A backflow preventer keeps water flowing one way, into the property and never back into the public supply. It sits where a reversal could pull irrigation water, standing water or something from a business back toward the clean water everyone shares. Most of the time nobody thinks about it, until a test notice shows up.
In Santee, many businesses along Mission Gorge Road and around Santee Town Center, from restaurants to medical offices and auto repair shops, have backflow assemblies that need regular testing. So do some homes with irrigation. When an assembly fails its test, leaks, or is too old to rebuild, it needs repair or replacement by someone licensed, and a retest by a certified tester.
This is what the service covers. Testing by a certified backflow tester, repairs and replacements done by a licensed contractor, and the report sent where it needs to go. You hear what the notice means and what the device needs in plain English before any work is done.
