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.
USA checking in with one almost exactly like the picture
Its on the southern hemisphere.
IDK which way threads go on your country, but in the US at least you turn counterclockwise to loosen something.
Looked over their entire catalogue and couldn’t find it, probably isn’t in production any longer. I’m almost certain though that the color is called “Vibrant brushed nickel” and that it’s fucking expensive
I picked it from Google images, they go through product lines like Kleenex.
That’s a German brand of faucet.
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!!
Observe while I shower comfortably with:
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.
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.
Same man, it’s been a dream since installing this.
These things existe for at least 30 years, I don’t understand why anyone would want to use anything else for a shower or bathtub.
Do they hold for 30 years?
Definitely not :) I had to get it replaced at my flat this year. There is a filter inside that can get block if you have hard water or debris.
Ah, see, we have high calcium here, didn’t even know this thing exists.
Don’t let that stop you getting the ultimate shower experience! My parents also have water with very high calcium at their house and I don’t think they had any problems with the faucet in the past 15 years.
I live in a rented place, they were doing repairs to the heating systems, several times we had brown water coming out the tap. I bet they installed the cheapest option, plus the debris in the water, this fucked it.
Just invest in a good thermostatic faucet and never look back !
What is this?
Thermostatic faucet
They’re so sensitive because the person who installed them didn’t care enough to adjust the regulator. If this bothers you, you can take the handle off yourself with an allen wrench and adjust the valve so that when you turn it on, it’s the perfect temperature for you every time.
This is a great idea if you are the only one using your shower. If you have 4 family members, each of whom likes a different shower temperature, it is less ideal. I think controls that allow separate on/off and hot/cold dimensions are best for most scenarios.
Yes, but this wastes water, so if you’re trying to be green, you should be able to open up the valve to full hot.
Not only does it waste water, your shower will take longer to heat up.
Also, depending on where you live the perfect temperature changes a lot because of outside temperatures. If you use all the room temperature water in your cold lines then start pulling cold water from the outside. You’re going to have to adjust it. Bigger the house, the more the problem.
But if you have to dump out your entire hot and cold lines to even begin to step in the shower, that’s a ton of wasted water.
Answer is a thermostatic valve. It will just use hot water until it needs to mix in cold. If your cold water temperature changes, it will adjust it automatically. You really do pick a temperature to set the valve at, and then the handle just controls the flow rate.
The regular for a standard mixing valve is there only so you can’t turn the valve to burn you. When people keep their water tanks at 160°F, a full turn to the left would be devastating if you’re standing in it.
That’s 70ºC, 49ºC (120ºF) is usually plenty hot enough and the recommended temperature. It can actually cause burns with long enough direct exposure at 50, 70 is madness.
In the US the standard safety temperature for the water heater is 120° F
You don’t need it higher than that unless you have a small tank and use a lot of it. Tankless is 120°F.
I don’t know where you got 70°C from.
You said:
When people keep their water tanks at 160°F
That’s 70ºC and I’m agreeing that it is a ridiculously high temperature to keep a water tank at. That’s instant second degree burn temperatures, completely unsafe.
Ohh I see now.
Yeah 160° is too hot. But people do it. Small tank multiple showers needed. You can stretch it.
I was saying for people that have their water too hot. The regulator inside the US mixing valve has a stopper so you can’t go to max hot. That’s all the piece inside does, stops you from turning the valve more. Doesn’t help reglate the temperature. Someone in comments said their regulator is bad and I thought it was OP.
I keep mine at 145, because I fear legionella.
I tried that and it still ends up either freezing or burning, unless I turn the handle all the way on, then half way, then creep it up.
Is that what a bad mixing valve looks like?
If you live in the US, then you probably have a standard mixing valve
If you live elsewhere, it’s probably a thermostatic one
For US:
You want to turn your handle all the way hot to clear your hot water lines fast, it’s room temperature in the hot water lines. Once the water is hot, then you start mixing in cold water.
The first cold water is from the lines in your house. It is heated or cooled by your home, basically room temperature water.
So say I turn the valve on full hot. Pure hot water is pouring out. Now you add some of that “room temperature cold water” to get to your perfect temperature.
Now, once you run out of “room temperature cold water,” it will start pulling water from the street.
I’m guessing you live in a cooler climate area?
120°F + 70°F = perfect temperature
But if the outside water becomes, say 50°F after you use all your water stored in your cold water lines
120°F + 50°F = colder water
So you have to add less 50°F water, which means slowly creeping your valve up until you have steady temperature water going to the valve.
Things like the type of water heater matters. If you use a tank then as you use water it adds water. If you keep your tank at 120° and you’re adding 70° cold water or 50° water to the tank matters. You also have “room temperature water” in your cold lines going to your tank at first, then colder water. So that creates another “lag” in temperature
US standard mixing valves aren’t as nice as a thermostatic valve. They are just cheap and standard and work well enough in most places.
Thermostatic valves allow you to select, say 100°F water, and the knob just controls the water flow rate. No matter what, the water that comes out of your shower will be 100°F. As the water coming into your house gets colder it will automatically adjust. As the water from your tank gets colder, it will automatically adjust.
Sounds like your valve is working as intended though
That’s fantastic info. Thank you! Though it sounds like I want to upgrade to thermostatic.
It’s definitely a nice upgrade. Little pricey in the states because hardly anyone uses them, so they are “specially”. Not any more difficult to install really but plumber might charge a premium.
Yeah, you need a new cartridge for yours.
Well, if you turn it all the way on, it should have the same temp as if you did it the way you described, so yeah, the regulator might be broken. A valve should last you several years before it starts leaking or breaks, so if you’ve had yours that long, it might be time for a new one.
The good news is that replacements are pretty cheap, and for this style of faucet they’re pretty easy to install, usually requiring only a screw driver and probably a pipe wrench to loosen the retaining ring. And if you have a name brand like Delta or Moen, it’s covered under a lifetime warranty as well.
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
Weird.
I saw “melts tungsten” and my brain decided this was in German.
Same lmfao
I think it’s so late here that I assume Lemmy is sprechening Deutsch by default
Speaking as a Dane, I too had to recalibrate from “heavyrock” to “tungsten the element” 😁
Your water heater is set too hot or you don’t have a mixing valve after your water heater
You don’t need to adjust your water heater or add a mixing valve. You just need to take off the handle and set the temperature regulator on the faucet itself.
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.
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.
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.
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.
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.
Turn down the temperature of your water heater.
Lower flow temperature makes it easier to adjust.
Because it is hard to make a cheap valve that has a wide mixing ‘sweet spot’.
Rich people showers don’t have this problem
