In short, this battery operated controller and 9v solenoid kit is an absolute solution when you've got no power to a sprinkler valve, either because the line has shorted to the control box or there is no power to the valve. This nifty battery operated controller and solenoid combo works off one or two 9v batteries and the provided solenoid swaps out with the solenoid already on your Rain Bird valve.
We lost electrical to one of our lawn stations and, after chasing and testing all the easy stuff, determined that the electrical line was broken somewhere buried under 110 feet of sidewalk, driveway, and patio. We are DIYers and learned about this option. Supply stop had the best price around and the unit arrived quickly. We read the easy instructions and the unit was on within 10 minutes. It was easy to program the 1-station controller and it absolutely works on schedule and flawlessly.
