Understanding P Traps

Gravity plays a crucial role in the functioning of plumbing systems, particularly in how water moves through pipes. The P trap design effectively prevents siphoning, ensuring that water remains in the trap to block sewer gases from entering living spaces. When a toilet flushes, water flows through the trap, allowing waste to exit while maintaining a barrier against unpleasant odors. This ingenious mechanism highlights the interplay of gravity, water, and design in modern sanitation.
