Plumbing Traps what are they?

A P trap is that u shaped pipe under the sink. Its purpose is to hold a little water in the trap in order to keep sewer gases from entering the building. Sewer gasses can be dangerous so we don’t want them in the home. In order to keep the sewer gasses out and sewage flowing smoothly code officials developed rules that must be followed for proper drainage and safety. In addition to traps; vents are needed to keep pipes from gurgling and to help liquids to flow through the pipe. If P trap is not installed properly eventually the trap will clog up with debris and water will not drain properly.
