The sewer drainage system and habitable area are separated by a body of water in the plumbing trap located directly below the floor waste and shower outlets. This body of water is not clean germ free water, it often contains bodily fluids such as faeces, urine, and a range of bacteria from ill and/or elderly patients. The plumbing drainage system requires venting to operate effectively and maintain trap seals, many systems throughout the world are defective, out-dated, or non compliant due to additions and or alterations to the system. Even in situations where the plumbing is compliant with the relevant codes, sewer gases can still make their way out of the drainage system into the habitable area due to the varying positive and negative pressures created within the pipework system. These pressure build ups force sewer gas bubbles to pop through the water seal leaving no evidence of a problem with the plumbing.
Evaporation of the water in the trap is one of the other causes of allowing the sewer gases to make their way out of drainage pipes. This is common in holiday homes, hotel rooms, plant rooms and premises that are infrequently used.
