with there other people in it though (I'm assuming the AC was on without the ventilation to get levels this high).
CO2 levels are consistently much better in the London underground than LNER/Avanti trains. This seems to be a consistent issue with HSR trains. Fuxing trains are the best that I’ve observed so far but still not great).
Nice cutaway of the drainage piping behind a standard European wall mounted WC.
Zero water seal in this trap. I remain unconvinced that this can provide a tight seal closure in actual working conditions but it’s interesting to see nonetheless. This is a popular product in Europe.
