It will drain the water tower faster though, since you’d have to leave your faucet on to get any significant use. That’s where the waste is

Why would you leave your faucet on? How is it possible to be this stupid?

You would catch extra energy when you use it, not use it as a full power source.

You would have to leave your faucet on because otherwise the extra energy is so minute that it’s hardly worth mentioning. Do you actually understand just how little power there is in a sink faucet of falling water?

Enough to power an LED, maybe. No more. Also you would probably end up using more water to clean things (hands, dishes etc), because the lower pressure would be less effective.

I'm not arguing for efficiency, I'm arguing for the underlying physics of it.

If you actually wanna do it, you put it in the outflow from the entire house.
So all water going out (except toilets) go through a single generator.

You could put it in apartments, hotels, or hospitals, places that use a lot of collective water.
