you need a new flapper valve. it leaks slowly until it is low enough to make the float open the water valve. then water flows in again until the level raises the float and turns it off again. really a simple fix. even a novice can fix it. just take the old flapper valve to the home improvement store to be sure you get the right one.

You are losing water one through your tank. Here's how to test. Put food coloring in the tank. When you hear the toilet run, go up and look in the bowl. The bowl water will be the same color as what you put in the tank. Get a replacement flapper and follow directions carefully. Not hard to do, you just need to make sure the inside of the tank is dry. Other possible places you are losing water is through the tank bolts or the tank supply tube...either one with show wet spots on the floor/bowl the same color as the ink you put in the bowl. Tank bolt replacement is simple, just take out the old ones (and washers) bring the down to your nearest hardware store for matching, (you should know the name of your toilet to get the right flapper, or just bring the whole thing with you, even if it's connected to the overflow tube. Supply tube also easy to replace, just tell your hardware guy you need a tank fill valve, like a fluid master, easy to install very few tools, Just make sure you shut off your water before disconnecting anything and don't overtighten anything. You can always tighten it more if it leaks, but if you overtighten and break it, now you've got a problem.
