Sub Surface Irrigation Air Release Valve Assembly
| Component Assembly For Sub Surface Drip Irrigation Systems Continuing with our Drip Zone Assembly we will now look at the components required for assembling an Air Release Valve for a Sub-Surface Drip Irrigation System:
Air Release Valve Assembly The Air Release Valve is often overlooked but is a valuable component for maintaining a worry free sub-surface drip irrigation system. The air release valve allows air to escape the system on it's initial start up until the system is full of water. Once full the valve automatically closes until the cycle is finished and then allows air to flow back into the system. The air release valve helps in avoiding clogging of emitters due to back suction and will extend the long term life of the system. It also helps to avoid water hammer at the start of a watering cycle. Where to Install an Air Release Valve The Air Release Valve should be installed at the highest point for each drip zone. Connecting and Air Release Valve There are several ways to connect an Air Release Valve to an Irrigation supply line depending on what size of line you use. We will now provide several examples using a variety of components, all of which work on the same principle. We will look at connecting at 1/2 and 3/4" and larger distribution lines seperately.
** When using insert fittings using a gear or crimp clamp is recommended
