McAlpine Air Admittance Valves

McAlpine Air Admittance Valves

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 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

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

Approval
Approved Document H of The Building Regulations 2000 (2002 edition) requires that Air Admittance Valves comply with BS EN 12380:2002
All McAlpine Ventapipe Air Admittance Valves listed have been independently tested by the LGA Testing House and certified as being compliant with BS EN 12380:2002 and designated as Class A1

This means that Ventapipe can be installed:
Above or below the flood level of connected appliances
Ventapipe has an operating temperature range of -20ºC to + 60ºC
Ventapipe was granted A1 Classification without the necessity of a polystyrene cover
Ventapipe have been tested at -250 Pa for their Air Flow Capacity and the Flow Rate is stated alongside each Valve listed

Quality Certificate
The LGA Quality Certificate certifies a product’s high and consistent quality. It confirms the performance capability (functional characteristics, wear and tear and service life) of a product and therefore its comprehensive quality. Annual production inspections ensure its consistent quality. Whenever the LGA Quality Certificate is on a product it ensures it has been thoroughly tested

Advantages
• Ventapipe enables ventilating pipes to be terminated inside the building thereby avoiding roof penetration
• Ventapipe allows greater flexibility in design of new drainage systems
• Ventapipe allows greater flexibility when installing additional appliances to existing drainage systems
• Ventapipe eliminates problems of freezing associated with external pipes
• Ventapipe is suitable for use with either plastic or metal pipes
• Ventapipe offers cost savings in both material and labour
Information for General Guidance only
• Underground foul drainage should be ventilated by a flow of air. A ventilating pipe should be provided at or near the head of each main drain
• An open ventilating pipe, without an Air Admittance Valve, should be provided on any drain fitted with an intercepting trap, particularly on a sealed system and on any drain subject to surcharge
• Air Admittance Valves should not be used when the soil stack provides the only ventilation to septic tanks or cesspools
• Air Admittance Valves should not be used where there is no open ventilation on a drainage system or through connected drains and therefore alternative arrangements to relieve positive pressures should be considered
• Air Admittance Valves should not be used outside buildings or in dust laden atmospheres. They should be located preferably in a non habitable space, such as a duct or roof. The space should have adequate ventilation and be accessible for maintenance
• Air Admittance Valves should be removable to give access for clearance of blockages
• 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
• 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
• 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

Ventapipe 15, 25, 40 and 50 Application
VP15, 25, 40 and 50 Air Admittance Valves can be used as alternatives to Anti-Syphon and Resealing Traps to ventilate the waste pipe system in order to overcome problems such as noisy discharge or loss of trap seal
