More on sewers and pipe backups.
Seed Magazine led me to this, with a picture of a 'sewer cleansing sphere' obtained from Sewer History.
The sewers are regularly cleaned using large wooden spheres just smaller than the system’s tubular tunnels. The buildup of water pressure behind the balls forces them through the tunnel network until they emerge somewhere downstream pushing a mass of filthy sludge.
How big a ball would you use to cleanse out old & rotten attributes clogging up the corners & joints of your identity pipes? Where might you retrieve the ball afterwards?
And on the topic of pipe scouring, just because it's user-centric doesn't make it right.
