Jason called because he had bought the house recently and wanted to make sure the system was buttoned up as well as learn as much as he could about it. We located backflow and checked the system. We found the system to be a little aged but functioned normally. There were a few heads that were stopped up completely that we changed out as well as a few heads we changed out to 12 inch heads to improve coverage due to the plants outgrowing the heads. Once work was complete we checked entire system over again to check for any leaks.
