4. All new services or alterations or repairs to existing services are to be carried out to the satis- faction of the Water Authority. Pipes and fittings of approved quality only are to be used. Samples may be seen at the Office of the Water Authority.
5. No pipes, valves, or other fittings forming part of a service must be covered up until they have been inspected and tested by the Water Authority. As soon as a service has been inspected and approved, it will be connected to the waterworks, and the supply will commence. The connection will be made by the Water Authority's servants only.
6. Whenever the owner or occupier of any tenement wishes that a service should be made, altered, extended or repaired at his cost by the Water Authority, he must make application by filling in a printed form, obtainable on application at the Office of the Water Authority.
On receipt of this form, duly filled in and signed, the Water Authority will cause the premises to be inspected and will arrange with the owner or occupier as to the manner of construction of the pro- posed service.
7. The applicant for a service having signified to the Water Authority his acquiescence to the final arrangement, proposed by the Water Authority, the service will be constructed accordingly.
8. The Water Authority does not undertake to restore any crnamental floors, wall-surfaces or other decorations, which may be disturbed by the work.

10. The cost of services laid, altered, or repaired by the Water Authority shall be paid to the Trea- sury in cash in full within fourteen days of the presentation of the account.
11. The Water Authority will not be responsible for the maintenance or repair of any service constructed by the same, after the date of the account for construction.
12. The Water Authority, notwithstanding that its requirements have been complied with as regards services, does not hold itself liable for any damage that may arise in premises by bursting or overflowing. Nor will the Water Authority by any permission or act extend its responsibility beyond the main-pipes in the public thoroughfares.
13. All pipes, used in the construction of services, are to be of cast-iron of approved thickness and quality or wrought-iron both to be coated with bitumenous composition; or galvanized wrought- iron piping (the latter however is not recommended).

15. Cast-iron pipes are to be substantially jointed with lead and yarn. Wrought-iron pipes are to have screwed joints and sockets.
16. Lead pipes will only be permitted in new services when the water which passes through them cannot be used for drinking or cooking (down-pipes to water closets or overflow pipes from cisterns, for example). Provided always that owners of premises which are now provided with lead- services will not be compelled to remove them unless in the opinion of the Water Authority they are too weak, or otherwise defective.
17. Every service is to be provided with a strong gland stop-cock with solid bottom, either of brass or of cast-iron, if of cast-iron, the plug to be asbestos-packed, or, with a screw-down stop-cock with a loose-valve; or, in the case of services larger than 2′′ in internal diameter; with a sluice or slide-valve.
The stop-cock or valve is to be fixed under the pavement where there is one, and as near to the tenement as practicable, and it is to be provided with a cast-iron cover and lid so that it may at all times be accessible; or, the stop-cock may be fixed above ground in the tenement immediately inside the door in some readily accessible place.
18. All draw-off taps are to be of the pattern known as "screw-down" with loose valves, not liable to turn on their seat when screwing down. Patterns of the taps may be seen at the Office of the Water Authority.
19. Every cistern, to which water is supplied from the waterworks, is to be provided with an Equilibrium" ball-valve of approved pattern, and the ball-valve is to be so adjusted as to close the supply when the water-level in the cistern is two inches below the edge or overflow if there be one.
20. The overflow pipes of all cisterns are to be brought out to the outside of the building and must terminate in some conspicuous position, so that any leakage may be easily detected. No over- flow pipe from any cistern must on any account be connected to any drain or sewer or to the waste-
