USE OF BRASS PIPE FOR SERVICES AND SPECIALLY DESIGNED GOOSENECK
About three years ago the Hackensack Water Company commenced using brass pipe on all of its house service installation work between the street main and the curb, and also in renewals of old services which had failed. The smallest size used is 3/4-inch, but for 1-inch work brass pipe is also used and in sizes larger than 1-inch, cast iron is used exclusively. When we first started this work we used the regular brass pipe, I.P.S. and had some trouble with it on account of it being too hard and brittle. Being non-flexible, it broke transversely m’uch the same as would a glass tube. In the next purchase semi-annealed pipe was specified and with this no trouble has developed.
Before purchasing pipe for this year’s work (1925) I obtained from Mr. Schneider, representing the Copper and Brass Research Office of New York City, a copy of a specification prepared by the American Society for Testing Material covering brass service pipe requirements and asked for bids for 135,000 feet, in January. Part of the pipe has been received and is being used. The pipe is I.P.S., is very flexible, threads and cuts well and comes in 12-foot lengths. I fully believe it will meet requirements in every way.
Brass pipe may not be quite as cheap as galvanized iron, lead lined, galvanized iron or black, but it is less costly than lead of the same size. Three-quarter-inch lead A. A. weighs 3 1/2 lbs per foot and with lead pipe at 10c per pound, the cost is 35c per foot. Three-quarter-inch brass weighs 1 1/4 lbs. per foot and costs 18 3/8c per pound or 23c per foot.
We are using a head gooseneck between the corporation tap and the point where the brass pipe begins. Until January 1st this year, these goosenecks were made up by local plumbers. The 90º tail piece of the corporation tap and a brass soldering nipple at the other end of a piece of lead pipe 20 inches long being wiped joints. These goosenecks were expensive, frequently leaked and were generally unstatisfactory. Our master mechanic. Hugh Davis, suggested doing away with the wiped joints and making cup joints instead. This is done by driving a former into the ends of a piece of lead pipe and soldering in the tail piece at one end and a special coupling at the other, leaving when finished a female thread to receive the pipe and no soldering nipple is used. We arc now making these in our own shop for about 80c apiece less than the old style and each completed piece is tested to 300 lbs. pressure before going into stock. They are exceedingly satisfactory. The illustrations show the old style and new style goosenecks.
