Innovative air admittance valves eliminate the need for external soil pipe termination, bypassing traditional positioning requirements and preventing foul odors from entering living spaces. These valves allow air into pipework to prevent pressure buildup while containing odors. They can be installed anywhere in the above-ground drainage system, at least 200mm above the highest wet entry point. Available in internal and external types, both must be installed upright. External valves use a push-fit rubber seal for soil pipe connections, while internal valves fit around the pipe's exterior. Both can also function as secondary rodding points. These valves save on labor and material costs and are safer than open vent pipes by eliminating the need for roof-level access during maintenance. They are fitted with environmental mesh for external installation, feature uPVC construction, a push-fit connection, and a 30.8Ltr/sec air flow capacity. Suitable for domestic and commercial use, they are demountable and reusable. The dual-fit connection is compatible with push-fit and solvent-weld systems. The rubber lining ensures fast, tool-free installation on 110mm male pipe. The female socket fitting accepts 110mm male pipe ends for a watertight joint. The one-way air valve opens under negative pressure to equalize airflow, then closes to block sewer gases and preserve water seals. This all-mechanical design has no moving parts, delivering silent, trouble-free performance. Easy vertical installation takes minutes in a ventilated, accessible spot at least 200mm above the highest flood level. The low-profile body suits various installations where roof venting is impractical. Manufacturer: LavaTap.
