Selected regulations
The pipes should be made of plastic or steel covered with zinc plating when the diameter is less or equal to 150 mm. when the diameter of pipes exceeds 150 mm, the material could be iron. If the pipes are constructed under the ground and the diameter exceed or equal to 75 mm, the material should be iron.
When the water passing through pipes is erosion, anticorrosion coatings should be covered inside the pipes or anticorrosion materials should be used.
When the diameter of pipes is less or equal to 50 mm, stop valves are recommended to be used. Gate valves should be used for the pipes which is larger than 50 mm.
