My yard sprinkler system has 13 stations. On at least 3 stations when they come on the water flow rate out of the sprinkler heads are good, then in a few minutes (maybe 10 or so minutes) the rate of flow will drop. I can go to the main valve (ball valve) close and open it several times and the flow will pick up again. I've never had this problem and the only thing that I can think of is my Irritrol valves (1" 2400S) may have a bad solenoid or maybe the diaphragm is bad. I have a very good filter on my system so I do not think any foreign matter has gotten pass the filter.
Any other thoughts will be much.appreciated.
WHAT TYPE OF FILTER ARE YOU USING ON YOUR SYSTEM? I AM LOOKING FOR A WHOLE SYSTEM FILTER WHEN THE WATER COMES FROM THE WELL AND BEFORE IT GOES TO THE VALVES.
