Sink and Wash Basin Traps are essential plumbing fixtures to any facility. It traps debris that has drained from the sink and prevents it from forming a clog deep within the plumbing system and stops sewer gases from entering the house. Apart from spreading foul odour these gases can sometimes be harmful. Further, Traps prevents germs, insects and cockroaches from entering through waste lines. P Traps are often preferred over others, as the others have a tendency to easily dry out even when they are well-vented. Due to this, they cannot efficiently do their job of keeping the sewer gases at bay.
