vibration at running pressure
« on: June 27, 2012, 07:32:43 AM »
The cycle valve starts to vibrate slightly at first, as pressure goes up the vibration gets worse.  Is there air in the main line

If it is a 2" or larger valve, there maybe air in the top chamber.  You can loosen the top plug to let the air out.  Air in the mainline will cause a slower pulsing, not really a vibration.
