Find a leaky toilet with food coloring
A worn flapper can waste water silently all day. A few drops of food coloring show it in 10 minutes.
- Lift the tank lid and add a few drops of food coloring to the tank water.
- Don't flush. Wait 10 minutes.
- If color shows up in the bowl, the tank is leaking, usually through the flapper.
- Flush afterwards so the coloring doesn't stain.
Tip: Flappers are cheap and wear out. Replace one at least every five years, or as soon as the dye test shows a leak.
Try it now: Add the drops now and check the bowl after your next 10 minutes of scrolling.
