How Much Does Reverse Osmosis Installation Usually Cost in Nashville?

Reverse osmosis is a process that removes foreign contaminants, solid substances, and minerals from water by using pressure to push these things through special system membranes. As a result, this process has been known to improve the water that individuals use for drinking, cooking, and other essential uses. 

Yet, before a homeowner in Nashville decides to get this reverse osmosis filtration system installed, it is important that they first understand the costs involved with this process. Generally, installing a whole-home reverse osmosis water filtration system in Nashville can cost homeowners around $1,500, but prices can get as low as $500 or as high as $3,000, depending on the situation. Thankfully, when Nashville residents understand more about the different cost factors involved with this installation process, they can be better prepared to cover these expenses and find a contractor that will provide them with the best price. 

Cost Factor: The Size of the Reverse Osmosis Water Filtration System

Generally, the installation costs involved with a reverse osmosis water filtration system will depend on the size and the complexity of the system. For example, if homeowners only want to get a single unit installed that connects to just one faucet in the house, the price of this unit can cost them a few hundred dollars. In comparison, if the homeowners want their whole home to be able to filter all the water coming in, they can be looking at a job that will cost them thousands of dollars.

Cost Factor: Is the Reverse Osmosis Water Filtration System Certified?

An NSF certification is included on a product when it can guarantee that the specific system will remove or reduce one or more particular types of contaminants. That is why it is so vital that if you are looking for a reverse osmosis water filtration system that you find one that has the proper NSF certificates that can ensure that you are protected against harmful viruses and bacteria.

Yet, even though, in theory, you can buy a lower-priced reverse osmosis system to clean your water. Without an NSF-certified reverse osmosis system, you will never know if the system is doing the job it is supposed to be doing or how well it is actually cleaning your water. That is why for your peace of mind, it may be in your best interest to purchase the more expensive NSF-certified model. 

Cost Factor: Is the Reverse Osmosis System More Sophisticated Than Other Models?

Not all reverse osmosis water filtration systems are created the same. Some systems are more sophisticated than others as they contain various technical features that help clean the water in different ways. For instance, some reverse osmosis systems may have UV lights that kill waterborne pathogens. However, if these unique features are included, the overall price you pay for the system can be substantially more. 

What Are the Most Common Water Contaminants in Nashville?

Nashville gets its water from the Cumberland River, which is treated by both the Omohundro water filtration plant and the K.R. Harrington filtration plant. Unfortunately, even with these safeguards and cleaning processes in place, this river has been historically plagued with severe industrial pollution.

Take, for instance, the following:

Per and Polyfluoroalkyl Substances 

Per and Polyfluoroalkyl Substances or PFAS are chemicals found in various stain-resistant products and fire fighting foam. Generally, these chemicals are considered “emerging contaminants” because the EPA does not regulate them, but they are known to be carcinogenic and toxic. Unfortunately, not only have PFAS been detected at the Nashville International Airport, but Nashville does not test or try to remove these chemicals from the tap water in the city. 

Lead Elements

Generally, lead enters Nashville’s drinking water through older service pipes and lead-containing plumbing. Yet, even though both the CDC and EPA have acknowledged that there is no safe level of lead that humans should consume, the 10% of samples analyzed for lead in Nashville’s water have indicated that the lead levels are over 1.6 parts per billion in the city.

Chromium 6 Chemicals

Also known as hexavalent chromium, chromium 6 is a highly toxic chemical that the EPA does not regulate. Yet, in recent years, Nashville’s water has averaged 80.5 parts per trillion for this chemical, which means the levels are four times higher than the concentration that is determined to have a negligent impact on cancer risks.

Can Residents in Nashville Benefit From Reverse Osmosis Treatment?

Nashville is the capital of Tennessee and home to not only Vanderbilt University and legendary country music venues such as the Grand Ole Opry and the historic Ryman Auditorium. But it is also known for the District, a downtown neighborhood that is nationally recognized for its southern food, live music, and plenty of entertainment for people of all ages.

Yet, even though the city is a fantastic place to visit and start a family in, it is still essential that homeowners learn more about ways to keep their family safe and protected, especially when it comes to their water. Fortunately, this task is not very difficult to manage. When homeowners install a reverse osmosis water filtration system in their homes, they can transform their water and start providing cleaner and healthier water in no time at all. This is because this reverse osmosis system has been known to not only offer better-tasting water by reducing the contaminants that can make water smell and taste bad. But this system can also reduce the number of plastics in your home, reduce the costs associated with buying bottled water and provide your family with the water you can trust to be safe. 

How Often Should Residents In Nashville Replace Reverse Osmosis Prefilters?

It is recommended that you replace the pre-filters every six to twelve months if you have a reverse osmosis water infiltration system. This can ensure that your system runs flawlessly and that your water is protected against dangerous contaminants. 

Why Is Filter Replacement Necessary?

Filters are in place to accumulate debris to help ensure your system remains clean and in proper working order. However, as this debris builds up, it can cause clogging, ultimately making the filter useless or ineffective. Additionally, specific filters, such as carbon-based ones, can lose their adsorptive properties if they are not replaced regularly. For these reasons, it is best to have these filters replaced periodically.

Are There Other Factors That Dictate How Often the Filters Need to Be Replaced?

In some situations, it is not time that will determine how quickly you need to replace the filter but instead the filter itself. For instance, if you have an improperly installed filter or a filter that is of low quality, you may need to replace these filters much sooner than the year mark. 

That is why, regardless of how long you had the filter, if you start noticing that your water has an unpleasant taste or odor to it, or the pressure in the water supply has dropped from the tap where the filter is installed, it may be time to call in the professionals. These experienced reverse osmosis water technicians can come out and examine your filtration system and your water and figure out what the problem is. They will often:

  • Check the system’s membranes and ensure that they are correctly installed and still working properly.
  • Decide whether you need to perform a chemical analysis of the water to decide what is going on.
  • Propose that you have your filters replaced.

Do the Horizontally Mounted Membranes in the Reverse Osmosis System Need to be Replaced?

Typically, it is only necessary to change the horizontally mounted membranes every two to five years. If you are not sure if your membranes need replacement, you can either purchase a TDS meter that will perform a membrane performance test and let you know if everything is working correctly, or you can hire a water treatment dealer that can perform their own test and let you know if replacements are required.

Do You Need a Water Softener With Your Reverse Osmosis System in Nashville?

The primary job of the reverse osmosis system is to purify the water in your house by using a semi-permeable membrane to filter and reduce the contaminants in the water. Although a reverse osmosis system can soften a home’s water during this cleaning process, it is not as efficient as a water softener. A water softener’s main job is to reduce the hardness in a home’s water by using an ion exchange to replace minerals that cause your water to be hard with sodium or potassium. This exchange not only makes your water softer but leaves you with cleaner and softer hair, skin, and even clothes. 

In Nashville, where the water is considered to be hard, this distinction is significant as it can help residents figure out whether they need a water softener or just a reverse osmosis system. 

Can You Solve Your Water Problem by Getting Both?

Fortunately, if you are on the fence about this issue, a quick fix to this dilemma is to install both a reverse osmosis water filtration system and a water softener. Not only can both systems provide you the clean and soft water you want for your home, but these water softeners can even protect your reverse osmosis membranes and make them last longer. 

Typically, the water softener will work throughout your whole house, softening the water flowing in the pipelines and providing numerous benefits to your home’s appliances, pipes, and even your personal care needs. In comparison, the reverse osmosis system can be installed under a sink and provide you with purified water at a separate tap meant for drinking and cooking. 

Although both of these products can provide you with immense benefits, the best way to figure out what your Nashville residence needs is to contact a professional that can help you understand how these different systems work and whether getting both can be the solution to your water issues.
