Reverse osmosis systems are also more affordable than other types of water purifiers, which is why they’re becoming increasingly popular in homes and businesses.

A few of my Favorite RO Systems for Well Water

What Is a Reverse Osmosis System?

A reverse osmosis system, or RO system, is a water purifier that uses a semi-permeable membrane to filter out dissolved minerals and other pollutants. Reverse osmosis systems are an affordable way to improve the quality of your water.

Reverse osmosis systems are popular for both homes and businesses because they remove contaminants without using chemicals, saving homeowners from the taste and smell issues that come with other types of water purifiers. The membranes also last longer than other types of filters which means you’ll be able to enjoy better tasting water for longer!

How Do Reverse Osmosis Systems Work?

Reverse osmosis systems remove dissolved minerals and other pollutants by using a semi-permeable membrane. First, the water passes through a filter to remove dirt and particles. Next, the water is put under pressure as it enters a tube. Here, the water is forced through the semi-permeable membrane. Finally, as the water exits through another filter, it’s ready for drinking with all of its impurities removed.

Some reverse osmosis systems also have an activated carbon filter to remove any possible taste or odor from tap water before it goes into your home’s plumbing system.

Reverse osmosis systems are a simple way to improve your quality of life at home or in your business without breaking the bank!

What Are The Problems With Well Water?

Well water can be contaminated with a variety of things. These include:

  • Bacteria, including E. coli and salmonella;
  • Nitrates;
  • Arsenic; and, in some cases, radioactive uranium and radon.


Bacteria are the most common contaminants found in well water. In most cases it is not a problem but can be if you have a weakened immune system or if your children have been exposed to bacteria in the past. This is why it is recommended that young children should not drink well water without being boiled first. If you suspect that your well water has bacteria present, you should boil it for at least two minutes before drinking or preparing food with it. If you notice bad smells or tastes, you should have the water tested before drinking it.


Nitrates are another common problem with well water. They are naturally occurring and harmless to healthy adults but can be dangerous to small children and infants. Nitrates can also cause your blood pressure to rise in adults. If your well water has nitrates, you should boil it prior to drinking it or use a water treatment system that removes nitrates such as reverse osmosis or distillation systems.


Arsenic is another common problem with well water in some areas of the country. Arsenic is a heavy metal that over time can cause health problems such as skin discoloration, numbness in hands and feet, digestive disorders, nausea, diarrhea and vomiting. If your well water has high levels of arsenic, it should not be used for drinking or cooking but is okay for bathing.

Iron and manganese

Iron and manganese are other common problems with well water. Although the amount of iron and manganese found in the water is usually safe, if you have an iron or manganese problem in your well water, you should have it tested to determine how much these mineral levels are increasing. Sometimes high amounts of iron can cause staining on sinks, tubs and toilets while high amounts of manganese can cause discoloration of laundry and plumbing fixtures.

What Are Some Benefits of Reverse Osmosis Systems?

Reverse osmosis systems provide a number of benefits for your home and business. Some of the benefits include:

  • Removing harmful minerals and other pollutants from water, including lead and mercury
  • Increasing the pH level to make it more alkaline
  • Improving taste and odor
  • Providing fresh, pure water that is safe to drink
  • Reducing the amount of chlorine in your drinking water
  • Using less water than other types of purifiers because they don’t use filters

What Are the Different Types of Reverse Osmosis Systems?

Reverse osmosis systems are made by many different manufacturers, so there are many different types available. One of the most popular types is a whole house reverse osmosis system. A whole house system can be installed in your home to filter water for the entire house. This type of system includes an outdoor tank that collects water from rain or other sources, and then filters it before sending it into your home plumbing.

Another common type of reverse osmosis system is called an under sink system. Under sink systems are installed underneath your kitchen sink and can filter water for just one faucet at a time. These systems have their own filtration tank that attaches to the bottom of your faucet, which can be unattractive depending on where you install it in your home.

What Should You Consider When Purchasing a Reverse Osmosis System?

There are a few different factors to take into account when purchasing a reverse osmosis system for your home, which include the following:

  • The size of your water filter. This will affect how much water you can filter and store at a time.
  • What type of filters the system has. Some systems have carbon filters, while others don’t.
  • How much space the system takes up. You want to make sure that it will fit well in your space or under your sink.
  • The cost of the system. Usually, the more expensive a system is, the more features it includes and vice versa.

These are just a few things to consider before purchasing a reverse osmosis system for your home!

Is a Reverse Osmosis System Good for Well Water?

Reverse osmosis systems are excellent for well water because they help remove contaminants that traditional home water filters can’t catch. Reverse osmosis systems help reduce your exposure to heavy metals, pesticides, and other pollutants found in well water.

If you live in a house with well water, you know that it’s important to have a reverse osmosis system to provide the best quality water possible. Reverse osmosis systems remove dissolved minerals and other pollutants from water, making it more pure and healthy for your body and home. Reverse osmosis systems are also more affordable than other types of water purifiers, which is why they’re becoming increasingly popular in homes and businesses.

Does Reverse Osmosis Work with Well Water?

While a reverse osmosis filtration system is great overall for getting a clean water from your well, reverse osmosis is not ideal for treating well water with high levels of iron, manganese and other metals. If your well water has iron or manganese, a pre-filter should be added to the reverse osmosis system. A pre-filter is a sediment filter that will remove rust, sand, dirt and other small particulates from the well water before it reaches the reverse osmosis membrane.

How Much Is a Reverse Osmosis System for a Well?

Reverse osmosis systems can range in price from a few hundred dollars to $5,000. The reverse osmosis system you choose will depend on your water and how much water you need filtered. If you have a well and drink a lot of water, you should probably spend the extra money for a larger reverse osmosis system that can filter more water.

One thing to keep in mind is that not every type of well may require a reverse osmosis system. If your well is serviced by a municipal water supply, it likely won’t need one since tap water is already treated to be safe for consumption.

How Do I Choose a Good Reverse Osmosis System?

Choosing the right reverse osmosis system for your household can be tricky. It’s important to consider your water type and your needs when making a decision.

If you have hard water, you need a water filter that can remove minerals from your water. Reverse osmosis systems are made for this purpose, so it’s easy to find one that will work for you. If you have low-quality tap water, then a home filtration system might be more beneficial because they provide both clean drinking water and cleaner cooking water.

It’s also important to know what size reverse osmosis system will work best for your household. For example, if you live in an apartment with five people who drink two gallons of water per day on average, then a 3-stage RO system would be appropriate. If you live in a house with 10 people who drink four gallons of water per day on average, then a 5-stage RO system would work well.

Can You Put a Reverse Osmosis System on a Well?

If you don’t have a water well in your home, but you want to install a reverse osmosis system, it’s possible to do so. However, the process is more complicated than with other types of wells.

If you have a deep well, you will need to drill an additional hole for the mounting platform. This will create the necessary pressure for the pump that sends water through the system. If you don’t have enough space on your property to drill another hole, then it may be difficult or impossible for you to use a reverse osmosis system without major construction projects.

If your well is shallow, then there are still ways to run pipes from your water supply line into the house and install a reverse osmosis system in the basement or garage. You can also install groundwater pumps in some cases––though these tend to be less effective than using electricity.

It really comes down to how much work is required for installation and what type of water supply you currently have available. Read on for tips on what type of supplies and equipment you’ll need––and what type of project this might become!


A reverse osmosis system is a great solution for well water and will ensure that the water you and your family drink is clean and healthy. There are a few factors to consider when purchasing a reverse osmosis system, including the type of system, the cost and whether or not you want to put it on your well. You can also choose how much of your water that you want filtered. A reverse osmosis system is a great investment for your health!
