How Do Sprinkler Valves Operate?
Automatic sprinkler valves use wires running from the control box to the valve itself, connected to a solenoid – the main component which operates the sprinkler valve and allows it to be controlled electronically.
How does a valve turn on?
To turn the valve on, a current is sent to the solenoid from the main control box. Using electromagnetic force, the solenoid raises a small plunger or piston when activated, releasing the pressurised water above the diaphragm and allowing the valve to open. When the valve is switched off and the electric signal ceases, the plunger falls again to block the flow.
Why is my sprinkler system not working?
If something is preventing water from reaching your sprinklers, the control box or wires connecting to the solenoid may be faulty, or the master water valve connecting to the water supply may be closed.
Why does my water valve keep weeping?
In case of ‘weeping’ – or failure for the valve to close completely when it’s switched off – the culprit may be a damaged diaphragm, dirt and debris build-up within the valve, or a faulty solenoid. Air trapped in the valve or insufficient water pressure from the mains can also prevent the valve from closing properly.
Can you manually operate a sprinkler system?
You can operate your sprinkler valves manually – while it is very time-consuming compared to the convenience of automation, it can be handy to know what to do in case of a fault or control box failure.
Should My Sprinkler Valves Remain Open Or Closed?
For electronic solenoid valves – the most common type used in sprinkler systems these days – the nature of the valve means they’re ‘normally closed’. This means that when water is flowing through the valve, the water pressure itself keeps the valve closed unless the valve receives a signal (or manual operation) and switches to open.
