(2) The internal diameter of every soil pipe from a urinal or bidet shall be not less than the internal diameter of the outlet pipe of the trap of any fitment to which the soil pipe is connected. (3) Every soil pipe shall be properly connected to a covered drain without the intervention of any trap. Cap 123I reg 27 Waste pipes (1) Waste pipes to which the waste from one waste fitment is discharge shall have an internal diameter of not less than- (a) 32 mm; or (L.N. 294 of 1976) (b) the internal diameter of the outlet of the trap to which the waste pipe is connected,whichever is the greater.

Cap 123I reg 29 Access to soil and waste pipes (1) Sufficient access shall be provided, by means of cleaning eyes or other approved method, to enable soil pipes and waste pipes to be cleared of any obstruction.
