Start with your water meter. Go find it—usually a little dial in your basement, garage, or a box outside. Write down the numbers, then turn off every faucet and appliance that uses water.
Wait two hours without using any water (yes, even the toilet). Check the meter again. If the numbers changed, you’ve got a leak, my friend. Congratulations—you’re now a detective on the case!
Pro tip: Do this right before bed. By morning, your meter will spill the beans.
If the meter is digital, look for a tiny spinning wheel. A spinning wheel means water is moving somewhere it shouldn’t. It’s like your house is whispering, “Help me!” And you’re about to be the hero.
