I... Genuinely only realizing this now
(lemmy.world)
For real. Everytime I get in the shower I end up having to point the showerhead away and cower from the cold water and I could have just turned it on first?
I stand in the shower and turn it on hoping it was indeed left with the shower head disabled, then I turn it on low pressure and let water flow until its warm.
No need to waste arbitrary amounts of water! If you don't have a normal shower (you're american) and only have some on/off shower pressure control, step inside, run the tub until it's warm, and act like a human being who can take the .3 seconds of cold water that may still be in the pipes between the diverter and spout. Odds are the cold water was drawn down from the water rushing out of the spout anyway, unless you have an adjustable showerhead. See step one.
The amount of water is the same. It’s the volume held by the pipes between the water heater and your bathroom. that’s the same amount of water, whether it comes out of the bathtub or the showerhead, at a high or low rate of flow.
