Why does my Rain Bird 100-DVF valve slam on and off?
If your Rain Bird Control Unit's valve is slamming on or off, causing water hammer, the issue might be high water pressure. Check your system's water pressure. If it exceeds 80 psi (5,5 Bars), you should install a pressure regulator on the line before the valve. This will reduce the water pressure and prevent the valve from slamming.
How to fix a Rain Bird Control Unit valve that won’t shut off completely?
If the valve of your Rain Bird Control Unit won’t shut off completely, causing sprinklers to “weep,” try these steps: * Tighten the solenoid completely (¼ turn beyond hand tight), using the solenoid handle. * Also tighten the bleed screw and bonnet screws. * Use the external bleed screw to flush the valve. If the issue persists: 1. Turn off the water. 2. Unscrew the bonnet screws and remove the bonnet. 3. Remove the diaphragm and clean it in clear water. 4. Reinstall the diaphragm and bonnet. If needed, replace the diaphragm with kit number 210746-03.
What to do if the Rain Bird 100-DVF Control Unit valve won’t open?
If the valve on your Rain Bird Control Unit won’t open, here are a few things you can check: * Ensure the water source is active. * Verify that the controller has power. * Make sure the flow control is open. If these are not the issue: 1. Turn off the water. 2. Unscrew the bonnet screws and remove the bonnet, then inspect the body for any debris. 3. If the diaphragm is missing a filter, replace it with kit number 210746-03. 4. Turn off the water again. 5. Remove the solenoid and replace it with a solenoid that is known to be working. If the valve still doesn’t open, replace the solenoid.
