Soil Vent Pipe Material

Drainage and waste disposal requires that the foot of a discharge stack should have as large a radius as possible and not less than 200 mm at the centre line.

Soil vent pipe material. Securing cast iron pipes and fittings together is. No other wastewater is discharged through this stack. Soil and vent pipes should run vertically if practicable and if they must be run otherwise they should be inclined not less than 1 foot in 40 feet. Soil stack is used to discharge waste from commode and urinals only.

Furthermore upvc is unaffected by coastal or industrial atmospheres or by the use of domestic cleaning agents. The dwv pipe is typically abs or pvc dwv rated plastic pipe equipped with a flashing at the roof penetration to prevent rainwater from entering the buildings. The soil pipe should be adequately supported by the floor joists avoiding any direct contact with either the floor decking or ceiling. We normally use 4 inches diameter upvc pipes as soil stack.

However today they are most commonly made from upvc. Use for main soil stack waste lines and vent pipes. Older homes may use copper iron lead or clay pipes in rough order of increasing antiquity. Traditionally soil vent pipes were made from cast iron.

Plastic has been seen by some as cheap and nasty but by the results it is found that plastic is not so cheap and nasty as it seems. Marley soil and vent pipes and fittings are manufactured from uv stabilised upvc which is tough and resilient. Where an offset has to be made in a soil or vent pipe it is advisable to use two obtuse angle or eighth bends b b as shown in fig. Cast iron soil vent pipe v s plastic cast iron is an old and more expensive way of fitting a soil stack.

All bends and curves should be made of large radius. Upvc the major material component is self extinguishing and will not support combustion. Once plastic came along it was found that there was money to be saved in the building industry. 2 all branch soil pipes running through a floor void above or below a habitable room should be wrapped in sound insulating material typically unfaced mineral fibre at least 25mm in thickness.

This stack runs vertically near the toilets of a building for the purpose of collecting wastewaters from commode and urinals.
