Overall system check and repairs. Home was built 2 years ago so system is brand new. Contractor used was subpar and there’s signs of poor workmanship like excess glue in all the filters of the nozzles. Advised homeowner to keep an eye out on things breaking. Replaced 2 heads in zone 2. Replaced 2 nozzles in zone 4 Replaced 2 regular nozzles w/ MPs in the rotor zone 5.
