Drainage ventilation expert Studor has developed the Trap-Vent, a combination of a water trap and an air admittance valve (AAV). It can be retrofitted to an existing bathroom and is also suitable for small group venting in, for example, hotels, care homes and hospitals. It protects the water trap seal between the drainage system and the room, stopping bad odours and pathogens escaping from empty traps.
The trap features a 50mm water seal and an integral AAV. It reduces the need for secondary ventilating in small fixture groups and replaces conventional S traps and P traps. It is height adjustable for fully flexible installation, has integrated self-cleaning, and is suitable for bath and shower rooms, providing solution for problem solving in new builds as well as the retrofit market.
Studor’s UK MD Stephen Taylor comments: “The Trap-Vent comes with a lifetime guarantee and also reduces siphonage noise, providing a 20dB noise reduction compared to conventional traps. Furthermore, it allows freedom of design for engineers and architects to enable multiple drainage fixtures to link together. It is also highly styled, so eminently suitable for installation in environments where aesthetics is of high importance.”
