Rant: I thought those new 'smart' flush valves were just a gimmick until I saw the water bill at a 40-unit office building drop 22%.

That 22% drop is huge for a building that size. Was it just the toilets, or did they swap out faucets and urinals too? I'm trying to picture the full setup they used, because retrofitting 40 units can't have been cheap. The payback period on that investment must be the real story.

But who even checks their water bill that close?

park.adam mentioned who even checks their water bill that close, and honestly I read this article about a school district in Texas that did the same thing. They swapped out all their old toilets for these sensor flush valves and tracked it for a full year. The savings were even higher on the urinals because of how often guys flush them for no reason. It adds up fast when you have a building that size and people are just walking away without flushing half the time.
