I live in south florida and i am having issues with my sprinklers for past 4 months and my water pump not pumping water at all, so i have replaced my water pump with a new one and i checked for leaks and there are no leaks either, so i start digging the line and i found the water well and it took me literally 4 days to open the cap of that well and once opened i can see water around 15 feet deep and i connected my new pump near the pump and i did test run to see if i can pull the water but no luck, i have attached the images here and you can see in one of the images water in the well, i thought there will be another pipe inside the cast iron pipe but i dont see anything, so question is what should i do in this case to be able to water pumping from the well again?
