In any irrigation system trapped air bubbles can damage pumps (via cavitations) and disrupt the flow and pressure in the system. Installing an air relief valve in an irrigation system allows the release of large volumes of air as water flows through the pump, pipes and filtration system, either along or at the ends of the main line. A continuous relief valve insures that pockets of air are continuously released during operation, reducing vacuum effect at shutdown.
Installation for Air Relief Valve A157
To install an air relief valve, ensure you have a 1" FPT tee at the highest point along the pipeline or upstream of the valve manifolds. The air relief valve should thread into a 1" male pipe thread. It is important to install the air relief valve at the highest point of the system layout or near the pump and filtration stations to allow it to work correctly. If your water inlet and filter are lower than the irrigated landscape, ensure your air relief valve is suitably located at the highest point.
