Atlas Backflow Services

​Call for a Quote


When you need a certified backflow testing company in Los Angeles or throughout Orange County, give us a call. We can give you a quote for testing, repair or replacement by one of our certified backflow technicians.  When contacting us, kindly note the following. How many backflow test and maintenance reports were sent to you from the Water Company? The cost to test 1 backflow assembly will obviously differ from testing 10. If you know where your backflow preventers are located on your property, do a quick visual and look for any signs of leaking or damage. In most cases, a leaking assembly is a failing assembly. Atlas is the premier Backflow Tester in Los Angeles.

*Discounts available on multiple tests*

Beware of Theft

Backflow theft in Southern California is a big problem. Copper and brass prices are at their highest, and water valves, such as Backflow Preventers, present themselves as easy targets. Make sure the assembly hasn’t been stolen and the backflow preventer cage is intact.

Backflow Testing Los Angeles

Your average 2” Water Backflow weighs in between 35 and 50 lbs, and can be scrapped at your local recycling yard for around $2.00/Lb. These assemblies are not difficult to steal. Anyone with a sawzall and about 15 seconds of time, can snatch your backflow and leave you with a hefty bill in both assembly replacement and water loss. 

Don’t be the one to get caught off guard… protect your brASS!
