I am installing an irrigation system supplied by a submersible pump. the well was just recently drilled and is producing 45gpm at 74 feet total depth is 125 feet. I am installing a 3hp 27 gpm pump. I know what the pump and delivery requirements are but I'm not sure how to plumb it without a pressure tank. The system will be powered by a generator tied in to a breaker box through the controller to the pump. Similar systems we have installed that free flowed to either irrigation or to ponds did not have pressure switches or low pressure cut out switches installed. They were manually operated and monitored during operation. There was no concern of over pumping. The wells were running 5hp pumps pumping 85 to 100 gpm at 50 feet. They regularly run 72 hours straight. Since this well is new I'm concerned of the possibility of over pumping. Should I install a low pressure cut out switch and how do I plumb it without the tank? Can I cap off the tee that feeds the tank and still have a switch, gauge and pressure relief valve on the tee? any input recommendations or suggestions would definitely be appreciated.
