Recommended Customer Reviews

Chris is honest, reliable and efficient. What you see is what you get. He is definitely an expert at his trade. We have used him for several years to test and maintain our backflow. When the cost to maintain an old poor quality backflow began to outweigh a new unit, Chris was very honest to recommend replacement. We are approaching tackling an audit on our current irrigation and I will certainly put Chris at the top of our list to manage this.

I had a sprinkler/backflow issue and every contractor I called seemed to have a different solution. I finally found Chris' website, which lists his multiple credentials (beyond simply being licensed by the state), so I emailed him. He replied in detail, explaining why most of the advice I'd received was incorrect. It was clear he knew his stuff - and his recommendations also matched what the local water agency advised. I was grateful for his expertise, professionalism and experience.

Chris made multiple visits and went above and beyond to get the job done. He even took a crack at fixing a broken part, and when that didn't work he waived the fee. Just awesome!

We were watering by hand but decided to plant new bougainvilleas and other succulents and needed an updated functioning sprinkler system but the gardener was unable to turn on the backflow. It was outdated, old & broken. Luckily we found Chris from a referral and he installed a new backflow, worked diligently, like a detective, and got the the sprinkler system working properly. Chris works in North County San Diego, CA
and is a certified specialist in many areas of testing, service & repair and a member of numerous professional associations that keeps him updated. He is a proficient qualified expert that can do the job correctly and he will explain all you need to know about your system. You can't go wrong with his many years of experience and knowledge.

This guy is the real deal. He lives backflow and if you want someone that is qualified call Chris.
