Modern plumbing illustrated : a comprehensive and thoroughly practical work on the modern and most approved methods of plumbing construction ... . w it, and the methodshown is probably the most satisfactory. It will be noted that in thismethod the course of the circulation of hot water is continuous, thehot water from the furnace passing through the range water-front,thence to the boiler and to the fixtures, and, when it has cooled,returning to the furnace coil. Two lines of circulation are shown,each being brought together on the return. The use of circulating pipes, if properly installed, insures a con-stant supply of hot water close to the fixtures supplied, and naturallyobviates the necessity of drawing off a long line of cold water beforethe water will run hot, as must be done in work unprovided withcirculation. This saving in the use of water is a matter of importance wher-ever water is metered or limited in amount. Whenever the house supply is from an attic tank the hot-watersupply must be under tank pressure, in the use of which system anexpansion pipe is necessary.
