New Handy Site On Plumbing

As it is impracticable to show sketches which will comply with every ordinance, sketches are given showing correct and sanitary installations in the two general classes.

In Fig. 43 is shown the waste and vent connections pertaining to the plumbing in an ordinary dwelling, in accordance with the general run of plumbing ordinances, which specify that the waste from sinks must be carried to a catch basin before entering sewer.

A. 2" extra heavy soil pipe from catch basin in yard to a point about 12" below roof.

B. 2" galv. iron, or extra heavy soil revent pipe from increaser F. near roof, to a point in soil pipe, C. below lowest fixture revented. The revent from each individual trap should be carried up to a point at least 3 feet above floor before making connection with vent line. This is to prevent the fixture from wasting through the vent pipe, in case of stoppage in waste or soil pipe. In some cities the ordinances allow the connection of revent "B" to stack "C" at any point above the highest fixture wasting into stack.

C.4" extra heavy soil pipe stack, from sewer in basement to a point about 12" below roof.

D. House sewer of 4" extra heavy soil pipe from catch basin to a point about 10 feet outside of foundation wall. From this point to sewer in street, the sewer may be 6" salt glazed sewer pipe.

E. 2x4 extra heavy increaser 30" long.

F. 4x5 extra heavy increaser 30" long with 2" side cutlet for revent pipe.

G. 11/2" galv. revent pipe to lavatory trap and bath trap.

H. 2" galy. revent pipe to 4" lead bend or to crown of doset trap. Some cities compel the use of extra heavy soil pipe for "G" and "H." In cases where but one fixture wastes into stack, the revent is unnecessary. For instance, note that sink trap in sketch is not revented as the sink is the only fixture wasting into stack "A." In cases of this kind, the fixture should not be more than 5 ft from stack.

J. 4" lead bend for closet waste.

K. and L. 11/2" lead pipe, 3 lbs. per ft from bath tub to drum trap, and from drum trap to lead bend.

M. 4" lead drum trap.

N. connection of revent to 4" main stack.
