What is Trap ? | Its 11 Types
Mostly in minds, questions occur what is trap? The short and simple answer is, “The trap is a plumbing device used to prevent bacteria, smell, and insects from entering our home.”
Every water fitting and appliance has a drain line to flow out the water, and we must have a trap in the pipe that seals the drain.
A seal is essential to keep the environment fresh and prevent the sewer gasses from entering the building. In addition, we can see traps equipped with varied plumbing fixtures such as toilets, sinks, washbasin, and bathtubs.
And with the help of several connections, we can install the trap, which is we generally locate within a plumbing fixture.
The traps are designed to prevent the sewer odors from entering the house through the plumbing fixture, and thy wastewater gives seal in traps.
We use fixtures every time and flush out the water forming the trap seal and replacing it with new water.
It is a carefully engineered system. The traps are designed to be self-scoring so that they do not collect debris yet retain water to form the seal. Therefore, the velocity with which waste moves through the trap is essential.
