Combination Vent and Drainage Connections
During the last decade or two, great advancements have been made in plumbing and drainage In fact, what was considered pertection only a few years ago, is now obsolete
Amongst all the improvements, the so-called F & W Combination Vent, Re-vent and Drainage fittings easily take the lead As all re-vent connections to the soil stack are connected by means of 45° and all so-called pockets are done away with It absolutely prevents any rust or sediment to lodge in the bends and thereby, after a few years, close up the recent as was the case in the old style fittings. The F & W system is now considered the perfection and is compulsory in several of the largest cities in both the east and west

"Fig B" shows roughing in for a two, or more, stories flat building Here, of course, kitchen sink, bath tub, water-closet and lavatory are on one floor and roughing in repeated for as many stories as the building contains The dotted lines, where marked "Plan of fixtures," shows a partition wall and the different fixtures
"Fig C" is an elevation of roughing in for a batter of double water-closets as used in schools, office buildings, factories and public buildings
For houses in towns and country places, where there are no sewers, the soil from a full line of fixtures can be taken care of in a perfectly sanitary way by building a cess pool of either brick or wood, 25 feet or more from the rear of the building If the cess pool is of wood, holes of 11/2" or 2" diameter should be drilled on about 4" or 6" centres all the way around and for a height ot three to four feet If of brick, use good hvdraulic cement mortar and leave a 2" opening at frequent intervals and to a height slightly below the soil pipe A run from the cess pool can be made to distribute the water over a larger area If such a run is made, lay the pipes without any cement joints, thereby letting the water run out at every joint.
