CP BOTTLE TRAP WITHOUT WASTE

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.
