All vertical soil waste pipes and traps must, if practicable, be exposed to view for ready inspection at all times and for convenience in repairing. Drips or overflow pipes from all other fixtures or from tanks shall run to some place in open sight and in no case shall such pipes be connected directly with a drain, waste or soil pipe.
Waste pipes from refrigerators or other receptacles in which provisions are stored shall not be connected with a drain, soil or other waste pipe, unless such waste pipes are provided with traps suitably ventilated. In every case there shall be an open tray between the trap and the refrigerator.
