What home solutions actually work when problems pop up suddenly?

Instant home solutions have been on my mind lately after a small leak turned into a long evening of trial and error. I kept searching for quick fixes, but every advice felt different from real life. I’m curious how others handle these moments. Do you rely on DIY tricks, neighbors’ tips, or online guides? In the middle of the chaos, instant home solutions sound helpful, but which home solutions have truly worked for you?
