The pump was short cycling the last time the sprinkler was on last year. This year won't even pick two heads up. They heads should pop at 25#. So if I got pressure volume most be the problem?. I did not check it for proper cycling, I added air because of that. I know that more air does not produce more volume, and it had only 28# in the bladder. Pressure setting is on @ 40# off at 60#. What I am going to do first, is blow the well out and hope to clear it that way. Second I will pick the pump off the bottom by 5 feet. Then if all this has failed to give me the volume I need.......NEW PUMP! OR new well?
