As of last Wednesday my sprinklers did not work. After a lengthy investigation (pump start, breakers, wiring, timers, etc) I came to the conclussion that my 17 year old well pump had died. We replaced the pump with the same size as the previous one and water flowed. My problem is that stations 1 and 2 have a very low water pressure while 3 and 4 have the same pressure as before. We thought that the valves to these two stations maybe clogged but we arent sure. Any ideas or suggestions?
