air admittance valves ventapipe ventapipe 100 and ventapipe 50 application ventapipe 100 and ventapipe 50 air admittance valves are for use in above ground drainage systems they are designed to â–  provide a means of ventilation to the drainage system under conditions of reduced pressure when ventilating pipes are terminated inside buildings in accordance with bs en 12056-2:2000 air admittance valves ventapipe operation the two diagrams illustrate how ventapipe functions the valve diaphragm lifts and allows air to be drawn into the system when it is subjected to negative pressure on cessation of negative pressure the diaphragm returns to the closed position thereby preventing the escape of foul air into the building the valve is designed to open and close spontaneously when required thereby allowing a supply of air to adequately ventilate the system thus ensuring a smooth discharge valve open approval approved document h of the building regulations 2000 2002 edition requires that

section 6 quality certificate â–  air admittance valves should be removable to give access for clearance of blockages â–  air admittance valves can indicate the probability of blockages within the drainage system this can be indicated by high water levels in wc bowls following flushing and the slow draining of appliances upstream from the blockage â–  sizes and limitations upon the use of air admittance valves are subject to national and local regulations and practice if further detail is required check with the local authority building control office â–  kinetic ram guns should not be used to shift blockages on installations where air admittance valves are fitted as undue pressure and blowback may cause malfunction advantages â–  ventapipe enables ventilating pipes to be terminated inside the building thereby avoiding roof penetration â–  ventapipe allows greater flexibility in design of new drainage systems â–  ventapipe allows greater flexibility when
