Extreme southeast Nebraska | Make sure you have power to the valve. If it's a directo valve like mine, it'll only get power for one side, the other side is unenergized and the foam just flows through the valve. Check to make sure the coil is energizing (magnetized) when the switch is positioned to provide power to the valve.
Or the valve spool could be stuck. You should be able to push on the spool through the rubber cap on the valve. You should be able to push the spool in a quarter inch or less and then have it return when you stop pushing. May need to take it apart and clean it. |
