    My first thought was to flush the toilet whenever you needed warmer water. I used to rent an apartment where I had to turn on cold water in the sink to get hot enough water in the shower.

      This doesn’t even make sense from a plumbing perspective

        that’s what I thought at first, but there is actually a way that it makes sense

        you have hot water and cold water with a certain amount of pressure behind them feeding your apmt. if you turn the shower to full hot, the valve is still going to mix it with cold water. however if you take the cold water out at the sink prior to the shower feed, it’s not going to be replaced by more cold water if the system doesn’t have enough supply to keep up with it. so your shower water is being mixed with less cold water than before, resulting in a hotter mixed stream from the shower head

        and like maybe there’s other things going on and it’s not the same in every situation and all that, but you can test this yourself and get this result, so…

          Do you not have a temperature dial on your shower that lets you control this directly? If I feel like I need to burn my skin off I can turn the temperature all the way up and have 100% hot water.

        I don’t know what world you are from but my showers have also gone hot when the toilet is flushed
