I will be moving into my first home soon, and it has a lawn sprinkler system installed. I had the home inspected, and in the report it was noted that the sprinkler system poured water from the vaccum breaker. I have a picture of this and wondered what the problem could be. I have been doing some research online and cant figure out if its a AVP or PVB or what. If I attach a pic could someone determine the type and possibily the solution to what would cause water to come out of there and not any of the sprinkler heads? I'm pretty handy and would like to repair this on my own. Any suggestions?
