A couple months ago, I got a huge bill from the water company. Turns out that a toilet that we rarely use was leaking internally, running up the bill. It had been doing this for almost a full month.
So I made myself a reminder to check the little spinning indicator on the water meter once a week to make sure it wasn’t moving when it shouldn’t be. Problem is, the meter is kind of hard to get to, in a dark area behind a panel.
Solution: stick a Wyze Cam in there. Now I can check it easily anytime I want.
Same problem for 3 months till I found the toilet and my kid not paying attention. Put a sensor on toilet, catch next time someone flushes that it doesn’t code. Get creative tie it close to ball when it reaches the top it’s off.
