Kwun Tong-specific knowledge. Kwun Tong industrial-converted-residential buildings have unusual drain configurations — original commercial-spec pipes never designed for residential volume. We see weekly calls for blocks in converted 1970s industrial-now-residential buildings around Hung To Road / How Ming Street.
