We have finally decided to bring a drilled well back in to operation. (Or so we thought) A little history on this set up. About 15-20 years ago this well was a "hub" for 3 rural houses. When we bought the place 5 years ago the system was not in operation. We decided at the time to not spend the money on updating it and just hooked or new house up to the rural water service. Fast forward 5 years and our house is done and now we are wanting to use this deep well to water our lawn. The day the well repairmen were there they took out 280 ft of sectioned line that had a 2 hp pump on the end of it. He explained to me that it would be best to put a new 1 hp pump (10 gpm) that would lift 300 feet. So we decided that's what we would do. The well is approx 460 deep and the water level is 128 ft from the surface. So after they put the new 300ft roll of black coil pipe down it I figure I have 172 feet of water from my pump to the water level. Finally it all gets hooked up and sure enough I have water. So I flushed the lines per his instruction and then hooked up one normal lawn sprinkler. Everything was going good with the sprinkler shooting about 20' side to side until I noticed the sprinkler only shooting water about 3 feet from the base (not enough pressure I presume to make it go back and forth). I went over to the spigot and turned it off and waited about 20 seconds and turned it back on. It started spraying like normal but then went back to the weak stream. When I turned it back on the pressure switch was clicking "on and off" probably 7-10 times. Is this normal? I checked the pressure in the tank with an air gauge and it had about 40psi. Also I did a bucket test and I had about 14.6 gpm. Can someone point me in the right direction for a possible problem. Conveniently my well man left today for 10 day cruise but would like to figure this out. Any help or advice is appreciated.
