Studor drainage solution avoids roof penetrations

Drainage ventilation with no roof protrusions has been achieved at the €130 million Monselice Hospital in Italy using Studor Maxi-Vent air-admittance valves to cap as many stacks as possible. The valves fit discreetly within the roof space. The architect’s vision was for a ‘wave-effect’ building with no roof protrusions to mirror the sinuous lines of nearby hills.

Daniel Rath, Studor’s UK technical sales manager, explains, ‘The Maxi-Vent protects the trap seals within the drainage systems by allowing the intake of air so that each soil pipe can maintain the right level of pressure within the system. This is critical in a hospital environment, ensuring there is no cross-contamination from the drainage system into the habitable space.

‘Maxi-Vents eliminate the need for any roof penetrations, thus reducing the amount of pipework required, saving both time and money.’

Over a hundred Maxi-Vents were installed, which as well as being the only technical and legally recognised solution to the drainage ventilation needs, offered significant environments benefits in reducing the hospital’s environmental footprint.
