This toilet has been dry and out of use for several months and is about two years old. After reconnecting it with a new seal and the cold water line tight with no leaks, it leaks like a gushing river whenever flushed.
It's fine sitting with a tank full of water - no leaks at all. But the minute the toilet is flushed, what a mess of water on the floor.
Which seal/gasket do I need to replace?
