Hi -
I have a well-supplied irrigation system on the property I purchased about 5 years ago. There is a welltroll brand bladder tank attached to the wall inside the garage. I had to disconect the pump from the system a few months back and recently reconnected it. It seems to generate pressure fine and runs the spigot without a problem, but when I turn on the sprinkler system, the pressure starts out fine but after about 5 seconds there is a shudder in the pvc line going to the bladder tank and the water pressure decreases such that the sprinkler heads just dribble.

Can anyone give me the overview of how these systems are suposed to run, how i messed up, and what I need to do to fix this?
