First up: look for the loud leaks. You know, the ones that announce themselves like a bad karaoke singer. Check under sinks for puddles, drips, or a suspiciously cheerful drip-drip-drip rhythm.
Don’t ignore your toilet. A running toilet can waste hundreds of gallons a day, and it makes a sound like a bored ghost. Listen for a faint hissing or a constant trickle behind the bowl.
If you see paint bubbling on a wall or ceiling, that’s not artistic expression. That’s water trying to escape its pipes and redecorating your home without permission.
