To prevent sewer gases and odors from coming out into your HVAC system and permiating your home.
Here are the answers: Drainage Air Test. The air test is a quick, convenient method we can use to test single pipes and drain runs. Water Drop Test Drainage. Drainage Test Certificates.
A toilet has a built in trap thus NO othyer trap is needed and will cause air bound systems and many problems with improper drainage
it traps air inside to slow it down
The quilt traps heat under you, and the lighter it is, the colder you'll be because it won'ttrap as much hot air. The cold air it traps turns into warm air because there is alot of hot air and not that much cold air, so the cold air warms up.
an example of an air insulator could be the fur of an animal, it traps a layer of air to keep them warm
Temperature Inversion
Portable air conditioners that do not require water drainage offer the benefit of convenience and ease of use. They eliminate the need for constant monitoring and maintenance associated with draining water, making them a hassle-free cooling solution. Additionally, these units are more versatile as they can be placed in various locations without the need for a nearby water drainage outlet.
Chest drainage therapy involves the removal of air, blood, pus, or other secretions from the chest cavity.

Air particles can be trapped by various materials such as filters (like in HVAC systems), nets (used in air filtration systems), and physical barriers (like in a sealed container). These traps prevent the movement of air particles by obstructing their path, allowing cleaner air to pass through.
An air conditioner that is spitting probably has a blockage in its drainage. Because colder air cannot hold as much water as warmer air, air conditioning causes water to condense out of the air. Algae thrives in the drainage of the condensation, and a colony of algae can grow to the point that the drainage is blocked. To prevent that, pour a cup of bleach into the drainage every month or two. If the condensation drains through a tube or pipe, such a blockage can be easily blown out (just don't touch your lips directly to the tube or pipe).
The purpose of plumbing vents in a building's drainage system is to allow air to enter the pipes, preventing suction and ensuring proper drainage flow.
