The primary function of traps is to:
prevent sewer gases from entering buildings by providing a water seal that blocks the gases
allow sewer gases to enter buildings
increase water flow in pipes
reduce water pressure in pipes
A water seal is a barrier of water in a trap that prevents sewer gases from passing through. Why is it important?

It allows sewer gases to pass through.
It is used to increase water pressure.
It is a decorative feature.

Above ground drainage involves specific sizes of waste pipes, clipping distances, and gradient fall.
Above ground drainage is only about the sizes of waste pipes.
Above ground drainage does not involve clipping distances.
Above ground drainage is unrelated to gradient fall.
What are some important aspects of sanitation that should be considered in daily life?
Personal hygiene, waste disposal, and clean water access
