Is your water bill mysteriously high? You've installed a low flow showerhead, and you monitor the amount of rain your lawn receives in order to cut back on lawn water. And your water bills are still high? That's mighty suspicious. A leaky toilet is the most common source of high water bills, and they are so easy to fix. But before you go fixing the flapper, you should test your toilet first.

Here in California, we are serious about water conservation. We've outlawed cleaning sidewalks with water, and the Drought Busters are working to prohibit other water wasters. That's some serious water conservation. So check your toilet and conserve water before the Drought Busters start throwing around their fascist water rules in your neck of the woods. ;)

Here's how to do a dye test.

1. Clean your toilet. Prepare your toilet for what lies ahead. We don't want any murky readings.

2. Purchase food coloring or dye tabs found at hardware store specifically for this purpose. (Do not use any other types of dye. Stick with the water-friendly stuff.)

3. Put the dying agent into toilet tank.

4. Wait 15 minutes. Make sure nobody else tries to use the toilet in that time.

5. If the dye is in your toilet, you have a leak. If the dye is not in your toilet, then you can have a party.

The most common problem is a leaky toilet flapper. Check out this troubleshooting guide for more fixes.
