Certified Backflow Testing and Repair

Cary Business owners must have a backflow test conducted on their premises once a year. A licensed plumbing company and backflow certified plumbers must do this backflow test. In the testing, the valves are opened and closed to check for any anomalies, and then a form is filed to the local city to ensure that it meets the correct standard and that no code violations exist. Backflow may be a significant issue, so you should contact Alexander Services. We are backflow certified in Cary, NC to handle the backflow testing or repair. Call us at (919) 886-4822

What is Backflow?

Water distribution systems are built with the goal of directing water flow in one direction — from the distribution system to the user. However, if the hydraulic conditions inside the system diverge from “normal,” the water will flow in the other direction. As a result, in unprotected systems, it is conceivable and frequent for water to flow in the other way. This is referred to as backflow. When this occurs, the water system may become polluted with potentially dangerous substances to water consumers.

Why Does Backflow Occur?

Backflow is generated by cross-connections, which can let pollutants into the drinking water system. Back siphonage occurs when the pressure in a tank or water trough is lower than the pressure in the water system. This might allow tainted water to enter the system via inflow or pulling. Backpressure is another source of backflow. Backpressure happens when there is enough water pressure in a fire protection system or a multi-story structure to drive tainted water into the public water supply.

The technicians were very professional and communicated very well about what they were doing. They worked outside in 90+ degrees and through a rain storm. I would recommend them for any plumbing services in the future.

I was able to get an appointment to tune up my AC unit the week following the week that I called. The technician was on time - wore a mask, gloves, and shoe coverings and endeavored to stick only to the thermostats and unit in the attic and went around to the back (I live in a town home) without going through my home. I truly appreciated this approach. The unit was serviced and the cost was very reasonable. I “found” this company because my daughter uses their services too and has been very happy with them.
