Materials used for waste and discharge systems The materials available for waste pipes and soil and vent stacks are listed in Table 7.1. A clearance of 30 mm should be left between external pipes and the structure to allow free access and for painting. Secure bracketing to the structure is essential and allowance for thermal expansion should be made. Pipes passing through walls or floors should be sleeved with a layer of inert material to prevent the ingress of moisture into the building and provide the elasticity required for thermal movement. This is particularly important with plastics.
216 Soil and waste systems Table 7.1 Materials for waste and discharge pipework. Material Application Jointing Cast iron 50 mm and above vent and discharge stacks Lead caulking with molten or fibrous lead; cold compound caulking Galvanized steel Waste pipes BSPT screwed Copper Waste pipes and traps Compression, capillary, silver solder, bronze weld or push-fit ring seal Lead Waste pipes and discharge stacks Soldered or lead welded ABS Up to 50 mm waste and vent pipes Solvent cement and push-fit ring seal High-density polyethylene Up to 50 mm waste and ventilating pipes and traps Push-fit ring seal and compression fittings Polypropylene Up to 50 mm waste and ventilating pipes and traps Push-fit ring seal and compression couplings Modified PVC Up to 50 mm waste and vent pipes Solvent cement and push-fit ring seal Unplasticized PVC Over 50 mm soil and vent stacks; vent pipes under 50 mm Solvent cement and push-fit ring seal Pitch fibre Over 50 mm discharge and vent stacks Driven taper or polypropylene fitting with a push-fit ring seal Note: ABS, acrylonitrile butadiene styrene; PVC, polyvinyl chloride. Testing Inspection and commissioning tests on drainage installations are carried out as follows. Inspection During installation, regular inspections are made to check compliance with specifications and codes. Particular attention is given to quality of jointing, security of brackets and removal of swarf, cement or rubble from inside pipe runs. Air pressure Prefabricated waste pipe systems will be factory tested before delivery to the site. The complete system will be tested on completion by filling the water seals and inserting air bags, expandable bungs, into the ends of stack pipes. A rubber hose is inserted into the vent stack through a WC water trap. The air pressure in the stack is hand-pumped up to 38 mm water gauge, measured on a U-tube manometer. This pressure must remain constant for 3 min without further pumping. Soap solution wiped onto joints will reveal leak locations. Smoke Existing stacks can be tested by the injection of smoke from an oil-burning generator or a smoke cartridge, provided that it will not cause damage to the drain materials. This is less severe than the air test, as smoke pressure remains low and damage from the test itself is less likely. Suitable warnings must be given to the occupants of the building.
