Early in the history of indoor Plumbing, waste drainage was a simple matter; a pipe containing the wastewater led to sewer. Before long, the noxious gases that were created by the anaerobic conditions in the sewer became a threat to the health of those indoors. Thus, the trap was invented to block the pipe so that gases could not pass. However, as moving water filled the pipe downstream from the traps, the mass of water acted as a plunger, creating higher pressure in front of it and negative pressures behind. The positive pressures might force sewer gas through the water in other traps; worse, the negative pressures could suck (or siphon) the water from the trap, leaving it open to gas passage. A way to deal with these pressures was through the installation of vents so that the suction would draw air down through the vents rather than water from the traps .
