To stop smells entering a building, the open end of the ventilating pipe should be at least three metres to the side of, or extended to 0.9m above, any opening into a building. If the drainage is already ventilated, additional ground floor appliances (eg. a WC and washbasin) may be connected directly to the drain without a ventilating pipe. Branch pipes can also discharge into an unventilated "stub stack" as long as they are only used to connect ground-floor appliances. The vertical drop to the drain must not exceed 1.5m from a WC and 2.5m from a waste appliance. The head of the drain should be vented to the atmosphere. The maximum loading of a stub stack is 5 litres/second. Water is the prime cause of deterioration in building materials and constructions and the presence of moisture encourages growth of mould that is injurious to health. Ground water can penetrate building fabric from below, rising vertically by capillary action. The effects of this rising damp are immediately recognisable. There may be horizontal ‘tidemarks’ sometimes.
