Purchasing A Whole House Well Water Reverse Osmosis System - A Quick Guide
A Whole House Reverse Osmosis (RO) system is a highly effective and popular technology used by many homeowners to purify well water. There are a wide variety of RO systems on the market so it can be overwhelming when trying to find one that meets your household's exact requirements. If you are currently looking for a whole house RO system and want to know how you can benefit from using a reverse osmosis, what to look for in a RO system and what questions you should be asking, then this quick reference guide is for you.
If, after reading our information, you still have some unanswered questions our team at RainDance Water Systems are happy to help. We can be contacted at Support@RainDanceWaterSystems.com or call 1-877-788-8387.
How much does a whole house reverse osmosis system cost?
A whole house reverse osmosis system will cost anywhere from $5,000 to $15,000+ depending on your water chemistry, how much water you need to make, storage tank size, pretreatment needed and overall design of the RO unit.
What is Reverse Osmosis?
To understand what Reverse Osmosis is you first need to
understand osmosis. In simple terms, osmosis is the movement
of a solvent, for example, water through a semi-permeable
membrane from a region of lower concentration to a region of
higher concentration to achieve balance on both sides of the
membrane. This movement occurs naturally without any energy
being applied. To stop this natural process from occurring
you need to apply pressure to the higher concentration side
of the membrane. The osmotic pressure is the pressure
difference needed to stop this natural flow of the solvent
across the semi-permeable membrane.
For reverse
osmosis to occur, you apply a pressure that is higher than
the osmotic pressure. This forces the solvent through the
semi-permeable membrane in the opposite direction to that
which occurs naturally with osmosis, leaving any impurities
behind. The water passing through the membrane is referred
to as the “permeate” (or product water) the remainder is
referred to as “concentrate” (or reject/drain water). As the
RO membrane only allows a minute amount of salts in the feed
water to pass through, the conductivity of the permeate is
very low, whereas the concentrate is very high in dissolved
salts.
Do I need a whole house RO system?
Reverse osmosis technology produces purified water, so it
may be suitable for any household that needs high quality
water for any reason.
There are many reasons why some
homeowners choose an RO system over other technologies. For
example, water purified using an RO system may be used to
remove high total dissolved solids (TDS) from well water.
For other applications the RO system may be used to reduce
arsenic, chromium, sulfates, nitrates, chloride, sodium and
other contaminants.
Basically, if you need your
water to be of a higher quality than your private well
water, then an RO system might work for you. As there are
many different RO water filters to choose from, it is worth
having your water analyzed. Before you purchase any whole
house reverse osmosis water filter for your well we
recommend that you obtain a water quality test report for
your well water supply, which will help identify any issues
that are essential to deal with and those you may wish to
improve. If you have a water report please email us at Support@RainDanceWaterSystems.com

How much water does a whole house reverse osmosis system waste?
All whole house RO systems waste water and require a drain source. However, the RainDance whole house reverse osmosis systems incorporate a recirculation valve which conserves water and allows for less water going down the drain. *Typical recovery for these systems are 50% (1 gallon of pure water to 1 gallon of waste water) up to 70% (2 gallons of pure water to 1 gallon of waste water). Most of our competitors advertise higher waste water and a lower recover of only 33% *The amount of waste water can be determined by your water chemistry. If you have a water report please email us at Support@RainDanceWaterSystems.com Attn: Whole House RO For Well Water - All of our whole house reverse osmosis systems are manufactured to be water efficient using the latest up to date membrane solutions software.
In some cases the waste water from a whole house reverse osmosis system can be re-used for other purposes such landscaping, irrigation, wash down water and more. With some planning you can waste very little water - ask us how
What size whole house reverse osmosis system do I
need?
The usual sizing formula for a Whole
House RO System is 100gpd per person plus miscellaneous
uses. You'll then double this number to find the
appropriately-sized RO system. For example, if the usage
needs 400gpd then an 800gpd RO system would be appropriate.
This allows the accommodation of continuous use plus some
extra capacity in case the usage increases in the future.
Keep in mind that an RO's rated capacity (gallons per
day, or GPD) means what the system can produce in a full 24
hour period. For example, an 800gpd RO system can produce
800 gallons in 24 hours, or approximately 0.5 gallons per
minute (GPM). This is why a separate RO product water
storage tank and repressurization pump are needed to deliver
high flow, pressurized purified water to multiple taps.
How Does A RainDance Whole House Reverse Osmosis System Work:
Pressurized water from your well water source first enters the built-in prefilter cartridge system for extra membrane protection from sediment, debris, rust, and more. Then this “pre-filtered” water enters the RO purification membrane. Through the process of reverse osmosis, water is pushed through a semi-permeable membrane at high pressures to separate contaminants from the water. Contaminants are flushed to the drain, but before this water is wasted, the drain runs back through the RO membrane to "reclaim" water for less waste. This reclaimed water turns into purified water, which then enters the remineralizer to protect the home's plumbing and appliances from corrosive RO water by adding a small amount of minerals back to the water. Pure, remineralized water then begins to fill the near-by storage tank, and the RO water will continue to fill the storage tank until the tank float switch closes and shuts off the entire system. When there is a demand for water the re-pressure delivery pump is activated and draws RO water from the storage tank and sends it to your taps. If enough product water is used to the point where the float switch is reopened, the RO system is automatically reactivated and begins to replace the purified water that has been depleted.

Where are your whole house reverse osmosis systems made?
RainDance Water Systems is a US based company. All whole house RO systems are made and assembled in the USA (California)
NEW! Easy Automatic RO Control Panel
now included with the RainDance TSM Whole House RO Package. Our
integrated electronic controller offers automated control of
several system functions and helps prolong the life of the
RO motor and membrane, providing long-term and reliable
operation. Built with superior engineering, this control
panel eliminates confusing switches and lack of feedback
provided by other generic RO systems.
The Automatic RO Control Panel
allows the home owner to easily monitor the performance of
their system by using easy-to-read light up indicators for
common RO functions. Certain features such as the System
Flushing and Low Pressure provide added
protection by automatically cleaning the RO membrane and
shutting the RO system off in events of low water pressure.
Low water pressure can cause an RO system to cycle on and
off which can burn out the motor and increase noise level.
Other features like the RO Pump and Tank Full
keep you informed when the system is running and you have a
full tank of purified water. With automated control it has
never been easier to operate a whole house RO system!
