A vacuum breaker valve is a backflow preventer designed to keep your plumbing system running smoothly and, quite frankly, flowing in the direction it was designed to flow. Vacuum breaker valves are also known as check valves or vacuum breakers, and they protect the potable water supply by ensuring that water flows in the correct direction and contaminated water does not flow in the wrong direction.

These valves must be inspected and/or repaired every single year by a licensed and certified backflow testing company.  One such company you can trust is City Backflow Testing who offers affordable backflow testing in many cities in the State of Texas.
