Installing a Reverse Osmosis Water Softener


The King of Water Softening Systems

What does Reverse Osmosis do exactly?

All RO systems work in the same way, they all look alike, and they all have the same components.

The system has been used for years to desalinate water by way of a high pressure pump according to the expert of Water Softeners Now!

Short history of RO

RO was developed in the late 1950s with U.S Government funding to find a way of desalinating seawater. It works using pressure to force the solvent medium of water through a membrane which retains the contaminants on one side and allows the water through.

So what differences might you find?

You will find a difference in the quality of the filters and membranes inside the RO. You will need to do your homework and check online reviews to find the best system for you.

So how does it work?

The membrane is semi permeable something like cellophane allowing the water through but trapping any impurities or contaminants. These will be flushed away; the minutest particles can be trapped.

What can it remove?

RO can remove asbestos, bacteria, chlorine, sodium and viruses and much more.

If you want rid of the impure water, clean water to drink and clean water for hygiene then a good quality RO is for you.

And other advantages are;

  • 400x400xmorton-water-softener-reviews-11.jpg,q8cea62.pagespeed.ic.3QpoOdAV4eImproved odor, taste and appearance
  • No extra energy consumption
  • Extremely convenient
  • Gets rid of toxins, does not store them
  • Easy to keep clean
  • Very inexpensive way of giving you guaranteed quality water

This is a guide to fitting an RO system under the sink, a small unit with its own tap.

Tools & Materials needed

  • Measuring tape
  • Screwdriver
  • Utility knife
  • Adjustable pipe wrench 


  1. Domestic-Water-SoftenerShut of the water below the sink and turn on the taps above to drain the water.
  2. Find the recommended height to install the filter and measure up for the cabinet, screw it to the wall.
  3. Unscrew your cold water feed from the valve and install the saddle valve (included), screw the cold feed into the top of the saddle valve.
  4. Attach the supply and waste lines to the faucet (included with system). Shorten the lines if necessary to avoid any kinks forming when they are installed and fully functional.
  5. Attach the faucet to the sink and install the drain line adapter. Cut a small hole onto your waste line and attach the valve and line so that it runs from the fitting on the valve to the faucet.
  6. Set your storage tank into place and connect the supply lines.
  7. Check the manufacturer’s instructions for filling the system. Slowly turn on the faucet with the cabinet doors open to check for leaks.

That does not look so difficult now does it?

sterling-waterWhole House RO System you will probably need to think about a professional installation.

It is not something to be tackled by DIY.

For a start you will need a 300 gallon holding tank, extremely large pumps and a delicate balance of membranes

You may also need to comply with building codes which your local town hall can confirm.

Basic components of a Whole house RO System

For example all RO systems will have

  1. Water-Softener-1A cold water line valve
  2. Pre-filters
  3. RO membrane
  4. Post filters
  5. Automatic shut-off valve
  6. Check valve
  7. Flow restrictor
  8. Storage tank
  9. Faucet
  10. Drain line

Not to mention the tools and weight of some of the components.

Just because of the finer details it is a good idea to check that your RO system complies with NSF (National Safety Foundation).

Having an RO system may be initially expensive, however, by keeping appliances and pipes and hot water systems from scale build up will be a long term investment.  Not to mention the benefits of drinking healthy clean clear water.  Health is the first wealth, so if you are thinking along the lines of having a complete system without having to add salt and bypass that for drinking then RO is for you.
