How Does a Plumbing Trap (P-Trap) Lose Water? Plumbing traps, commonly called P-traps, are an important part of your plumbing system. They are designed to constantly hold water in the drain to prevent sewer gas from escaping into the house.
Because of its shape, the trap retains some water after the fixture's use. This water creates an air seal that prevents sewer gas from passing from the drain pipes back into the building. Essentially all plumbing fixtures including sinks, bathtubs, and showers must be equipped with either an internal or external trap.
The main purpose of a P-trap is to trap noxious sewer gases inside the wastewater system so that they can't rise back up through the drain, and it is the shape of the trap that makes this possible. Running your sink obviously flushes water through the trap and down into the drain line.
The water trap seal is the single most important fitting on the drainage network as it prevents the spread of diseases by limiting human exposure to pathogens and allowing the solid and waste transportation system safeguard public health.
The Uniform Plumbing Code states that P-traps are required for every drain line that carries wastewater into the plumbing vent-waste drain system. This means that every sink, shower and floor drain should have a P-trap that connects the drain to the drain line.
However, as a general rule of thumb, all water-using appliances and fittings within a property must have a waste trap to provide a water seal to the drains. Here we explain what waste traps are and how they work in layman's terms.
Not only is the trapped water in a 'P-trap there to keep sewer gasses from floating into the room, the 'P' shape of the trap also 'traps' many things that commonly go down our drains, like hair, or anything heavy that might fall into a sink; like a ring.

tl;dr The seal is the rock layer above that will not allow passage of the hydrocarbons from below. The trap is the configuration of the reservoir, the seal and other geologic features that prevent the hydrocarbons from migrating around the seal.
There are traps in every drain because any connection that leads to the drain system is also a possible outlet for sewer gas. Even your toilet has an internal trap shape to its porcelain configuration that serves exactly the same function.
The function of a trap is to prevent the escape of foul gases inside and outside the house. The effectiveness of trap naturally depends upon the depth of the water seal. The greater the depth of the water seal, the more effective is the trap.

If a P-trap has become empty of water or dried out for any reason, it will allow the sewer gas air inside the waste pipes to come pouring into where we live and work. Every P-trap on every drain needs to have a vent that protects it; that's what all those pipes are that we see sticking out of our roofs.
A toilet trap sounds like something you'd want to steer clear of, but it's actually a key component of a toilet drain that helps keep sewer gases out of your home.
