All conduits, pipes, cables or others dedicated in particular to the conveyance of fluids (e.g. drinking water, rainwater or sewage), energy (e.g. electricity or gas) and data transmission (e.g. telephone communications, internet, etc.). In divided co-ownership, the piping and wiring is presumed to be a common portion. It is therefore the responsibility of the syndicate of co-owners to ensure its maintenance and preservation. However, the part of the piping and wiring, which is used only as a private portion, is not part of the common equipment and is therefore not governed by the presumption of article 1044 of the Civil Code of Quebec. This part would then be a private portion according to the definition given by article 1042 of the Civil Code of Quebec.
