I have a 40 ft deep well with a 6" Pvc casing. The wells water level is 20 ft below ground level, and i would like to use it for irigation. My largest zone currently uses 11.5 gallons per minute using municipal water at 40 PSI. I tested my well with a 1/6 Hp submersible utility pump
submerged 1.5 ft for 2.5 hours without any noticeable drop in water level. I would like to use a 4" submersible pump with a bladder tank so i can also hand water. What size pump and bladder do you recomend. I have a Simer 1/2 hp 2 wire 12 GPM pump available for free, but would like some input before I do anything
Thank you
Andre
