Let's look at the Reverse Osmosis Process and how drinking high-quality, pure water, every day can help our health and save us money.
The Reverse Osmosis Process:
The Reverse Osmosis membrane consists of many layers of spiral wound filaments that restrict the passage of contaminants and force them to the drain. The product water is drawn from the inside of the membrane and sent to the RO water storage tank before it goes through final carbon filtration as it goes to the RO faucet or refrigerator. A typical residential Reverse Osmosis system makes anywhere from 10-75 gallons per day of high-quality drinking water depending on the TDS (Total dissolved solids) of the incoming water supply, feed pressure, and the temperature of the feed water. Generally, the higher the TDS (Total Dissolved Solids), the less product water is produced and lower quality water will be created. For high TDS water a “Booster Pump” is incorporated to boost the incoming water pressure through the membrane to improve the quality and quantity of water the product water produced.

When it's feasible, it is recommended to have the reverse osmosis system installed in the basement for easy maintenance, ease of filter changes and not tie up valuable space under the kitchen sink. Larger storage tanks can be used when installed in the basement and product tanks can even be hung in the floor joists to help with water pressure to the RO faucet and refrigerator. Delivery pumps can also installed to boost the pressure from the storage tank to run water across the basement to operate refrigerators efficiently and supply higher pressure to multiple locations and RO faucets. RO filters are changed every 6-12 months and the RO membrane is changed every 3-7 years depending on water usage and incoming water quality to the RO system. Filter changes can cost anywhere from $60 to over $200 depending on the RO system and the type of filters to change. RO membranes generally cost $65 to $120. Anyone can change these filters but certain procedures should be followed when changing RO filters to protect against bacterial cross contamination from our hands that can potentially contaminate the RO system and drinking water. Periodic sanitizing of the complete RO system is recommended to prevent possible contamination.
There are three styles of residential reverse osmosis systems:
2. 3-4 stage RO system with a one-piece manifold and replaceable filters
3. 3-6 stage RO system with a one-piece manifold and quick change filter cartridges
Reverse Osmosis storage tanks come in many sizes to accommodate necessary water storage:
Rather than getting into the histrionics about dangerous things that can potentially be in our water and how they can be hazardous to our health, let’s address one fact. We all need to drink more water! Our Doctors tell us that, our bodies tell us that every time we get thirsty, we all need to stop drinking so many sugary drinks, energy drinks, coffee, drinks with artificial sweeteners, etc... Dehydration is the number one contributor to health-related issues. Our bodies are over 80% water so keeping hydrated is of the utmost importance and drinking water is the only way to stay hydrated.
Purchasing water for the home is time-consuming, expensive, and a pain to constantly buy bottles of water or schedule water deliveries. Not to mention finding the space to store it all. We all need to drink more water, and many of us are as evidenced by the bottled water flying off store shelves and being delivered to households every week. The bottled water industry has been growing by nearly 15% annually. A Reverse Osmosis drinking water system is the answer to this problem and the most practical way of having all the quality drinking water we need (AT PENNIES PER GALLON) and giving your family high-quality drinking water 24/7, 365 days a year. So do yourself a favor! Get a Reverse Osmosis system for your home and family and DRINK UP there is plenty of water for everyone!
