Why does my Collingwood warehouse conversion keep having drainage problems?
Usually because the building’s drainage was designed for its original industrial use and never fully reworked for residential or hospitality use. Trade waste lines, old pits, unusual falls and connections that make no sense for a kitchen or bathroom are all common. The symptoms recur because the underlying configuration has not changed. A CCTV inspection and drain map of the building is usually the single most useful thing an owner or owners corporation can commission — it turns a recurring mystery into a defined problem.
