Traps are an integral part of any waste system and are generally situated on the outlet of an appliance (to which the waste is attached).
The purpose of a waste trap is to provide a water seal between the waste water pipework and the internal environment of the property, thus stopping any foul air entering the building which would be both hazardous and unpleasant.
Running traps (or building traps) are traps located in the drainage piping that are not directly connected with a fixture. Many older homes had running traps in the building sewer, typically in the front lawn. These traps were designed to prevent sewer gases from entering the house. Modern homes do not have running traps since they were found to be unnecessary once effective venting systems were designed.
