The only correct kind of faucet is the kind with a thermostatic handle for temperature, and a separate handle for flow.
They are almost exclusively available for showers and that’s stupid. It’s the correct solution for the problem, with extremely few drawbacks.
The only improvement I could see is making the temperature handle short circuit to the drain until the water going through is hot enough. But I dont know if that’s really possible without electronics, and I really dont want my faucet handles to be plugged in or take AA batteries.
Being able to maintain the ratio with fluctuating water pressure would be cool too. It’s probably possible to do entirely mechanically.
Something like this works. Just turn the water off with the spray nozzle, not the handle. https://share.google/1HpxlLwZ6RMXGdMoS
I used to have a kitchen sink faucet with the mixing handle on the side, that i installed after the 2 tap mixers.
So the 2 taps controlled hot and cold, which fed into the faucets cold line, and the hot line was capped off, making the handle only control flow, and temp was the 2 knobs. (I did this out of laziness because I didnt want to unsolder and resolder in new fittings)
I bet it would not be hard to 3d print a little ring with a twisty arrow that you could use to “save” your last handle placement, kinda a neat idea.
Have you tried using your own memory?
There are! They’re called thermostatic faucets.
I’m amazed at the comments explaining incoming water temperature fluctuations and pressures…
No no, thermostatic tap/faucet mixes waters depending on the output temperature. Ignores all of the variables except the thermal mass (I guess reaction speed) of the thermostatic system.
I think they are normally like 10x the price of a standard mixer tap tho.
So, it’s a budget choiceWhen I bought the faucet for my bathtub, the regular one was 35€ while the thermostatic one was 60€. I wonder why they still make the regular ones
Yeh, bath/shower ones seem affordable.
But for a standalone sink, they seem to be significantly more.
Yeah, and obviously if the ‘hot’ water isnt hot, there isn’t anything it can do.
I have a feeling like you could do a completely mechanical one. Like a way to push it open and a part gets pushed out to stay put so when you open the faucet back up it bumps it and has a little resistance when it first turns so you don’t accidentally move it. Rotate the full way around to reset.
My kitchen faucet does this. It’s a 2-axis lever. Y axis is the temperature adjustment, X axis is flow. As long as you leave it set to the same Y position when you turn it off and on, it’ll be at the “last used combination”.
Mine did this was well. If looks like a little stick on a ball
My super basic faucet handles are exactly that…you twist it left-right to set temp and tilt it up-down for pressure from off to full. We just leave it rotated wherever we like it for temp and tilt up to turn on each time to the desired pressure. Our water pressure is always variable, so the amount tilted up varies, but the “rotational temp” almost never needs changing. There’s no fancy thermostatic valve in these like some shower have. There’s even those fancy kitchen sink faucets that remember everything and you just tap them with your hand and they automatically turn on/off to your settings of temp and pressure. I think they are called “touchless faucets”. Pretty sure even Ikea sells one.
I feel like sink handles like mine are super common, too. I’ve had similar ones in the states and in Europe…
Keep in mind that mixing the levels of hot and cold water isn’t the only factor in the final temperature. It’s also the actual temperature of the water in the pipes. Depending on where your pipes run, the cold water in the pipes may be warmer or cooler than the underground source of the water. The hot water may also have cooled more or less since leaving your hot water heater. Initial temperature may therefore be too hot or cold compared to where it ends after a period of use.
Ambient temperature in the room will also affect how hot you want the final temperature to be
People here saying single handle faucets must have much better ones than what we’ve got where I’m from, no fucking chance of getting the same temperature again after shutting it. And the middle of it is extremely sensitive, it goes from 10% to 90% in like the middle two millimeters, and I think the pressure of the hot water overcomes the cold’s so you have to turn a bit left and then right again to stabilize the temp.
For my shower, which is the one that matters most for me, I got a thermostatic one—you set the temperature on the right handle and the flow on the left one, and that’s it, perfect temperature forever. Even if someone flushes, which only happens when my sister is visiting because she doesn’t understand boundaries, it doesn’t change one whole degree for more than a second, only the flow is be affected.
As a side note my grandma’s bath tube some 30+ years ago (it had probably another 30 or more) had two handles for hot-cold, left and right, and then another two for the shower-faucet flow, up and down. It wasn’t as fine tuned as my modern one, but worked quite well. You would only open or shut without touching the proportion of hot/cold.
everytime
Not a word, my dude.
Not needed because you shouldn’t be using warm water to wash your hands. Cold only.
Why?
What I read is that cold water cleans just as well as warm water but uses less energy, therefore better for the planet overall.
I agree it is more comfortable, but that was my reasoning.
