My landscape irrigation pump is not working. We had unusually cold weather in North Florida this year so I suspect that may have been the catalyst. I was out of town for several months this winter and turned off the breaker for the pump when I left. There is power to the pump, but it just hummms. No water at all. Hmmm, is it repairable or did something burst during the cold spell in my absence? My plant are getting hungry!
