WATER WORKS PRACTICE
The Board of Water Commissioners of Dover, N. J., has a rule governing the repair or changes of service pipes by plumbers, stipulating that an additional shut-off cock be placed near the meter to prevent damage to the meter. Plumbers in the past have been careless and when the water was shut off the back-flow caused serious damage in case the water from the boiler should drain into the meter, warping the delicate mechanism.
Some ingenious contractors constructing a cast-iron water pipe line lor the town of Preston, Cuba, bent cast-iron
pipe to be used around curves in a canyon in the absence of special bends.
Through somebody’s oversight, no bends or sleeves were ordered with the pipe when it was bought, and as it might have taken a month or so to send up and get additional specials, the local engineer decided to bend some of the straight pipes. The pipes were bent to various radii, the shortest being 50 feet. A cradle of old rails was first constructed with the desired amount of curvature.
About one foot at each end of the pipe was left outside the fire, to prevent collapse of the pipe, and a fire of hard wood was built under and around the remainder of the pipes. Six or eight pipes were bent at a time. In one and one-half to two hours after starting the fires the pipes were hot enough to bend, and settled front their own weight to the cradle prepared to, receive them.
The control of water service to consumers at St. Louis, Mo., has been assumed by the Inspection Branch of the Water Division. This control was formerly tinder the jurisdiction of the Water Rates Division of the Collector of the Revenue, and the work in connection therewith consisted of shutting off and turning on of water service on account of delinquent accounts, vacancies, new consumers or such other causes as were incident to the collection of the water rates revenue. In order to handle the work required by the Collector of the Revenue and the Assessment Section promptly, and to render efficient service to consumers, it became necessary to decrease the usual frequency of inspection of inside plumbing fixtures by house-to-house canvass.
Usual supervision is made of all new work done by the Public Service Corporations where the nature of the work required opening trenches which were located so as to expose or interfere with taps, service pipes or water mains. Included in such work is the inspection of the services interfered with by the construction.
Examination of all services used exclusively for fire protection is included iu the work of this Branch, and all valves and hydrants are rescaled wherever the seals are found broken or where they show evidence of having been tampered with.
Careful analysis is made of all pressure or service complaints received from consumers, and every effort made to eliminate the trouble in those cases where the Division is at fault. In most instances the reasons for the complaint can be traced to defective plumbing. The consumer is so notified and suggestions as to the remedy are offered.
