The best way to check is to drop a leak detection tablet or food coloring to a tankful of clear water and wait to see if it shows up in the bowl. If the toilet is leaking, color will appear in the toilet bowl within 30 minutes. If coloring shows up in the bowl, you probably have a leak at the plunger ball. This may be evidence that the ball needs to be replaced or because the mechanism is out of alignment. Check the toilet for worn out, corroded or bent parts.
Most replacement parts are inexpensive, readily available and easily installed.
Flush as soon as test is done, since food coloring may stain the tank. The City of St. Petersburg is offering a free water conservation kit containing aleak detection tablets.

Traditional toilet use approximately five gallons per flush while the new ULV toilets use a mere 1.6 gallons of water per flush.
