At De Anza Water Conditioning, Inc. we understand that water is essential to our daily lives, from the water we drink and cook with to the water we use for bathing and cleaning. Ensuring that this water is clean is crucial for maintaining good health and a safe home environment. One effective method of achieving cleaner water is reverse osmosis (RO) filtration, which reduces impurities and provides high-quality water.
While many are familiar with under-the-sink RO systems, a whole-home or whole-house reverse osmosis system takes water purification to the next level, offering comprehensive filtration for every place water is used in your home. It can even be adapted to treat the water you use outside the home. In this article, we will explore what whole-home reverse osmosis is, how it compares to traditional under-the-sink systems, and the benefits it can bring to your home.
Understanding Reverse Osmosis (RO)
Reverse Osmosis is a highly effective water filtration process that removes contaminants by using a high-pressure pump to force water through a semi-permeable membrane. This membrane has tiny pores that allow only water molecules to pass through while blocking larger impurities like sodium, high levels of lead, bacteria, dissolved minerals, fluoride, and other contaminants. The process begins with pre-filtration which uses a sediment filter to remove larger particles, followed by the application of pressure to push water through the membrane. The filtered water, known as permeate, is collected on the other side, while the contaminants are flushed away as wastewater.
After passing through the reverse osmosis membrane, the filtered water often undergoes post-filtration using activated carbon filters to remove any remaining tastes or odors, ensuring it is clean and palatable. Carbon filtration alone can not filter out particles as small as the entire RO system. Using this multi-stage filtration process ensures that the water is thoroughly filtered. The result is high-quality water that is safer and healthier for drinking and other household uses and brings with it added peace of mind. Many homeowners also choose to add a remineralizing filter at the end of their system to reintroduce vital minerals to their RO water.
Water is collected in a storage tank large enough for a 1 day supply of water.
Why Reverse Osmosis?
RO technology is widely used due to its ability to effectively filter water by drastically reducing a broad spectrum of contaminants. In residential settings, an RO system provides cleaner drinking water, while in commercial and industrial environments, it ensures the filtration of water used in food and beverage production, laboratory tests, and pharmaceutical manufacturing. RO is also essential for maintaining the quality of water in aquariums, hydroponic systems, and irrigation.
Additionally, an RO system can be used in desalination to provide potable water from seawater and in whole-home filtration systems to deliver filtered water for all household uses.
According to the WQA (Water Quality Association), the main advantage of using an RO system is the fact that it is capable of removing harmful contaminants such as bacteria, viruses, soluble organic compounds such as pesticides and herbicides, and heavy metals such as arsenic, barium, cadmium, chromium, copper, lead, fluoride, and nitrate among others.
Under-the-Sink RO Filtration
Under-the-sink reverse osmosis filtration systems are compact units designed to purify drinking water directly at the point of use. These systems are typically installed under a kitchen sink and provide filtered water to a single dedicated faucet, ensuring contaminants are reduced in the water you use for drinking and cooking.
Installation involves placing the unit under the kitchen sink and connecting it to the cold water line. A dedicated faucet is then installed on the sink or countertop, delivering freshly filtered water directly from the RO system. This setup is convenient, easy to use, and provides high-quality water for daily use.
Whole Home RO System
A whole-house reverse osmosis system is a large-scale water filtration unit installed where water enters the home. This comprehensive system ensures that all the water entering your home is filtered, providing high-quality water to every faucet, shower, and appliance.
Installing a whole-house reverse osmosis system typically requires a professional setup due to its complexity and the need for precise configuration. The installation involves connecting the system to the main water supply line and integrating multiple components.
Advantages of Whole Home RO vs. Under-the-Sink RO
Whole-house reverse osmosis systems provide extensive filtration for all household water, unlike under-the-sink RO systems that only filter water at a specific faucet. This means that every drop of water used for drinking, cooking, bathing, or cleaning is purified with a whole-house system. As a result, there is a significant reduction in exposure to contaminants throughout the entire house.
Every tap delivers the same high-quality, filtered water, providing peace of mind and consistent water for all uses. This includes not just drinking water but also water used for showers, laundry, and other household tasks, contributing to overall better health and safety.
A whole home RO system offers the convenience of a single, centralized filtration system for the entire house, eliminating the need for multiple under-the-sink units in different locations. This ensures all water is consistently filtered.
A whole-house reverse osmosis system has a higher upfront cost compared to individual under-the-sink systems.
Is Whole Home Reverse Osmosis Right for You?
When considering water treatment options, conventional methods like water softeners or single-tap reverse osmosis systems often provide satisfactory results especially for water here in the Bay Area.
However, some individuals find that a whole-home RO system meets their needs more comprehensively. Some require WHRO due to specific or complex water conditions, while others prefer it for superior water quality and convenience.
Some homeowners may require whole-house reverse osmosis due to specific or complex water conditions or concerns. Whole home RO can help those with high salinity levels, extreme hardness, elevated levels of contaminants such as sulfates or other dissolved solids, or those that have water with the presence of tannins.
Households with health concerns or immune-compromised individuals also find reassurance in the whole-house reverse osmosis system’s ability to drastically reduce a wide variety of contaminants, including bacteria and viruses. Those with agricultural and livestock operations relying on water for crop spraying or animal watering can also benefit from the system’s reduction of contaminants that could impact plant or animal health.
When Isn’t Whole House Reverse Osmosis Suitable?
Whole-house reverse osmosis may not be suitable if septic pump-out costs are a concern for you. It is also not ideal if you face water scarcity issues, such as a dry dugout or low-replenishing well.
Another limitation is space, some homeowners simply do not have adequate space to accommodate a whole-house reverse osmosis system. Each of these things should be carefully considered to determine if a whole-home reverse osmosis system is the right choice for your specific needs and circumstances.
The First Step is Reaching Out to A Professional
Whether you opt for a whole-home reverse osmosis system or a traditional drinking water RO setup, it’s crucial to consult with a professional to ensure you’re making the right choice for your specific water needs. Water quality can vary significantly from one location to another, and factors such as contaminants, water hardness and total dissolved solids, household size, and usage patterns all play a role in determining the most effective solution. That’s why it’s essential to contact a professional like De Anza Water Conditioning, Inc. for a free water test and expert advice on which option is best suited for you.
