CHAPTER IX 

 HOW WASTES ARE REMOVED FROM THE HOME 



Problems. i. To understand how wastes are removed 

 from the body. 



2. To understand the system of waste removal needed for 

 the home. 



3. To learn how the various plumbing fixtures work. 



4. To see how a septic tank does its work. 



Experiments. i. To see how a siphon works. 

 2. To understand how a flush tank works. 



Project I. To PREPARE MYSELF TO KEEP THE HOME PLUMBING 



SYSTEM IN ORDER. 



This involves a thorough study of the devices, piping, etc. in the 

 home. Diagrams should be made of pipe systems showing valves 

 and cut-offs, etc., and of individual devices, as traps, bowls, toilets, 

 flush tank, and faucets. 



Study the devices seen at plumbers. Talk with men who know 

 how these devices work. Find out how to remedy a clogged sink drain, 

 toilet, and wash bowl drain. Learn what to do when pipes are frozen 

 and when a large leak occurs, and how to repair your faucets. Be 

 sure you know how to shut off water, gas, and electricity from the 

 entire house. 



A collection of pictures of plumbing devices cut from magazines 

 and described in your own words will make a splendid section in your 

 final report of this project.
