Rainbird ESP Modular system troubleshooting
| | |
Posted by alect z10 CA (My Page) on Sat, Oct 10, 09 at 21:37
| we have a Rainbird ESP modular controller for several zones around the front and back yards. It has been working fine until one day our water tanks emptied for no good reason. I have investigated and it seems that the system emptied the tanks as Zone 1 is currently on - so I tried to switch it off - reset all programs even switched to manual - but still Zone 1 is ON. I even switched the controller to OFF and Zone 1 is still ON.
Is this a valve problem? How do I troubleshoot and fix it? |

If the clock is not responding to commands, remove the back up battery and disconnect clock from all electricity for a short time such as 60 minutes so the clock will loose all programming and you can re-program clock. If your clock is hard-wired and not a plug in type, just flip off that breaker for a bit and reprogram. If the clock is operating normaly and the problem is the valve itself, then it is either debris in the valve diaphram or solenoid or a bad solenoid. Turn off water at the main and open up valve and clean out the diaphram and the solenoid too. Or buy a new valve with solenoid and replace the whole top of the valve |

| I think the clock is fine (or at least not the problem) since even when set to off Zone 1 is ON. So I raised the cover of the valves and there are 4 down there and I don't see markings to tell which is which. How do I know? How do I remove the top (vale and solenoid)? Just pull them off? Each also seems to have an OFF/ON switch next to the top of the valve - each seems to be set to OFF - what are these manual overrides? Can I manually override the solenoid/valve setting? |

| Sounds like the #1 valve is stuck open. Probably something stuck between the diaphragm and seat. You should be able to locate the right valve by looking at the color wire attached to the #1 terminal on the controller and then finding the valve in the box with that same color. Then you will have to shut off the water at the supply. If your a handy guy, you can then take the top portion of the valve off. If it is a jartop type of valve, just loosen the cap and remove. Just be careful as there is a spring in there along with the diaphragm. You can then check for any debris or a damaged diaphragm seat Be care ful as you do not want to introduce any dirt into the valve. If it is not a jartop, but is held by screws, remove screws and pull top off. I would start with this and see what you find. Be sure to put it back together the same as it was. |
