How To Design And Install Plumbing

Installation Procedure. The installation procedure of wallhung pedestal types of drinking fountain depends largely on the general design of the fixture. Drinking fountains are not standard and the method of installing them is distinctly individual.

Illustrative Example

In the working drawings or blueprints which architects prepare as a guide to the construction of houses there are seldom, if ever, any details of the required plumbing system given other than those which show the fixture symbols in their proper places and the location of one or more 8-inch partitions through which 4-inch soil pipes are to be run. Designing of the piping systems, therefore, must be done by the plumbing contractors before they can make estimates, bid on such jobs, or actually install the systems.

In this chapter, by means of an illustrative example, the design of a typical plumbing system is illustrated and explained. The house selected for this purpose is one of medium price, the like of which can be found in any locality throughout the country.

In the following, the blueprints for the typical house, the specifications for it, the roughing drawings, the illustrations used, and the design and installation of the system are explained in regular order.

Blueprints. The blueprints, upon which the illustrative example is based, are in an envelope attached to the inside of the back cover of this book and are designated and numbered as Plates 1 to 8.

All drawings indicating floor plans and elevations have been done according to the 1/4" - 1'0" scale. The detail drawings, which appear on some of the plan and elevation plates, are drawn to the 1/2"=1,0" or 11/2"=1'0" scales.

The blueprints are full size according to the scales used and are therefore exactly as they would appear if given to a plumbing contractor for purposes of estimating, bidding, and actual installation work.

A study of the various floor plans will show that the architect has indicated all fixtures and their locations and the partitions where soil pipes are to be run. The symbols used to indicate soil stacks in partitions are circles. In addition to the foregoing information the architect has shown the plans for the house sewer. The plans indicated by the architect should be followed exactly unless obstacles arise, in which case the architect should be consulted before any changes are made.

The blueprints, as indicated in succeeding pages, should be studied so that a perfect visualization of the entire house and its structural details can be obtained, all of which must be considered as the design of the plumbing system is being carried on.

Specifications. The function of written specifications is to supplement the blueprints. In other words, the specifications give instructions and explanations which are not or cannot be shown on the blueprints. Therefore they should be studied as carefully as the blueprints and every item noted with extreme care. For ex- ample, the blueprints show the locations of water closets, lavatories, etc., but only the specifications describe these items as to their quality, manufacturer, etc. In like manner the blueprints show tile, soil pipes, etc., but the specifications must be studied to learn the required quality, kinds, etc.
