The bottle trap is an important part of the basin's plumbing as of course not only waste water passes through it but also due to a water barrier unpleasant smells do not pass back through it into the bathroom. When we use a bathroom wash basins, used water drains into the waste, then into the drainage pipe, and finally into the sewer, where a lot of other waste accumulates. Naturally, a lot of unpleasant and potentially hazardous gases accumulate throughout this process. What can we do to keep those bad odours from rising up via our drainage pipes and into our bathrooms This is where a bottle trap comes in handy. It's a vessel with a larger diameter than the plumbing pipe coming out of the basin. This vessel fills with water when water passes down. As a result, the trap is always partially filled with water. When sewer gases rise through the system via outlet pipes, they reach the bottle trap, where they are trapped by the water that has accumulated in the trap. The channel remains closed, preventing the return of gases. Any trap style comes in a variety of sizes, shapes, and finishes. Choose the type that best matches the finish and design of your other bathroom fixtures, as well as the bathroom design.
