New Handy Site On Plumbing

Having now completed this part and set it up, round in shape, proceed with burning in the bottom; having a hole or pit in the floor, deep enough for the hoop to go down level with the floor, placing it in perfectly level. Fill up with the sand inside and out rather slackly. When filled up within four or five inches from the top, ram it down for the other part quite hard on the outside, leaving the sand rather higher than the edge; then with a straightedge scrape off level with the edge of the lead. Now with a scribe take out the sand the thickness of the required bottom, plane the sand off with a trowel, and the work will turn out clean. The sand on the outside being up level with the edge, smooth off, and cut a bay all around to take the overflow, shake a little rosin around the edge; having the metal red hot, begin to pour as before, only this is a work for two or three persons if it is any size, as it must be done quickly, pouring the metal along the edge until it is properly burned down; when it is burned deep enough, pour a few ladlefuls all over the bottom, so as to get in a thoroughly fluid state; then with the edge of the trowel clean off the dross, leaving a perfectly bright surface. Let it remain to set. This will not require any filling up, as it is open to the air and shrinks; when set it may be removed, and if well burned it will be perfectly solid.

HOT WATER FOR DOMESTIC PURPOSES

In the accompanying sketches is shown the correct method of installing the piping for hot water for domestic uses. In work of this kind, the pipes must a!vvavs have a general upward pitch to the boiler, or tank. Care must be taken that there are no dips or traps, as this will cause hammering and pounding in the system. Sediment or draw off cocks must be placed at the lowest point, in order to thoroughly drain the system. Stops and check valves should not be used at all in this work, excepting, of course, the stop and waste on the cold water supply to the boiler.
