What kind of fucked shower knob turns counterclockwise
Australian, just like their toilets spinning water the other way.
If I remember correctly Mythbusters disproved that. It depends entirely on the way you pull the plug.
So australian toilets have defective plugs, got it!
Well, essentially, it’s that the coriolis effect, while a real thing, is much weaker than most other factors in play. If everything else is neutralised or near to it, the coriolis would indeed be the remaining decider, but that’s very unlikely in practice.
The coriolis effect has nothing to do with this. The coriolis ‘force’ is not a real force, it’s just the product of things trying to move in a straight line on a rotating surface which to observers on that surface looks like a curve which implies a accelerating force. Usually this applies to things flying through the air, because the are moving independent from the ground. Something that is not a force can not influence something like the water in a thub.
What people confuse the coriolis force with is the centrifugal force of the earth’s rotation. But this force increases radialy but is tangetialy evenly distributed, which means it’s symmetrical so it doesn’t matter which hemisphere you’re in. It doesn’t point ‘left’ or ‘right’ it only points ‘out’ or ‘up’. Unless you’re right on one of earths rotational axis none of those effects matter.Otherwise people on the equator, their toilet water wouldn’t spin at all? It would just go straight down, no spin.
Water swirls because it’s the course of ‘least action’ for the draining process. It creates a laminar and continuous volume exchange through a hole. Pipes are usually filled with air which has to be exchanged with water to drain. Physics just optimizes itself to be as efficent as possible with this. You can’t have a perfect draining surface so so currents in one direction will always be a little bit stronger that in the others. Gravity applies a constant acceleration, so this small difference in initial direction will be amplified over time creating a swirl.
In case of a toilet though, the water is already introduced in a swirl during flushing. So none of the above even matters.
USA checking in with one almost exactly like the picture
Yeah I’ve seen plenty like this in the US.
Lefty loosey, righty tighty
You know lefthand threading is a thing, right?
The ones at my gym.
In seriousness, it’s often about water pressure and how your hot water is fed. If you have very high water pressure normally but a solar hot water system where gravity and input pressure play a role, you’ll naturally have an imbalance on hot and cold. When you turn the handle on the shower you’re lining up two holes in the shower cartridge (in the handle) with the two hot and cold water pipes, the resulting mix comes out a third hole which feeds the shower head. As you turn the handle, one hole opening gets smaller and the other bigger- thereby changing the ratio of hot : cold. When you already have a huge pressure of cold water pumping in, the degree of rotation needed to go from warm/almost just right to PURE HOT WATER is minuscule. Usually the cold will stay pretty cold for about half of the handle range of motion too.
If water input pressure being high is a problem you can put a reducing valve on your system overall or you can buy Venturi style pumps which add pressure into your hot water system.
You’ll normally find when it’s pressure imbalance that it’s easier to balance the temp when the tap isn’t open full bore. But who wants a weak-ass shower stream!!
This, exactly. When we redid our bathroom, we went from “immersion tank” hot water with about three metres of pressure behind it, to central heating in a closed system, where both hot and cold have the exact same pressure, about thirty metres head. Went from being basically impossible to have a shower, to being an absolute pleasure where nearly the entire range of the tap gives a useful temperature, and it’s got a right blast of pressure behind it too.
Another alternative would be an electric shower - since you’re just heating up cold water, the pressure is “always the same”. They tend to be a bit pathetic and crap, tho.
Observe while I shower comfortably with:
When I first moved to Japan over twenty years ago they were already about a hundred years ahead of typical US toilet/bath technology. For me, using one of these faucets where you can just set the temperature by number was like Liko getting beamed from her hut directly onto the damn Enterprise.
Interesting, so it adjusts the flow of hot/cold in the fly to keep a consistent temp? That’s amazing, thought I imagine it would have the same issue I have at the end of the shower where it’s on 100% hot just to eke out a bit more time
You can adjust the temp on your water heater to solve that.
Growing up in rural France, we had these at home for as far as I can remember. They may not have been the norm 30 years ago, but at least common.
What’s that called?
Thermostatic (shower) tap. They are pretty common where I live in Europe. They actively adjust the water mix to stabilize output temperature. Also great for when somebody flushes the toilet or turns on a tap elsewhere in the house while you’re showering.
seems like a smarter solution than what one house I lived in did of just oversizing all the plumbing and having a recirculating hot water pump (probably could help prevent freezing, but it only got to -40 once or twice there) so you could run all faucets, the washer, and the dishwasher and still have pressure at the furthest shower.
You notice the difference in flow, to be sure, so oversized piping may still be a good idea. But the temperature shift will be soft and correct itself promptly.
I really don’t understand how this is still not the standard everywhere… The cheapest ones aren’t even that expensive and already way better than the alternative… Don’t think I’ve not showered with one of these in the last 25 years, except for in some kind of social housing projects homes.
Yes, but that is not a fair comparison, these are European.
This technology is only possible with degree Celsius. It is impossible to adapt to degree Fahrenheit.
You might have a point there
Except British homes which have two separate showerheads, one fully hot and the other fully cold.
The trick is to spin.
British when straight into inventing the radar and completely skipped over the invention of warm water.
Ah wel… the British have always been a bit particular to be honest.
What is this?
Thermostatic faucet
Okay I’m gonna be real. I didn’t understand the meme at first and thought you were showing a melted door handle and the guy in the meme was trying to melt another door handle with his mind
I was fully prepared to read a bunch of comments about how are door handles so sensitive to heat due to their metallic composition and how you absolutely cannot melt things with your mind that the actual comments tripped me
Warm 👏 thoughts 👏 can’t 👏 melt 👏 steel 👏 knobs 👏

See this is what I was expecting thanks
You need at least the heat of your hand to melt metals. Or at least at least the heat of a cold but not cold wave winter day.
Weird.
I saw “melts tungsten” and my brain decided this was in German.
Fun fact: the german word for tungsten is Wolfram
Wolfram alpha suddenly makes even less sense
Same lmfao
I think it’s so late here that I assume Lemmy is sprechening Deutsch by default
Set your water heater lower. Like: make sure it’s above 120 at all times (130+ preferably) to prevent legionnaire’s, but 140 is PLENTY for most home uses. And it means you get a bigger range to move your mixer taps to.
That’s Fahrenheit right? Or are you suggesting 100+ Celsius?
Your water heaters don’t have a “Steam Blast” setting? How do your bidets even work? Do they just dribble cool water on your anus? How weird.
It’s Kelvin
This is the only correct answer. I never said “degrees” anywhere, so it’s obviously Kelvin!
Celsius of course. Only babies shower in 140 Fahrenheit!
Last i checked, that would no longer make it hot water, but I use the dumb numbers where 212 is boiling
Actually at household water pressures, water’s boiling point is somewhere from 140-160°C, so it’s actually somewhat plausible. I’m sure some less heat tolerant stuff would have to be upgraded, but the system’s total pressure would be about the same (with the added danger that the consequence of a pressure failure would be a steam explosion instead of a leak).
And of course turning your faucet on hot would now blast out a stream of boiling water propelled by superheated steam, which is probably less than ideal.
Came to say the same thing. Not sure why people want boiling water on tap. If I need to boil water I use my kettle, and save money by not heating a tank of water to near boil all day.
Your water heater is set too hot or you don’t have a mixing valve after your water heater
i adjusted my heaters max temp to what i like and just turn shower/faucet to the hottest setting in winter or lower in the summer.
My heater only heats while water is flowing through. Otherwise it cools down.
This may have consequences not killing things that like thriving in warm water.
Could be an issue in some cases, but mine only heats while water is flowing through. Otherwise it cools down. Also the input water in my region is clean and drinkable, so it hasn’t enough food for germs.
Inline heating is pretty safe to do that, aye. I’d worry about listeria in a tepid storage tank.
Legionella won’t make you sick if you drink it, only if you breathe it in. It exists in clean drinkable water all over the world. It’s capable of hibernation and able to survive without nutrients for long periods. So it’s at least a potential risk any time you breathe aerosolized particles from water that is not hot enough to kill it. Any type of water heater that heats to 60 degrees Celsius will kill it.
The cartridge is likely bad. They get clogged up with lime scale over time and start to perform worse and worse. Either replace the cartridge or the whole faucet itself.
Because it is hard to make a cheap valve that has a wide mixing ‘sweet spot’.
Rich people showers don’t have this problem
You should just move to a more tropical area. Where I live, I only ever use the “Cold” tap and sometimes, even that is too warm.
That’s how it is for me in the summer, and Jersey ain’t exactly tropical. But it’s kinda nice being able to just turn on the shower and get in. The cold water is likecold in the summers, and it’s usually humid, so a shower with no hot water ends up very refreshing.
So there are lots of good answers, but there’s one I haven’t seen: The type of shower control in the photo is probably low quality, cheap, meaning the internal parts do a poor job of mixing the hot/cold water.
Adjusting the water heater may help, but you might also consider upgrading the shower faucet.
Probably American build.
Yep, if China had products at this quality and price point muricans would never shut up.
Nah, Brougham.
All the way to the left, then back off 1/16".
Burn me, baby.
Come to Japan (and, so I’ve heard, several European countries) where we have a temperature setting on the tap. Mine caps at 40 by default, but you can press a little button and make it hotter if desired (up to however hot your water heater puts out).
Turn down the temperature of your water heater.
But that reduces the maximum length of your shower.
And saves both energy and water.
Boo, but I’m aiming to bring about global desertification any %
