to make the waste in more than one piece, use a slip joint ; that is, a joint 

 giving about 3 inches of lap that you can slip together in its place and 

 solder after lixing. Let the waste-pipe di.scharge into a half-round stone- 

 ware drain. Should the closed drains be used, let the length between 

 them and the waste-pipe be a half-round open drain. This will form a 

 disconnection and prevent the drain ventilating into the house, to a far 

 les.ser extent tlian it otlicrwise would.

In cases where septic tanks, .sewerage system, &c., are in use, special 

 disconnecting traps must be used, and they play a very important part 

 in preventing sewer gas from finding its way into the dwelling. This, 

 however, need not be considered, unless it is intended to instal a septic 

 tank system; then, by all means, have the waste pipes completely trapped 

 and disconnected.
