Why Skipping Backflow Testing Is So Dangerous

June 2, 2016

When selling a house in the Memphis area, you’ll be competing to be seen amidst the well-manicured lawns of swanky midtown neighborhoods. While this can certainly be intimidating for anyone selling a property, it’s important to note that landscaping is well worth the time and effort when considering your return on investment. One Virginia Tech study showed that a yard with a “sophisticated design”–in other words, great Memphis curb appeal–can increase the value of a home by up to 42%.

1. What is backflow?

What is backflow and how can it be dangerous? Simply put, backflow is the unwanted reversal of the flow of water. The flow goes back to its origins, rather than continuing to its intended destination. Backflow is dangerous because it can allow drinking water to become contaminated.

2. What is a backflow preventer?

Knowing the danger of backflow, it’s important to prevent this potential contamination. A backflow preventer is a mechanical plumbing device installed in a plumbing system that simply prevents water from flowing backwards. When installed correctly, regularly tested and maintained, a backflow preventer can reliably prevent contamination of water due to backflow.

3. What is backflow testing?

Backflow testing is simply testing a backflow preventer to verify its operation. A backflow preventer is a mechanical device, and, like all mechanical devices, will eventually fail. The test itself is very simple. Every testable backflow preventer has built-in test ports to allow for easy annual testing. All water downstream of the backflow preventer must be turned off in order to perform the test. A technician will then connect and run a test kit to the backflow preventer to verify its operation. Simple as that.

4. Why is backflow testing so important?

The presence of backflow might not be detected until it’s too late–until contaminated water has been consumed! This is why skipping backflow testing can be so dangerous. Most states and counties list backflow testing requirements in their plumbing codes, so it’s important to check on your local requirements. However, testing yearly is good practice to prevent backflow and possible contamination.

5. What is the backflow preventer failure rate?

Many elements impact the lifespan of a backflow preventer device, such as regularity of use, water pressure, water quality, and environment. When tested, about 5% of devices will display a problem, but most problems are simple. Simple problems can be due to cut seals, broken springs, or worn O-rings, whereas more serious problems, such as shattered poppets or cracked castings, are typically caused by exposure to freezing temperatures.

6. Do I have to be present for the test?

As long as the backflow preventer is outside, you do not have to be present for the test. Of course, if the preventer is inside, we’ll need someone to let us in!

In the dead of winter it may have seemed like the cold days would never end, but now the warmer temperatures will be here sooner than we think. Green shoots will begin sprouting from the ground and buds will start forming on branches. The transition from winter to spring is a welcome change of seasons. As we wait for spring’s arrival, we can help give your landscape a head start. Sometimes it is easy to forget about landscaping maintenance during the winter months. The grass and weeds are not growing like they do in the spring and summer, and your property might be covered in snow during this time. While you might be tempted to just ignore your landscaping, and wait until spring arrives to deal with it then, that would be a mistake. You do not want your landscaping to fall too far behind. So call us at Memphis Landscape and we will get your lawn and landscape ready for spring and summer! We have compiled this list of necessary tasks for a successful growing season.

Two techniques used when taking care of gardens and landscape are pruning and trimming. Trimming usually applies to maintaining small shrubs or hedges, while horticulturists use pruning for trees and shrubs. While the terms can be used interchangeably, they utilize different types of equipment and have different times for implementation. The end result of trimming and pruning are healthy and aesthetically appealing trees, shrubs and hedges. Memphis Landscape has the knowledge and know how to help you keep your yard and treelines looking great!
