   What popa said. The fill valve does two things: It fills the tank, but it also has a small bypass that directs a bit of water into the bowl. This ensures that the bowl has sufficient water in it to manage the next "load".

   As to where the "excess" water goes: It's impossible to overfill a toilet bowl, as long as the drain is not clogged. Any excess water simply climbs over the trap that is part of the toilet and falls down the drain.

   Have a look at the pic....

   The water that is excess to that required to fill the bowl goes on down the drain line, once the trap is filled. A lot of the low flow toilets don't actually release enough water to fill the bowl to the weir height.

   Thanks for the reply. It appears that after the bowl/trap is filled and the tank has not, water continues into the bowl and into the DWV pipe.

   Thanks again,
