In-Line Air Release Valve 15mm
Used to release air from the drip line when the system is turned on, eliminating any air pockets, while also allowing air to freely enter the system when it is shut down. This ensures a vacuum does not draw debris into the drip line via the drippers.

The two main reasons for an air release valve are: 1. A means of releasing air from the drip line when the system is turned on. Eliminating any air pockets. 2. To allow air to freely enter the system when it is shut down. This ensures a vacuum does not draw debris into the drip line via the dripper outlets. This condition is known as “suck back”. Suck back can cause the drip line to collapse or potentially draw in dirt and block the dripper. This valve connection is normally located after the pressure reducer assembly as this is often the highest point in the drip system. It is important to install the valve at the “highest point” in the system to allow it to work correctly. If your tap & filter is lower than the irrigated landscape, ensure your air release valve is suitably located at the highest point.
