I have a RainWave 4-zone watering system. It’s pretty good. The zones are independent, it attaches to a standard spigot and uses regular hoses, it’s been reliable for a couple years now.
It occurs to me that any electrically controlled watering system would have the same basic layout; the manifold for this system therefore includes, very simply, four electronically controlled on-off valves. And therefore, it should be relatively straightforward to hook that manifold to a different controller.
Anyone with thoughts to share, please chime in. Meanwhile, its time for me to do some research
