What Is Backflow Testing?

Licensed technician uses an approved differential pressure gauge to verify the internal valves and seals are operating properly and protecting the water supply according to industry standards.

Simply Backflow

is a licensed, certified specialist serving Los Angeles County. We test, repair, and replace backflow assemblies — and we file the compliance report with your water authority, so you don’t have to.

Right from the start top to bottom this is a great company to work with. Sara is very upbeat, and will remember you even after a year or two. 100% we would recommend simply backflow. I am a general contractor so I know the difference between great, good & bad and they are great.

Simply Backflow has been my plumbing partner for over 10 years. Minas has unquestionable integrity and quality consciousness to be sure the project is done right. He totally stands behind his service and will happily return if any adjustment may be needed. In this day it is such a relief to be able to work with someone you can completely trust to do excellence at a fair fee. Thank you for all your help.
