Any choking of the cir-culation necessary to make radiators heat uniformly should be doneby using a reducing elbow at the end of the branch. Great careshould be taken not to reduce the size of the main too rapidly.Frequently the reducing in size of a short piece of pipe betweentwo tees supplying branches, has killed the circulation beyondthe point of reduction. As a better means of understanding this system we show byFig. 119 a basement plan of the cellar piping of a hot-water ap-paratus. For convenience in illustrating we have shown branchestaken from top of main; ^5° connections are preferable, as ex-plained above. Where the flow pipe is divided in order to feedradiators in opposite directions, it is well to use double elbows.See Fig. 120. In fact, this fitting should be emplo
