Technical drip problem
I hope you might be able to shed some light on an unusual drip irritation problem I am having. Here is the layout for this particular zone:
The solenoid valve with vacuum breaker is at an altitude that is 50 feet above the area being watered by drippers. It releases water into a .70 irrigation line at ~34 psi. Seven hundred feet forward and 50 feet below the water arrives at the area to be dripped at ~56 psi. It then passes first through a professional size filter which has a pressure reducer (20psi) after it and then onto the drippers.
The problem is that when I turn on this system, it often does not emit water. When I open the purge valve of the filter, water and lots of intermittent air are expelled, ant then the system begins to work.
So, do I have some sort of air lock problem? The water is there, the pressure is there, but the water will not leave the system until I purge the filter.
I sure would be grateful for any help you might be willing to offer.
