I just had a system installed in conjunction with some new landscaping i was doing. Also needed separate RPZ install for city of atlanta irrigation meter. On very short notice David fit me in perfectly with our landscaping timeframe and also did a superb job with the RPZ install. My neighbor just had to do RPZ for city requirement too, paid the same amount as I paid David, and it looks like a butcher came to their yard. You can hardly tell David was there. High quality install in my opinion.
