Hello, I'm trying to turn on my irrigation system and seem to be having a problem with my backflow preventer. I turned both valves in line with the pipe, turned the small relief valves off with a screw driver and placed the cap back in on the bottom which was removed during winterizing. When I went to turn the water back on in the basement (half way since we have high water pressure), I realized the line never pressurized. I went out side and realized water kept "burping" out of the bell housing...
