theory: f(x) = x

practice: f(x) = -8 + 16/(1+e^-10x)

Maybe it’s just mine but can we agree that a lot of showers do that?

      I have this issue in a home built just barely pre-lockdown. So the issue isn’t wear and tear.

      What should I be looking for to fix this?

        Sometimes even new(er) valves fail. If you have hard water then that is plenty of time to mess one up. In a best case scenario, you can lookup your make/model of faucet to buy a ‘cartridge’ for it and find the instructions on how to replace that. In more extreme cases / poor designs, you could have to tear into the wall and replace the entire thing.

          You might also see if you can find a plumbing community and post as many details as you can… I’m an experienced DIY person who has done a lot hands on and read a lot, but I’m not a plumber so I still have blind-spots.

    I used to live in Japan and I had an in-line gas water heater. Outside the bathroom and kitchen was a thermostat for the hot water. I just set the temp for a good shower and blasted the hot water. It was bliss. America really needs to catch up with Japan in bathroom tech in general.

      Hey now I have a new two tap shower… And still don’t have this problem. I think that’s just the solution, 2 taps are better than one.

    You can plot my shower in three dimensions with water pressure.
    The hotter the water, the weaker the pressure.

    I drop the pressure, the water gets hotter :)

      Oh god, same.

      I have nearly figured out how to increase the pressure without changing the temperature.

      I still boil/freeze myself sometimes though.

        You could try restricting the shower head to a smaller output area. This way you would have a higher water flow

          Ah, I meant increasing the pressure when I notice it’s a bit too low for my liking.

          My shower lever has to be pulled in a specific diagonal direction to increase pressure without causing the temperature to change drastically.

    f(x)=x? In theory the water in a shower can get infinitely cold? That would be some shower that can go past absolute zero. It would be interesting to shower in a Bose-Einstein condensate.

    If i remember correctly thats also close to hyperbolic tangent

    Thats what i used in simulating very fast semiconductor switches so it wouldn’t cause solver issues. Might be better ways tho

    Your pain receptors fire at some fixed threshold so anything beyond that very suddenly gets uncomfortable.
