We have a pretty new toilet--it's a Toto one-piece. When you sit on it, you can hear a dripping, about 1 drip per second. This dripping begins when you sit down and continues for a while, but not forever: it doesn't drip all night.
If, while it's dripping, you open the tank, you can push on the flap and stress other inside-the-tank components without causing any change in the dripping.
If you turn off the water to the toilet, the tank doesn't empty. While it's dripping, there's no visible turbulence in the tank or the bowl.
My theory is that sitting down compresses the seal or otherwise disturbs the toilet and the water is somehow dripping down the drain (water from the bowl flowing over the P-trap?)
But I can't figure out why it drips for so long (at least a few minutes) and so regularly. Is it possible that the seal compresses and it takes a while to return to its shape?
Thanks for your ideas or opinions.
