Hello, I have one Rainbird zone that trickles water after the system is off. I've been told that the valve my be dirty. After locating the valve, I see that there a 5-6 screws that hold everything together. I didn't want to create more problems, so I didn't remove the screws until I asked for some advice. In order to clean the valve, do I need to remove those 5-6 screws? Also, there is a little "peg" sticking up from the valve; is that how I bleed it? If so, how do you go about doing that? Again...
