You know those lovely melon-scented flushable wipes designed for the newly potty-trained? Turns out they're not so flushable after all. At least not if you've got an aging sewer line full of Kadoo wipe-trapping tree roots.
$1000 later our line is as clean and free-flowing as can be (we got to view the proof via a live sewercam). And I have resolved that Kandoo wipes are joining Tampax ("white mice" in plumber parlance) as officially banned from the can.
