Why Campello needs this specifically
Extracting black water from a Campello triple-decker means working within tight shared-wall floor plans and containing spread between units sharing the same building.
Shared sewer laterals in older triple-decker buildings mean a single backup or root intrusion event can flood more than one unit at once, and cross-contamination risk between units is real once black water is standing.
What to know before you call
