Each sprinkler head on our site has a published performance chart from the manufacturer stating how much flow and pressure it takes to operate each size sprinkler and lists the performance data of the sprinkler at a chosen flow rate and pressure setting. Most sprinklers will operate in a wide range of flows by simply adjusting the nozzle size to match the flow capability that your well or pump provides.
