irrigation systems with centrifical pumps
« on: November 19, 2012, 10:47:10 AM »
How can you set up your valve system with centrifugal pumps to turn on automatically with centrifugal pumps that do not have flooded suctions and must be primed before turning on?

The CSV doesn't do anything and acts like a piece of pipe until the water gets up to the set pressure of the CSV.  So if you are turning on a self priming centrifugal with a timer, the pump will prime, the pressure will increase, and then the CSV will start working to control the pressure to the sprinklers.
