Valve for venting the main drain stack

Patented and launched on the market in 1975, MAXI-VENT is a brilliant and effective solution ensuring the correct admission of air into the drainage system and preventing the need to extend the stack or any other line outside the building. The MAXI-VENT vent valve is simple and quick to install on the main drain stack, and is usable in a wide range of applications: in a service cavity, in an attic, outside the roof, on a balcony or built into the wall, with its own air intake grille. Complete with its own clamp, the MAXI-VENT valve may be installed, in a vertical position only, on 75, 90 and 110 millimetre diameter pipes. The air admission system has a capacity of 32 litres of air per second, and, once installed, requires no further maintenance. Installing the valve within the building prevents the need to extend pipes out of the building, which frequently release unpleasant odours and which, if situated near windows or balconies, can be an unhygienic nuisance.
