The Importance of Backflow Preventers and Backflow Testing
A back flow device is also known as an RPZ valve which stands for Reduced Pressure Zone. When it comes to a commercial property, industrial building, or even a residential property, one of the most important aspects of it's plumbing involves a backflow prevention system.
A device that lets water flow through in one direction but prevents it from going backwards plays an important role in helping homes and businesses prevent flooding incidents.
In addition, it also keeps water that is unsafe from reversing its flow and entering a clean water supply, which can prove to be a serious problem. In many cases, a backflow preventer consists of a single check valve that will close when the water flow reverses.
In some cases only a small amount of water will provide enough resistance to overcome the check valve. To keep this from happening, some backflow preventers now come equipped with multiple check valves aimed to make it virtually impossible for water to flow through the valve in an improper manner.
In addition to multiple check valves, backflow preventers may also have water release valves, air vents, or other parts which allow them to be tested in order to show they are in proper working order.
To ensure drinking water is free of harmful toxins that could cause harm, it's important to have the water supply tested periodically. In addition, testing of the backflow system is required annually for commercial buildings and other larger facilities.
In most states, annual backflow testing is a requirement put in place to ensure the public has a safe drinking water supply. Therefore, when a backflow test is conducted for a business, this usually includes permits, paperwork, and submission of the test results to the appropriate authorities to show the test was conducted.
When it comes to residential testing, installation and repair of backflow assemblies, its also important to have the work done by a qualified, experienced pro.

Gate Valve Repair
For installation and replacement purposes, professionals should always be called in for gate valve problems. Reason being is that most of their intended purposes in commercial or large buildings can put the novice's safety at risk when performing maintenance.
Large diameter piping is heavy and difficult to work with in cramped quarters. Other times high pressure situations need to be verified that not only is the flow off but the system safely vented before the junction can be breached for repair.
Finally, a complete shut off from all the sources not only coming in but leaving need to be isolated as well so that back flow or other unusual situations do not come roaring back at the repairmen replacing the gate value in question.
Gate valves have a variety of valuable functions today. Actuation from one state to the other is a slow process that should utter complete results. When this does not happen, a professional needs to be consulted right away.
In addition, for the safety of the building and its inhabitants, a preventive checkup should be done on a periodic basis. Call us today and we would be happy to review your gate valve needs.
QUESTION: Why do backflow preventers have to be tested periodically?
ANSWER: Mechanical backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Also, mechanical backflow preventers and air gaps can be bypassed. Therefore, all backflow preventers must be tested periodically to ensure that they are functioning properly. A visual check of air gaps is sufficient, but mechanical backflow preventers must be tested with properly calibrated gauge equipment. Backflow Prevention provides protection of the drinking water system from contaminates and pollutants that can come from cross connections and changes in the hydraulic conditions within the system.
Q: Why am I responsible for backflow-prevention?
A: The Federal Government passed the Safe Drinking Water Act in 1974, and Georgia adopted these federal standards the same year. In 1977, Georgia passed the Rules for Safe Drinking Water which states: “A supplier of water or any person having control of facilities which may cause the contamination of public water system has the responsibility to prevent water from unapproved sources or any contaminants from entering the public water system.” The Georgia Department of Natural Resources; Environmental Protection Division, in 1983 amended this rule and mandated that all public water systems develop Cross Connection Control and/or Backflow Prevention Programs.
Q: Is there a county ordinance that covers this?
A: Yes, to augment and further reinforce the Georgia State/Gwinnett County Plumbing Code, the Gwinnett County Board of Commissioners in 1983 (the same year the state made these programs mandatory) passed Sec. 5-1012 of the Code of Ordinance, and in 1986 amended and renumbered it to SE. 5-1015, which reads in part as follows; “The county water system is further authorized to install or require to be installed suitable backflow-prevention devices at the customer’s service-connections) or other areas as needed to prevent contamination or the risk thereof for the public water system.”
