2 Pumps, 1 well


My neighbor and I are going to share a water feed from the pond in our backyard for our separate irrigation systems. He has already been pulling water with his own pump and I plan to T from the feed prior to his pump with my own pump. We plan to water on different days so we will never have an issue with over consumption from the feed.

I have attached a picture of what I am planning on doing. As you can see the pond water comes in from the top right elbow. It goes through the T and that splits, where you will notice that both sides have a one way check valve that lead to our respective pumps.

I am wondering if this will work for us. I know from way back in high school physics that this will create a venturi effect (or a siphon like effect). When one pump starts sucking it will start moving water quickly through the T. The side of the T that has the pump which is not on will create a low pressure, but the check valve will not allow that water to escape from that closed off system, thus creating a split system.

Does this sound like it should work? Will there be any stress on the pumps that would create a problem?

Thanks in advance for all the advice!

Your system can work. I think the annoying part might be the check valves over time so I would install them so they can be easily replaced as needed.
