It is equally wrong, ofcourse, to connect this over-flow with the soil-pipe, as isoften done. The proper out-let is into the open air, directthrough the wall, where itshould be cut short, and inorder to prevent wind blowingthrough the pipe or birds build-ing in it, a copper hinged flapought to be fixed on the dis-charge end. The accompanying sketch () shows the proper methodof connecting two or moreclosets with a common soil-pipe. In this case two closetsare shown, the upper one avalve closet, and the lower onea wash - down closet with Fig. 82, plumbers work. 125 So much for water-closet connections; we will consider laterthe more usual faults met with, some of which have already beenalluded to.

The last are the most cleanly,but they are very destructive of glass, which is very likely tochip against the hard surface unless greater care is observedthan servants usually exercise. Copper has a more cleanlyappearance than lead, and it is more durable. It is a mistaketo economise in the thickness of the metal used, as so little isrequired that the difference in cost between 8 lb. and 6 lb. lead,for example, is not worth any consideration, and is more thanbalanced by the saving in repairs.
