Reservoir Main with the thicker Pipes supplied under Reg. 254, which were supplied for a much higher test pressure of 1,500 lbs., it is hardly likely that the result would be satisfactory.
24. I suggest, therefore, that the Colonial Authorities be invited to make enquiries as to whether any of the 5" Pipes supplied under Req. 8 were used for the Peak Service Reservoir Main, and whether 5" Pipes were purchased locally to make up the number required for the Main.
25. In this report I have not dealt at all with the question of water hammer, which may or may not exist in the Main.
26. I now beg to submit the following summary of conclusions arrived at by a consideration of the whole of the foregoing report:-
(1) The tests and analyses of the metal of the Pipes carried out before shipment were satisfactory.
(2) The whole of the Pipes supplied under Req. 254 were submitted to the specified test pressure of 1,500 lbs. per square inch, in the presence of my Inspector, and showed no signs of sweating.
(3) The analysis of the metal of the 5" Pipe returned from the Colony, indicates it to be of different composition to that analysed by me at the time of inspection, under Reg. 254.
(4) The microscopical examination of etched samples cut from the Pipes returned from the Colony, give no indication as to the cause of the bursting and sweating.
(5) The thickness of metal & other measurements of the Pipes returned from the Colony suggest that other Pipes, either obtained locally through Merchants or from the Crown Agents under Reg. 8 in the year 1900 (which Pipes
