Just so, what is an irrigation control valve?
Valves control the flow of water to the irrigation system. Each valve is responsible for one area, or zone, of the lawn irrigation system. When the solenoid receives the signal from the controller, it tells the diaphragm to open, allowing water to flow through the pipes, or close, to shut off the flow of water.
One may also ask, how do I know if my sprinkler solenoid is bad? If your solenoid is bad, the water pressure in the sprinkler chamber will not be changed and the valve will fail to open.
- Turn off the water supply.
- Open the solenoid housing and inspect the plunger.
- Reinsert the solenoid plunger into the housing.
Subsequently, question is, what causes a sprinkler valve to stay open?
Air Trapped in the Valve: A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.
How do you troubleshoot an irrigation valve?
Replace the valve body if the valve seat is damaged. Check the diaphragm and the valve seat for cracks and wear. Replace them if they show signs of wear or deterioration. Reassemble the valve, turn on the water, and manually operate the irrigation controller to make sure everything is working properly.
