What are the benefits of water softeners?


The benefits of water softening are numerous, but to name a few - The existing limescale deposits will get dissolved and disappear, giving your plumbing, heating, shower, taps and appliances an extended lease of life - saving money! And saving energy. Just a few mm of scale build up within a water cylinder will require 25% more energy to heat the hot water! The good news is that a water softener will dissolve the existing building of limescale.

Soft water will reduce your need for soaps, detergents, shampoo and water related household products by up to 75% - Massive savings here! A family of 4 will normally save enough on detergents alone to pay for a softener within a few years.

There is a benefit to the environment too as you won’t be using so many chemical detergents and cleaning agents. Along with this there are energy savings and thus a reduction in your carbon footprint.

There is also a raft of evidence supporting the huge improvement, or even cure of skin conditions such as eczema or psoriasis after using soft water.

As for Drinking water - What price do you put on health?

Water is the most important part of our diet as our bodies are made up of around 65-70% water and without it we would only live a couple of days. People spend hundreds of pounds each year on bottled water, which has the same amount of trace elements and minerals in it as tap water, believing it is “healthier” than tap water. The main reason for this is that people don't like the taste of tap water, or more specifically the chlorine or “swimming pool” taste. It is this and other compounds that makes our water safe to drink in the first place. We have to thank the water authority for this. Its a fact that we all take for granted in the modern world. However for the Water authority to treat the water to a higher degree of quality is impractical, as only about 2% of water used in the home is for drinking and cooking purposes. Imagine the cost of treating all the nations mains water supplies to an even higher standard, only to flush most of it down the drain. (See Rainwater Harvesting).

What’s the best type of water filter for drinking and cooking?

It really depends on your budget and your concerns over water quality for drinking. The options generally fall into two categories, simple, single Carbon block filters or highly advanced multi micron level, multi filtration, Reverse Osmosis systems.

Carbon block water filters

Carbon block filters are a very simple technology and inexpensive to buy and maintain. They consist of a single high density activated carbon cartridge filter that is connected to your water mains, usually under the kitchen sink area. It is then piped from the filter to a small 3rd tap located on the work top next to the sink. The filters remove the larger particles in the water and most of the chlorine taste and odours, making it more pleasant to drink, but as they only filter to around 5 microns, they still leave many elements in the water.

Reverse Osmosis drinking water systems


Reverse Osmosis is the top end technology for those serious about their health and their drinking water quality. There are up to 6 filters or stages of filtration, each one filters finer than that previous. They filter to around 0.0001 microns (about a 10,000th of a human hair thickness) in filtration and really do get rid of just about everything in the water.

What does a Reverse Osmosis drinking water system remove from the water?

Generally speaking - Tannic Acids, Toxaphene, Trichlorethlene, Trihalomethanes, Aluminium, Arsenic, Barium, Benzene, Cadmium, Calcium, , Fluoride, Iron, Lead, Magnesium, Manganese, Chloride, Chromium VI, Copper Mercury II, Nitrate, Potassium, Selenium IV, Silver, Total Dissolved Solids (TDS), Zinc; Adrazin, Aldrin, Chlorine, Chloroform, Dichlormethane, Sodium, Strontium, Sulphate, DOT, Endrin, Fluoranthene, Herbicides, Lindane, Methoxychlor, PCB, Perchlorethylene, Pesticides, Phenoles, V.O.C.'s (Volatile Organic Compounds) to name a few!

Isn’t water from RO systems acidic and therefore detrimental to health?

Due to its filtration process RO water is very slightly acidic in its ph level which can upset the bodies natural pH balance. It is for this reason that we always recommend a 6 stage reverse osmosis system with the “alkaline filter”. After the filtration process, the RO water passes through this 6th cartridge which replaces high quality trace elements and minerals and is actually slightly alkaline in pH, which is good for the body.

Isn’t removing all essential trace elements and minerals from water bad for you?

In the western world, if we eat a healthy diet, we get nearly all of our nutritional requirements from our food. However as mentioned above, we always recommend a 6 stage system with the “alkaline filter”.

A top quality Reverse Osmosis drinking water system which makes very pure water indeed, will be paid for on its savings of bottled water within a year or two - even allowing for the filter replacement cost over this period.

With a Reverse Osmosis system fitted, water really is an absolute pleasure to drink. Even the kids will drink it!
