I currently have a shallow well (22'). My well pump is feed by two 1.25" well points connected at a "T". I want to install an irrigation system with an irrigation pump. My current pump just doesn't have the power needed for irrigation, but it is good for general watering. So, I want to tap into my current well at some point. There would be two pumps on the well points, but they would not be run simultaneously. I'm thinking I tap in just above the "T" from the two well points, but where would I locate the check valves to make sure one pump doesn't remove the priming water from the second pump. Or, am I just going the the completely wrong direction?
