Internal Soil Pipe Air Valve Installation

An internal soil pipe air valve must be installed in a suitable location within the drainage system. Check the connection arrangement, installation position, access for maintenance and relevant building requirements before fitting. The valve admits air to relieve negative pressure but does not provide an open route for releasing positive pressure from the drainage system. It should not automatically replace an open soil vent terminal in every installation. Follow the installation instructions supplied with the product. This valve is described for internal use and should not be installed externally without specific confirmation of suitability.

Choosing the Correct Air Admittance Valve

Check the nominal pipe sizes and actual jointing arrangement before purchasing. Push-fit and solvent-weld connections are different, and the exact connection arrangement must be confirmed for this fitting. The 110mm 82mm admittance valve is intended for compatible soil ventilation applications where its connection dimensions and installation requirements are suitable.
