Backflow Prevention

Whether your dealing with back-siphonage, backpressure backflow or a cross connection, Haddad can help. We are state license and fully insured to handle all your commercial backflow problems.


Commercial Water lines provide a continous source of high pressure water and faucets create a low-pressure release. If anything causes this pressure to be interrupted, it can reverse the flow of the water and contaminate the line.

Backflow preventers are offered in an array of configurations that will take care of your heavy duty and commercial needs, helping to protect your water supply.

Backflow Prevention

Haddad provides all your commercial backflow solutions, including:

  • Installation
  • Repairs
  • Testing
  • Rebuilding
