Toilets are the most common sources of leaks in the home, wasting up to 200 gallons per day. Sometimes a leak is obvious – you can hear the water “running”, but more often than not, leaks are silent.
All toilets should be tested for leaks on a regular basis. Even toilets that are a few years old. The reason? Mineral deposits and worn toilet flappers. Flappers are an inexpensive, easy-to-replace rubber part that can be found at most hardware stores.
To see if your toilet flapper is leaking:
- Place a drop of food coloring in the toilet tank
- Wait about 5 minutes WITHOUT flushing.
- If any color shows up in the bowl without flushing, you have a leak.
Video below shows how to replace a worn toilet flapper. Be sure to get a flapper designed for your toilet make and model.
