Why Do We Need Bottle Traps for Wash Basins?
The Bottle Trap Below the Basin
Have you ever noticed the bottle trap that sits right under the sink or basin? We all tend to see and choose the most beautiful basins and taps for our bathrooms, but never notice that bottle trap, a basin accessory that does so much more than just making the bathroom look great.
What Is a Bottle Trap and Why Do We Need It?
The bottle trap is an essential element of the basin's plumbing that keeps the bathroom hygienic and odor-free. When we use the basin, the used water goes down the basin waste, into the drainage pipe, and then into the sewer, where a lot of other waste and dirt is accumulating. Naturally, that accumulation involves a lot of nasty and potentially harmful gases. What is there to prevent those foul smells from flowing back up through our drainage pipes, through the wastes, and back into our bathrooms? (Ewww! Sounds bad, doesn't it?) This is what a waste trap (bottle trap, P trap, or U bend) is for.
We need those traps to prevent gases from contaminating bathrooms, thus helping maintain hygiene in the bathroom and keeping it safe for us.
How Does a Bottle Trap Work?
It is a vessel which has a bigger diameter than the plumbing pipe that comes from the basin. When water gushes down, this vessel fills with the new water. Thus, the trap always remains filled with a certain amount of water.
When the sewer gases waft up the system through the outlet pipes, they reach the bottle trap, but here they find their way sealed with the water that has collected in the trap. The passage remains closed and doesn’t allow the return waste and gases to enter.
The Same Basic Concept Works for Other Plumbing Fixtures
You must be wondering if the same thing can happen with the bath tub, shower, and (worst of all) the toilet. Imagine those gases floating out of the toilet and into your bathroom. Good thing the toilet has an inbuilt trap that functions exactly like the bottle trap and prevents sewage gases from returning. The shower and the bath, too, have similar systems.
Choose the Most Suitable Trap for Your Basin
There are various sizes, shapes, and finishes available in any trap style. Choose the most appropriate model to match the finish and design of the other bathroom fittings and sync with the bathroom decor.
