must be made to fit closely together in the ditch (A, Fig. 351) ; 

 this is best accomplished by rotating the tile until it is in 

 place. The sewer tile (Fig.^352) is provided with bell end 

 or bell mouth, and the joints are made tight. Place the tile 

 in place so the direction of flow will be into the bell end ; place 

 the spigot end of each tile into the bell end of the preceding 

 tile as it is laid. A small piece of oakum or tarred rope forced 

 in between the spigot and the bell with a flat stick will make 

 possible a smooth job. Place cement mortar in the joint 

 after properly adjusting the tile. The use of a swab, as indi- 

 cated, is advisable. Place tile to a point 5' outside of building. 

 Cut, thread and fit pipe to discharge into the sewer that has 

 been laid. The depth to place this pipe and slope to give it 

 will depend upon the sewer outlet. 



342. Installing Kitchen Sink and Pump. 

 Requirements: To install a kitchen sink and pump so that 



water may be pumped directly from a well or cistern to 

 kitchen (Fig. 353). The installation of drain for this 

 sink is outlined under Sees. 338-341. 



Tools and Materials Needed : The tools needed for the project 

 are the same as in Sec. 334. The following materials 

 are needed: Pump, sink, trap and sufficient 1-1/4" 

 pipe to reach from pump at sink to cistern or well, as 

 illustrated (Fig. 353). Such elbows and couplings as 

 needed and a check valve for suction pipe. White or red 

 lead for making joints. 



Preliminary Instruction: 



343. Maximum Depth for Pumping Water. It must be 

 remembered that the vertical distance from cylinder of pump 

 to low level of water must be 25' or less to give satisfaction.
