I am a new homeowner having to deal with a sprinkler system for the first time. I have done some research but can't seem to find an answer to my problem. I have a slow leak coming out from where the solenoid is screwed in to one of my valves. I thought there might be a crack in the old solenoid so I bought a replacement, but the leak is still there. At this point I am at a loss as to what could be causing it. Any help would be greatly appreciated.
