The Worcester Bosch part is located within the condensate trap section. The condensate trap holds the discharge which accumulates in the primary heating and cooling system. This is caused by the fluctuations in the temperature and pressure within those systems. A discharge pipe connected to the condensate trap then allows any held water passage out of the property. The water inside a condensate trap can be mildy acidic due to carbon dioxide from the combustion process dissolving in the water.
