Rainwater toilets and greywater showers: City tries new water-saving tricks

- Totally agree, those sensors can be a pain—I've had more than one tenant call me about "broken" water level alarms that were just confused by condensation or the tank walls.
- Analog float gauges are old-school but they just work. Less to fiddle with, less to break.
- One thing I’ve learned: always keep a manual shutoff valve handy. When the tech acts up, you’ll be glad for it.
- Not against new gadgets, but if it needs a software update to flush, I’m out. Sometimes simpler is better... especially when you’re the one getting the midnight calls.
