backflow testing

Water is a precious resource, and it's important to make sure that the water going into our homes and businesses stays clean and safe. That's why backflow testing is so important. Backflow occurs when dirty or polluted water enters the public water supply, and it can be dangerous for both humans and animals.


By regularly having your backflow device checked, you can help protect yourself, your loved ones, and your community from the dangers of contaminated water. So what is
backflow testing, and why should you have it done? Luckily, Plumbworks is here to answer these important questions.



What is backflow and what causes it?

Backflow is the abnormal flow of water or other liquids through a system or container. It can occur when there is a change in pressure in the system, causing the liquid to flow backward. Backflow can be a serious problem, as it can contaminate water supplies and cause health hazards. Several factors can cause backflow, including:


• Improper installation or maintenance of piping and other components.

• A sudden change in pressure in the system, such as a power outage or water main break.

• A blockage in the piping that prevents water from flowing properly.

• Damaged or defective components.


If backflow occurs, it is important to take immediate action to correct the problem and prevent contamination. Backflow prevention devices should be installed on all systems to help prevent backflow from occurring. These devices allow water to flow in one direction only, preventing it from flowing backward and contaminating the system.



What are the dangers of backflow?

While backflow may seem like a minor issue, it can pose a serious health hazard. When water flows backward through pipes, it can pick up harmful contaminants from the sewers and contaminate the freshwater supply. This can lead to serious illness, and in some cases, death. In addition, backflow can damage irrigation systems and other equipment. Backflow can also cause financial losses for businesses if it results in product contamination. To prevent backflow, it is important to have your plumbing system regularly inspected by a licensed professional. By taking this simple step, you can help protect yourself and your family from the dangers of contaminated water.

What To Do During a Backflow Incident

A backflow incident occurs when water in the pipes flows backward into your home or business due to a change in the water pressure. This can happen for a variety of reasons including sudden power outages or using nearby fire hydrants. Backflow can introduce contaminants into your water supply, so it is important to take immediate action if you suspect that a backflow incident has occurred.


The first step is to stop using any water from your tap until the backflow incident has been resolved. Next, contact your local water utility company and let them know about the incident. Finally, you should contact a local plumbing company to help you fix the problem. By taking quick and decisive action, you can help to prevent serious health risks posed by backflow contamination.



What is backflow testing?

Backflow testing is a process that is used to ensure that water is flowing in the correct direction. It is typically performed on systems that are connected to a public water supply, as well as on systems that use water for irrigation. Backflow testing involves attaching a device called a backflow preventer to the system. This device allows water to flow in one direction only, and it prevents contaminated water from flowing back into the system. Backflow preventers must be tested regularly to ensure that they are functioning properly. The backflow test itself is relatively simple; it involves measuring the pressure in the system and checking for leaks. If a leak is found, or if the pressure in the system is too low, the backflow preventer will need to be repaired or replaced.




Types of Backflow Prevention Devices

Backflow prevention devices are an important part of any plumbing system. They are used to prevent dirty water from flowing back into the clean water supply, and they come in a variety of different types. The most common type of backflow prevention device is a check valve. Check valves allow water to flow in only one direction, and they are often used in sewage systems. 


Another type of backflow prevention device is a double-check valve. Double-check valves have two check valves that work together to prevent backflow, and they're often used with systems that may deal with substances that have low toxicity. Lastly, there are air gap devices. Air gap devices create a physical barrier between the clean water supply and the dirty water, and they're effective against backpressure and back-siphonage issues. Backflow prevention devices are an important part of any plumbing system, and they come in a variety of different types. Choose the right device for your needs to ensure that your water supply stays clean and safe.


How often should you perform backflow testing?

Backflow testing is an important part of maintaining a safe and healthy water supply. Backflow preventers are installed in plumbing systems to keep contaminated water from flowing back into the clean water supply. However, backflow preventers can become damaged or worn over time, allowing contaminated water to flow back into the system. That's why it's important to have your backflow preventer tested on a regular basis. The frequency of testing will depend on the type of backflow preventer you have, as well as the risk of contamination in your area. However, most experts recommend having your backflow preventer tested at least once a year. By having your backflow preventer regularly tested, you can help to ensure that your water supply remains safe and clean.




Who should perform backflow testing?

Although backflow testing is not required by law in all states, it is always recommended to have your backflow devices tested annually by a certified professional. This is especially important for businesses that are required by law to have their backflow devices tested, such as restaurants and other food service establishments.


A certified professional will have the knowledge and experience necessary to properly test your backflow devices and ensure that they are functioning properly. In addition, a certified professional will be able to identify any potential problems with your backflow devices and make recommendations for repairs or replacements as needed. Ultimately, having your backflow devices tested by a certified professional is the best way to ensure that they are functioning properly and protecting your business from harmful contaminants.

If your home is 30, 40, or even 50 years old, there’s a good chance your gas piping system hasn’t been updated since it was installed. Unfortunately, aging gas pipes can put your home and family at serious risk. Gas lines naturally degrade over time, and older materials are much more likely to develop leaks, corrosion, or even sudden failures. In metro Atlanta, soil conditions and humid weather can speed up deterioration, making it even more important to have your system inspected if your home is decades old. At Plumb Works, we’ve seen firsthand the dangers of outdated gas lines in Atlanta-area homes. Here’s why you shouldn’t wait to have yours evaluated. Why Old Gas Pipes Are a Serious Hazard Gas lines may last for decades, but they don’t last forever. Many Atlanta homes built between 1975-1995 used black iron or galvanized steel gas piping. These older materials are prone to: Corrosion and rust: Atlanta’s humid summers and occasional flooding can accelerate corrosion, especially in crawl spaces or underground lines. Loose connections: Changes in temperature between the hot southern summers and colder winters can weaken threaded connections, leading to leaks. Outdated materials: Galvanized steel pipes used in the past can flake apart internally, causing dangerous blockages. Lack of protective coating: Modern gas lines are coated with fusion-bonded epoxie (FBEs) to resist corrosion, but older pipes generally don’t have that protection. Even small leaks are dangerous because there is no safe level of exposure to natural gas. Natural gas is highly flammable, and any exposure can also lead to serious health issues, including headaches, dizziness, nausea, or even suffocation at high levels. Warning Signs Your Gas Piping Needs Repair or Replacement Because most gas piping runs behind walls or underground, spotting problems isn’t always easy. Here are a few red flags to watch for: A rotten egg smell (the odorant added to natural gas) Hissing or whistling sounds near gas appliances or lines Dead patches of grass above buried gas lines Visible rust or corrosion on any exposed pipes A sudden or unexplained increase in your gas bill If you notice any of these, call a licensed plumber right away. Gas leaks are an emergency and should NEVER be handled as a DIY repair. What Atlanta Homeowners Should Do If Your Gas Piping Is 30-50 Years Old If your home’s gas lines are decades old, schedule a professional inspection even if you haven’t noticed issues. Licensed plumbers in Atlanta, like Plumb Works, can evaluate your system, locate leaks, and determine if repairs or a full replacement are necessary. Modern gas piping materials like CSST (corrugated stainless steel tubing) or polyethylene piping last longer, resist corrosion, and are more flexible for installations around Georgia’s clay-heavy soil. Upgrading your system will not only make your home safer but also more efficient. Don’t Wait Until It’s Too Late Delaying repairs or replacement of old gas pipes can have devastating consequences, including fires, explosions, or carbon monoxide exposure. Addressing the problem now can keep your family safe while protecting your property (and your wallet) from major damage. It’s also crucial to bring your home up to Georgia’s current safety codes. Call Atlanta’s Trusted Gas Line Repair Experts If your Atlanta home was built from 1975-1995 and you’ve never had the gas piping inspected, now is the time. Plumb Works, Inc. specializes in Atlanta gas line repair and gas line replacement . We understand the unique challenges of Georgia’s climate and soil conditions and follow all City of Atlanta and Georgia state codes for gas line safety. Don’t wait until a small leak turns into a dangerous emergency. Call us today or schedule an appointment online using our self-scheduler. Our licensed plumbers will perform a thorough inspection and give you peace of mind knowing your home’s gas piping is safe.

As fall brings cooler temperatures and vibrant foliage, it’s easy to forget that falling leaves can create significant problems for your storm drains. Both residential and commercial properties are at risk, especially when regular maintenance is neglected. In this blog, we’ll discuss the importance of cleaning storm drains, how leaf buildup leads to overflow, and why keeping up with maintenance can prevent expensive repairs. The Problem with Leaf Buildup in Storm Drains Fallen leaves may look harmless, but when they accumulate in storm drains , they create blockages that prevent water from flowing freely. This can cause: Overflowing drains in parking lots Water damage to building foundations and basements Unpleasant smells, especially for commercial properties that haven’t maintained their storm drains in 5+ years Leaf buildup is often forgotten until it’s too late and the water starts overflowing. Regular cleaning is the key to preventing these issues. Why Regular Maintenance is Essential Storm drain maintenance should be conducted at least once a year, or every other year in lower-risk areas. This can include: Camera inspections to check for blockages or damage. Jetting lines to clear out leaves and other debris. Maintenance is especially critical if your home or commercial property sits below street level. Properties at a lower elevation are more susceptible to flooding, and clogged storm drains can make this worse. If your house or business is above street level we recommend you perform storm drain maintenance once every 2 years unless you notice frequent leaf buildup in the storm drain grates on your property. The Dangers of Waiting Too Long All it takes is one large storm for clogged drains to cause a sewer overflow. While overflow often occurs in parking lots, the worst-case scenario involves water backing up into your building’s foundation or basement. This can lead to structural damage, mold, and costly repairs. For commercial properties, water damage can also disrupt business operations and create liability concerns. Property owners who neglect maintenance for five or more years might even notice persistent foul odors, which could indicate significant buildup and the presence of trapped debris or stagnant water. How to Prevent Overflow After a Storm The best way to prevent storm drain overflow is to stay on top of regular maintenance. However, if a storm hits and you suspect your drains may be blocked, it’s important to act quickly: Check for standing water in low-lying areas or parking lots. If you notice an overflow, call a professional to inspect and clear your storm drains immediately. After heavy storms, consider scheduling a post-storm inspection to ensure everything is functioning properly. Protect Your Home and Business With Plumb Works Storm drain cleaning is an easy task to forget, but it’s crucial for avoiding water damage and keeping your property safe. By maintaining your drains yearly or every other year, you can rest easy knowing your property is protected from the dangers of leaf buildup and storm drain overflow. Whether you own a home or a commercial building, regular inspections and maintenance will save you from costly repairs in the future. Don't wait until after the next big storm— schedule your storm drain cleaning with Plumb Works today!
