Indicating Plumbing Fixtures On Plans

The symbols used on drawings to represent plumbing fixtures, bear a close resemblance to the outline of the fixtures represented, so that they can be distinguished from other fittings or apparatus in the building, and so the kind of fixture can be told at a glance. If special fixtures are to be used, or if for any reason the symbols cannot be made to represent clearly the fixtures they stand for, the name of the fixtures, or letters which will indicate what they are, should be added to the symbol to avoid ambiguity. It should be remembered that the object is not to make illustrations of the various fittings, fixtures, and apparatus, but only mechanical drawings which will indicate with sufficient clearness what they represent, so that no uncertainty will arise as to what they stand for. It will be noticed that straight lines and circles are used as much as possible in the symbols herein employed, so that any draftsman, with T-square, triangle and compass, can easily make any of them. It is good practice to draw the fixtures to scale on the plans, having each in its relative position, so the spaces they will occupy and their relation to one another will be apparent. By drawing fixtures to scale, it will be seen whether a group of fixtures can be installed in the space allotted to them. If not, they can be rearranged before inking them in on the drawings. The method of indicating a bath tub on plan is shown in Fig. 32. This symbol is so like the familiar outline of a bath tub that what it represents is suggested instantly to the mind. In Fig. 33 is shown the method of indicating a bath tub in elevation, and the likeness is so striking that there is no danger of mistaking what the lines stand for.

Lavatories are drawn in plan as shown in Fig. 34. The oval opening in the center of the rectangle, together with the two cocks sticking over the edge of the slab, so as to discharge into the bowl, leave no doubt as to the object of this symbol. The method of indicating the lavatory in elevation is shown in Fig. 35, where the outline of the bowl, and the cocks above it, tell unmistakably what these lines stand for.

Water closets are conventionally shown in plan as illustrated in Fig. 36, and in front elevation as shown in Fig. 37. The side view of a closet is illustrated in Fig. 38. These three symbols may be used to represent any type of water closet. Shower baths are indicated in plan by, the symbol shown in Fig. 39. In elevation, the illustration shown in Fig. 39 may be used. If, however, a shower bath is to be used in connection with a receptor, the outline of a receptor may be shown on Fig. 39 and the shower set over a receptor in Fig. 40. When used in combination with a bath tub, the two symbols, that for a shower, and the one for the bath tub can be combined.
