Founded by Gene Greene more than 30 years ago, Greene Backflow is still a family-operated company. Started by Gene Greene in 1981, Greene Backflow is now overseen by his widow Lynn Greene, his eldest daughter and son-in-law Candace and Joey Guzman, and his youngest daughter Samantha Greene.
All three, Candace, Joey, and Samantha, hold certifications as backflow testers from AWWA, LA County, OC, and Ventura County.
Gene pursued Landscape Architecture at Cal Poly and completed a Backflow Prevention course at LA Trade Tech during the ""Good ol' days,"" as he liked to call it, ""just for fun."" He earned his plumbing contractor's license in 2013, again ""for fun.""
Candace graduated from Cal State Northridge with a degree in English and Communications and completed her Backflow Prevention course through the USC Foundation for Cross Connection Control in January 2012 because, as Gene advised her, ""it'd be a good idea if you do."" In 2018, Candace passed the CSLB exam for plumbing and now holds C-36 license #986747.

Recommended Customer Reviews

Green Backflow has been our go-to for Backflow testing @ our home each year. We've booked with them for the last few years now always without any hassles. They're very friendly, fast and easy to book.

We were having an emergency with our last backflow testing company, and called Greene in a panic. Candace called me back immediately, and was able to fix the problem in a matter of hours. She scheduled us in, they conducted the test, and turned the information over to the city that same day. Her customer service skills were second to none. We will only be using Greene Backflow Testing and Repair going forward, and would HIGHLY recommend their services to anyone!

Good people. Fantastic customer service. Realized our Backflow testing was due to the City in 7 days. Found this company through a google search and could not be happier with their service. My first call to them was 4 pm on a Friday. Candace had someone to the property by 8 am on Monday morning and the paperwork was submitted later that day to the City. Fantastic! I have since used them on another one of our commercial properties in Moorpark. I highly recommend!

Super nice people that run this company. They only come to check the backflow device where I work once a year, but they are so pleasant to chat with that I felt compelled to write this review. It is because I support family run small businesses which are passed from one generation to the next, like Greene Backflow. Yes they are Santa Clarita Local Yokels, and they grew up here when there was no traffic jams on Soledad.
If you own a business, you most likely have a thing called a ""Backflow device"" on your property hidden away from sight because it's an ugly metal contraption that sticks out of the ground. It needs to be tested once a year, btw. You should call Greene Backflow to do it because they're fair-n-square when it comes to pricing, honest, and absolutely lovely people to talk to.
