Hi, After posting on many forums I found that there is a leak/dripping in my sprinkler system. For the time being I have shut the water flow to the Sprinkler System. Here are some images: Some people suggested that it is Loose Packing Stem Ball Valve. I have no idea what does that mean!! Does anyone has videos or articles or links on how to solve this dripping/leaking problem. If I call the repairman how much am I looking at $$? This happened because of cold weather.
