I'm installing a new ballast switch to control my IBS. I'm using a sprinkler valve so that I don't have to deal with vented loops and I'm not that concerned with fill time. Also using a dedicated pump. My question is: do I need to separately fuse-protect the sprinkler valve, or is the fused power wire coming into the switch enough? So the one fuse would be covering both the sprinkler valve and the fill pump?
