I haven’t hooked it up yet, but I’m under the impression that it runs continuously. Hence sprinkler pump vs shallow well pump. The one I’m replacing is a shallow well pump that had a pressure switch and I was able to run it continuously with multiple sprinkler heads to manipulate the pressure but that wasted a lot of water. This new pump doesn’t require a pressure tank so I’m hoping it’s a better choice. I’m waiting on our typical last freeze date to install , besides I haven’t planted anything in the garden yet. About March 1st is my planned date to install.
