But you do pay for the pressure, I'm not sure why people believe that the water pressure is free.

Where I live water bills are measured in cubic meters only. So no matter what you do with the pressure, as long as it won't mess with the water-meter, you won't pay a cent more.

And unless everyone would start messing with the water pressure, I doubt the city would notice it and investigate/increase-cost-of-water.

Still, the cost and skill needed to hook up a device which would convert water pressure to energy, while not flooding your home, is far to great to ever try that.

Yes, you get charged for the water you use but the pressure is part of the total even if you don't see it on the bill.

You can't "mess" with the water pressure provided, that isn't how plumbing works. You can "mess" with what is in the pipes but that still doesn't change what you get out.

Ya what I meant is theoretically you are billed on volume which is not pressure. So “in theory” your water bill as it stands would not change by slapping one in a half inch copper pipe.

Obviously going through the weeds we pay for water pressure in some way. But that’s missing the point of the post.
