Just a question out of curiosity....I see 3"/4" toilet flanges, where you can put the flange inside a 4" or outside a 3".

Does this affect the size of the water spot in a toilet? (smaller water spot if the 4" piping needs to be refilled instead of 3")

Does it also affect the flushing "power" (will inside a 4" give you more oomph)?

Thanks in advance.
