Can HypAir Balance air admittance valve be installed outside?

No. The HypAir Balance vents are not designed to be exposed to Ultra Violet Rays.

Can the HypAir Balance AAV be installed inside a closed wall and what are the maintenance requirements?

No, the HypAir Balance cannot be installed inside a closed wall. Remember, if the HypAir Balance has to be installed in a wall cavity, it is necessary to use the wall box with a louvered face plate. This allows the AAV to have access to the fresh air, and also allows as an access door. The HypAir Balance requires regular maintenance, taking into consideration that AAV is a mechanical device and like all mechanical devices, a maintenance routine should be set up to secure AAV is functioning properly.

Increased comfort and safety

The elements of the external sanitary system guarantee the proper drainage of rainwater, thus increasing comfort and safety. The system comprises of an External linear dewatering system - designed for removing water from areas near the house, pedestrian traffic areas, bicycle routes, and as sports and recreational areas. Our non-return valves are designed for installation on horizontal pipe sections in sewage manholes, either inside or outside buildings. They provide anti-flooding protection and help to protect buildings against flooding due to rainwater travelling back down the sewage system. Debris gullies provide a connection between the gully system in the building and the waste-water system. Rainwater is effectively removed, protecting the building against rainwater accumulation and damage to the foundations.
