It looks like incorporating a wider toilet pipe "system" (everything from the u-shaped tube of the bathroom toilet down to the home pipe that finally connects to the greater "public" sewer system) should make for an overall "less cloggable" toilet experience.
But, since homebuilders can't alter the general public sewer pipes dimensions, is there a legal limit as to how maximally wide the pipes of a home sewer system (just for the house itself!) can be? It seems like there would be some limit here to prevent the general/public sewer system itself from getting clogged -- by keeping everyone's "home" sewer plumbing widths to a minimum!
