2. WHAT IS A DRAIN WASTE SYSTEM?
A drain waste system is a network of large pipes that take the water used in sinks, toilets, and tubs out of the house.

3. FUNCTIONS OF THE DRAIN WASTE SYSTEM
A drain waste system maintain neutral air pressure in the drains.
Allow free flow of water and sewage down drains and through waste pipes by gravity.
A P-trap traps the debris that has drained from the sink and prevents it from forming a clog deep within the plumbing system, and to stops sewer gases from passing into the home.

4. THE PROCEDURES INVOLVED In ASSEMBLING THE DRAIN WASTE SYSTEM
Steps involved in the assembly/installation of a drain waste for a sanitary face basin.
Step 1- Sanitary Face Basin in position
Step 2-Plumbers mate putty is applied to the drain strainer body.
Step 3- Strainer body is then set into the drainage position of the sanitary face basin.

5. Continued PROCEDURES INVOLVED In ASSEMBLING THE DRAIN WASTE SYSTEM
• Step 4- The lock nut is then tightened to the strainer body firmly, using a groove joint pliers and a needle nose pliers. • Step 5- After that the thread seal is wrapped clockwise around the threaded area of the strainer body and then the tail piece is tightened onto it. • Step 6- P trap is attached to the tail piece, adjusting the position or height to align with drain pipe outlet. • Step 7- Coupling nut on the P trap is tightened to the tailpiece. • Step 8- A 90 degree elbow is joined to the outlet fitting, using a short piece of measured pipe and solvent to stick them together
