I have installed Hunter PGV Jar-Top valves with Flow Control and noticed while flushing the lines by manually turning the solenoid on and off, the valve chatters for a second or two when closing. I do not have the controller wired yet. I did not install an air column on the main line. Is this chatter normal? Is it damaging to the valve? Should I retrofit an air column in the line?? I'm on a well with 25 - 55 PSI.
Thanks in advance for any inputs...
